In Nexcelom’s long line of automated cell counters, there is one instrument designed specifically with your budget in mind – the Cellometer Mini! As the lowest-cost cell counter on the market, it utilizes bright field imaging, and is perfect for any lab looking to achieve basic cