Makes cell counting fast and easy! Disposable slides are so much easier to use than a conventional hemacytometer.

The Cellometer is very useful - it saves us an immense amount of time. We use it every time we plate. Thanks for a great product!

The Nexcelom Cellometer increased the amount of cell samples I could count in a day, increasing the amount of data points I could derive. Additionally the sheet of viable cells/non-viable cells, cell diameter etc. was extremely helpful. I used the Cellometer for counting SHSY-5Y cells. - Kaeli Freeborough, Lake Erie College of Osteopathic Medicine

We use the Cellometer Mini. It's my favorite tool! Allows for assays that require many, many, many cell counts to be doable.

I love the simplicity and user-friendliness of the instrument. I learned how to count cells on a hemocytometer, which was tedious and required too much precious time. Not to mention, the hemocytometer and coverslips were extremely easy to break which, added up to a lot of replacement costs. With the Cellometer disposable slides I don't have to worry about any of that, and the computer does the counting and math for me. In addition, I love being able to adjust the settings so that it can count smaller cells such as immune cells. Sometimes, we have samples that have immune and/or cancer cells mixed in with red blood cells, and being able to gate out the rbc's through size is a convenience that I am extremely grateful for.

With Cellometer it is really easy and quick to visualize our cells and perform counting. Cellometer also enabled us to read RFP and GFP Taransfected cells very quickly - Neha Bhise, University of Florida

We are using Cellometer to do cell count and RFP, GFP readings. It is very easy to find transfection efficiency of transfected cell lines using Cellometer. Saving time in cell counting also. Very fast and gives dilution calculations, that is also a very good tool. - Lata Chuhan, University of Florida

The Cellometer has been one of the best equipment buys in a long time.  Very efficient and accurate for our purpose and it fits perfectly in our TC room and on top, it is very easy to use.  The lab is very happy with the machine.

The Cellometer instrument has made counting cells and assessing viability fast, accurate and very easy to do. I am able to keep better track of my cells because of it

The Cellometer has made banking our cells lines much easier, and with easy data collection that includes viability. Previously, time was a major factor in if we count cell lines before banking, but now it is easy enough it can be done no matter what.

I have had very good customer service with Nexcelom. We had a live remote demo of compliant software add on and continue to be in contact with the QA software application specialists.

The Cellometer has been highly welcomed in our lab. Research associates and post-docs are happier having this quick and effective method of cell counting. It really saves a lot of time and it's so easy to use!

The Cellometer has saved hours in research, which I put towards more productive experiments.

We have been using this machine for the past two years and it's much more efficient and saves our researchers a great deal of time

The Cellometer saves me so much time!

Your Cellometer instrument makes it easy for us to quantify the survival of yeast cells. This instrument literally saves us hours per week. Thank you Nexcelom! - James Ritch, Providence College, Biology Dept

It's so fast and easy. I have to count many cells, what would normally take forever. The Cellometer gives me accurate counts within almost no time!

We process individual spleens from multiple mice. As such, we count each cell preparation separately. After isolating T cells using magnetic selection, we have to count them individually again! Our Cellometer is likely the most used piece of equipment in our lab and works every time. It has dramatically reduced our counting time, as well as increased the accuracy of our viability tests. - Jerid Robinson, Emory

I love how quick it is. Especially when I'm platting a bunch of cell lines at once.

We purchased a Cellometer a few months ago and have been very pleased with the device. We are able to accurately count WBC in our products even those with low cell numbers and obtain an accurate viability all very quickly. This device has replaced our hematology analyzer for several applications and we have recommended it to several others. - Amanda Medcalf, Fate thereapeutics

Using the Cellometer to count cells has saved me a LOT of time and energy in the lab. Especially since I don't have a human assistant having a mechanical assistant give me time to focus on other tasks. - Ranor Basa, Vala Sciences Inc R&D

We're using Cellometer Auto1000 for regular cell counting. Now it becomes so easy to do this. Just with seconds, it's done. Great instrument!

Used Cellometer to count zebra fish chondrocytes. This was so easy and convenient to use.

The Cellometer allows me to count my cells quickly and effectively. I have saved so much time switching from manual cell counting to an automated cell counting system.

The Cellometer is a huge time saver compared to using the hemocytometer.  In addition, with undergraduate and pharmacy students, the Cellometer eliminates the variation in the results that is sometimes seen.

Getting the Cellometer Auto X4 for algae counts has helped us tremendously. We use algae to feed freshwater mussels and it is very difficult to determine how much food they are receiving if the algae count is unknown. With this machine, we are able to check all of our mussel culture waters in less than 30 minutes!

Our Lab uses Cellometer on a daily basis It is so convenient and fast specifically when preforming multiple samples at the same time - Shalu Sharma Kharkwal, Albert Einstein College of Medicine

Our Cellometer allows us to measure concentration and viability of PBMCs in patient blood samples in a fraction of the time it used to take using manual hemocytometers

I have just learned how to use our Cellometer this past week and was amazed at how intuitive the software is. The slides were also very easy to load.

The Cellometer cell counter has made cell counting so much faster and very easy. It is much more efficient when harvesting cell samples to quickly count multiple samples at once, with great accuracy, and allows us to start seeding cells at optimal densities much quicker than before. This was cells are not sitting in tubes for long periods prior to plating, causing them less stress. Thank you Nexcelom!

Outstanding instrument. Easy to use and accurate results - Sumi Dinda, Oakland University

X1 is easy to use accurate fast, Viability and cell count in 1 step is fantastic - Jim Elliott, Captain Lawrence Brewing

The Nexcelom Cellometer allows my research team to accurately and efficiently count even more cells - Avelina Espinosa, Roger Williams University

We use the Cellometer for all of our cell counts! It is especially important for clumpy difficult to dissociate lines - David Esopi, Johns Hopkins University

For cell lines in particular (and 'clean' cells) counting is much, much easier and get a lot more stats. However do need to let the cells settle for 15-30 seconds prior to counting. Also still working on learning all the menu items. But an excellent addition to the lab. - Nicholas Lanson, LSU Health Sciences Ctr

Ability to distinguish viability from vitality as well as avoiding error prone plate counting to determine cell concentrations. Previously we'd have very different cell count results person to person, now the method is more standardized along with the ability to go back and correct counts if necessary (eg. better documentation).

It makes counting PBMC's from serum really fast, so when I have to plate from 18 different samples it doesn't take as long as a hemocytometer would! - Jennifer Arab, CSU

It is very efficient, accurate and a time saving instrument.

Since I work on cell proliferation I often have to use microscope/hemacytometer chamber for cell counting which has always been a pain for me. It has made it good for my research each week. - Pundrik Jaiswas, NIDDK

Much better tool for quantifying cell growth than luminescent viability assays alone.

The Cellometer Vision is a great product! The instrument is quick and easy to learn to use, and the software is very user friendly. We have used our Cellometer device to obtain data that we would normally have to use the flow cytometry facilities to get. The machine has made of number of data types both inexpensive and quick to obtain. In addition to the product itself, the customer service we have received is excellent - only adding to the quality of the product!

Cellometer is very easy to use. The fact that it can be used with AOPI and eliminate the count of erythrocytes is very convenient. It saves a lot of time to use the Cellometer instead of manual counting, and it allows me to keep on working on other stuff while the cells are being counted. - Maria Agarwal, Johns Hopkins University

It has made my cell counting much more reliable, and much easier, at the same time. The ability to alter the settings towards your specific cell type are critical as well.

Transitioning to the Nexcelom Cellometer from our previous method using Flow Cytometry, has been smooth and efficient with the help of the great team at Nexcelom support. The software is very user friendly and the instrument is maintenance free. I would highly recommend the Nexcelom Cellometer K2 to other facilities looking to use image-based cell counting systems.

The Cellometer K2 instrument is a simple, quick, visual cell counting platform. We love the clear images and easily discerned confirmation that the cell count data is real because you can see the count with your own two eyes. It has allowed us to move away from difficult flow cytometer and subjective hemocytometer methods.

I enjoy using our Cellometer especially on high volume processing days. It's simple to use and gives data that is needed and quite essential for result reporting. Use is not intimidating at all.

The ability to record the image of the counted cells together with the cell size distribution data in TBE assay. Also, to be able to set up the range of the cell size for counting.

The accuracy is outstanding; our 30 minute cell-counting time has been reduced to less than five minutes; furthermore, the viability assessment of the cells being integrated into this system has made our experiments much more efficient.

Allows me work with more cells at a time since counting them now is so easy and fast. If I had to count with a hemocytometer I would probably only work with 1/4th of the cells I do now.

The Cellometer has been a great asset to multiple departments in our company. When looking to move from flow cytometry cell counting methods to microscopy cell counting, we tested many options and settled on the Cellometer. We now use these instruments at two sites and within our manufacturing and QC departments. We are still in our validation phases with the instruments but they will eventually become our primary method for manufacturing and QC. I enjoy using this instrument because there is no setup or shutdown procedures that are needed. You can simply turn it on, use it, and shut it off. So easy!

Our Cellometer instrument is easy to use and is much more efficient than counting cells manually. It increases the throughput in our lab and makes our results more accurate. We love our new instrument.

The Cellometer Slides have streamlined cell counting making it easier and more efficient.

I like the Cellometer Instrument because it allows our lab to count our viability faster than manual counts on microscope. Our count time is only 5 minutes instead of 10 or 15 minutes!

The Cellometer has made my cell line work run more smoothly and efficiently. I love this instrument.

I like my Auto 2000 because it saves my images, so that I may go back and review. I also like the histogram and the ability to export to excel.

Great product! Saves me an hour of eye-straining counting. I count my cells before labeling with antibodies for flow cytometry. Now I can easily double the number of samples I can analyze in one day.

Our Cellometer has made cell counting much faster, easier, and also less operator dependent. It has saved us both time and hassle. It's amazing! - Dan Thoren, Viatar

The Cellometer instrument is simple to use and helps us be more productive - Marcia Lee, OARDC/FAHRP

I have used Auto 2000 in my previous lab extensively for counting mouse primary cells. I can not be thankful enough to you guys to make such a great product. I Liked it so much that I convinced my boss at new lab in FDA to buy Auto 2000 in spite of having a cell counter from different company.

It is simple to use and provides us with accurate cell counts. An absolute time saver in our very busy workday.

The cell proliferation experiments by counting the actual cells has become so easier and quick. - Puspa Raj Pandey, NIH NCI

We are finding it much easier to generate quantitative data that we trust at a rate of progress well beyond what was possible in our lab before by conventional imaging and image analysis approaches. - Rob Bellin, Holy Cross College

The Cellometer allows us to see how many cells are in suspension for each fermentation test we run. This has changed how we work from an OD reading to actual cell counts.

We love the product and use the Cellometer every day to count cells.

The Cellometer instrument gives a quick and easy way to count individual cells and also increases the throughput and efficiency compared to manual counting. I am working with 200 different clones that needed to be counted and I was able to get the cell count, concentration and %viability in a fairly short period of time! If I had not used the Cellometer Auto T4 cell counter, I would most likely not have been able to finish counting cells from each clone. Manual counting would have been extremely time-consuming and I would be particularly concerned with miscount errors that affect the accuracy of the cell concentrations. All in all, this instrument has definitely been a life saver for me!

Using the Cellometer Auto 2000 has been a walk in the park! The instrument is flawless and the digital display is exquisite! This machine has saved me so much time and has allowed me to complete all my work in a timely fashion. Thanks guys! Keep up the good work! - Dylan Johnson, Burleson Research Technologies

Compared with Countess that I have used before, Cellometer provides me with more easily accessible information about the cells, not only just some numbers although those numbers are the ultimate goals. It makes me trust the data generated by Cellometer more when I can see my cells at different views on the computer just like I am looking at them under a microscope and you get to manually focus on the cells.

The Cellometer has allowed our lab to perform experiments that would have otherwise been impossible to do without expensive equipment and/or core facilities. It has also allowed us to expand our research projects due to the availability of experiments within its protocol library as well as its ease of use. The Cellometer, along with its FCS software, has made data collection an easy task as the program allows the user maximum control over all experiment parameters.

Cellometer is a much faster convenient tool to do cell counting. It releases me from the tedious boring cell counting work and saves time; 20 minutes counting by myself and only 1 minute using Cellometer.

The amount of time we save by using the Cellometer has changed the output efficiency of our lab. I especially appreciate the user friendly setup and the ability to recall saved profiles, so that we do not have to spend time providing cell type and diameter information before each count.

The Cellometer has sped up our lab's cell culture workflow greatly as it counts much more rapidly than other counting machines we have tried. We also like the intuitive software and ability to create custom profiles that we can save for each cell line. - Kyle Johnson, The Translational Genomics Research Institute

The instrument was pivotal in my experiment of measuring the percent of cells expressing GFP fluorescence. The associated software was very helpful in understanding my results; being able to view the data as histograms and in a tabulated form was very useful.

Reduced my work time by several hours! Gave me accurate results! - Pushpak Bhandari, Purdue University

We have improved our counting accuracy of Entamoeba cells for inhibition assays and shortened our time in counting cells.- Avelina Espinosa, Roger Willliams University

Easy to use and accurate. The software also is pretty straightforward and simple.

It's been very convenient for me to count cells using this pure automatic Cellometer; I love the fast output and USB port.

Cellometer Instrument makes our routine experiments faster and easier, since a lot of our assays require a specific number of cells, with the counter we have better, accurate and reproducible results.

Our lab purchased a Cellometer Auto 1000 a year ago, and it has been a great pleasure ever since. Cell counting that could take a half-day to do using the hemocytometer takes only half an hour. Besides, viability test and size measurement also becomes very simple and easy. This auto cell counter really increased the efficiency and accuracy of our cell counting. - Zhe Zhang, MIT

It makes cell counting easy and accurate! - Jeff Leong, Washington University

We used to count cells by hemocytometer, which was tedious and low throughput. We're now able to use a much smaller amount of sample to obtain reliable cell counts. It has also helped accelerate our work assessing cell viability, under different stressors.

The Cellometer prevents direct use of the microscope. This is more convenient and comfortable for the user to assess the pictures taken by Cellometer rather than straining over the scope. Also, since the machine is hooked up to the computer, it has many more options for data analysis and manipulation. - Juhyun Lee, Emory University

The Cellometer has made counting cells easier and more efficient. Before we got our Cellometer, I would spend hours at the microscope straining my eyes to count cells. Now counting has become quicker and less tedious. We usually just do trypan blue counting but occasionally we use AOPI to get a more accurate live/dead count for tiny cells. The software is very user friendly and the technical support is excellent.

The AO/PI Yeast Viability Kit containing dilution buffer and fluorescent dye mixture for staining of live and dead Yeast cells makes counting yeast cells incredibly simple! WE LOVE IT!!

We love the speed and efficiency of the Cellometer. It makes our proliferation curves easy instead of tedious! - Tasha Pontifex, University of Arizona

The Cellometer has proven to be a practical and efficient means of obtaining both cell counts and viabilities on flow cytometry specimens. We are able to easily test lysed and unlysed bone marrow aspirates and peripheral bloods, as well as tissue samples, needle cores biopsies, and body fluids. Utilization of the large depth counting chambers has even made it possible to perform counts on low volume/low cell specimens. Overall, we are extremely pleased with the addition of the instrument to our laboratory.

It saves precious time counting cells, and has more functionality and accuracy than manual counting methods. - Maura Diamond, CHOP

The Cellometer has made counting so much easier that we are now able to up the number of samples for experiments. Before it, we would have to factor in over an hour to count samples by hand but with the Cellometer we can isolate 4-5 tissues from a mouse and do 7 mice and count all the samples within an hour, something that would take much longer by hand.

The Cellometer has provided a much quicker and easier way of counting cells now. We frequently count cell death frequencies and the option to included or not include these counts is very useful to me. Overall, we are extremely happy with the Cellometer.

Using the Cellometer Auto 2000 is so much easier and faster than what we were doing before. Everyone in the lab is enjoying the instrument and taking full advantage of all its capabilities. We're glad to have the instrument in our facility.

We have the Cellometer Auto 2000. This instrument has streamlined our experiments. We have several animal studies that require various cell counts. Given that these studies take place over several months, the Cellometer has given us a mode by which to keep out counts consistent (as opposed to manual counting, which would require the same person to count over the course of experiments and is relatively subjective anyhow). We love how quickly we can obtain our data and feel confident that the instrument is giving us accurate results. It's also convenient that the Cellometer works with a variety of dyes (AO/PI, Trypan Blue, etc).

Cellometer is fast, precise and easy to use. Moreover, it is adjustable for parameters of many specific cell types.

I love the Cellometer for its accuracy, efficiency, and reliability. It's easy to use and applicable for a wide variety of cell lines, which is extremely useful to our field, and it's changed the way I work because it is a true time-saver. No longer do I have to record absorbances or use a hemocytometer!

2013

Cellometer instrument is easy and fast to use and also give us the accurate cell counts. It is totally changed how we count our live cells in the process for our undergoing and/or ongoing experiments. It only takes minutes to finish what used to taking us hours. We can't imagine to go forward with cell counting without Cellometer.- Xianglan Yao, NHLBI

I also can't say enough wonderful things about the technical support that is offered through Nexcelom. The people are wonderful and always willing to go out of their way to help develop and trouble shoot the assays.

We started using the Cellometer Auto T4 for our counting/viability measurements and it has sped up the process of subculturing considerably. We do multiple flasks at a time and being able to use an automated counter vs. a hemocytometer makes the process much easier. I like the disposable cell slides because there is no need to clean up afterwards, it just goes into the bio waste bin. Overall, we are very satisfied with the Cellometer counter.

My name is Dylan Armes, and since getting a Nexcelom Cellometer my day-to-day work in my lab has become significantly easier. I used to use a different counter, but the ease of use of Nexcelom slides is MUCH more convenient. I primarily use the counter to determine total cell volume in a sample for easier distribution on microscope slides, and it works perfectly for that purpose. It's quick, accurate, and very easy to use. Dylan Armes - Lovelace Respiratory Research Institute

We love our Cellometer! More time for experiments, less time counting your cells. And no more sore thumbs or annoying hemacytometers.
A scientist from the University of Colorado

(Cellometer) relieves the heave work of cell counting, improves the efficiency of counting.
Researcher in Shanghai, China

Just as the Nanodrop changed spectro photometry - forever - in the lab, so has the Cellometer revolutionized cell counting in the tissue culture room. No more Hemacytometer! We also like our Sales Representative, Grace Vick, she is always there for us!!
Senior Scientist from NIH

Counting all of our Insect cell cultures used to take half the morning; now, with our Nexcelom Cellometer, I'm ready to start passaging in just 20 minutes! Thank you! With the added information of average cell diameter, I am able to more accurately predict when my Baculovirus stocks are ready to be harvested. Since the Cellometer is so easy to use, we are sampling our cultures at several additional points in our process, which has improved troubleshooting of process issues. The Cellometer has helped us to cut costs by enabling us to detect failed (virus amplification and protein expression) cultures earlier in the process. Thank you Nexcelom!
Senior Scientist from a Major Life Science Corporation

We bought the Auto T4 in 2007 and love it! I'm able to seed multiple experiments of multiple cell types in such a short time. We told other labs how much we liked it and another bought the newer version of the T4 and others buy the slides and use ours. Thanks!
Denise Hegan, Yale University

It makes counting so much easier. No need to use the hemacytometer! You can still see the cells and do live counts. Great for counting many samples.
Senior Scientist from Boston Scientific

Having this device has streamlined our cell culture work very much. Instead of only being able to count 2 or 4 cell samples at a time, we can set up as many as we need, and have the Cellometer count them. It's much more accurate than hemacytomer counting, and much faster, which is a bonus when we have 15 transfection samples to count! We have a fluorescence capable model, and using it to determine the percentage of transfected eGFP cells is quick and easy, and doesn't entail tedious slide staining on our part. We couldn't live without our Cellometer!
- Kristina Muskiewicz from Forma Therapeutics

Not only is the Cellometer good for counting cells but we also use them to count our MFIA beads. It gives us a more accurate count of the final yield and also cuts the amount of time spent on counting in half.
- Nhu Thao Le from Charles River Lab

I do at least 10-15 (PBMC) samples a day or at a time and it used to take almost 1 hr now with Cellometer it takes almost 8 minutes for all the samples. That's quick, easy and results are fantastic and this spares my eyes a headache. Thanks, Rakesh Sharma
- Rakesh Sharma from MD Anderson

Very useful tool for a cell sorting core. We use it to verify the drop delay setting, troubleshoot sorts by looking at cells for debris or dying cells, double check yield of cells from sorts, and help determine what settings are appropriate to perform a sort.
- Biologist from Harvard Medical Center

Actually being able to visualize overall clumpiness of cells is a major help, using our other cell counter can tend to miss a good majority of cells if they tend to aggregate more. - Biologist from Eisai
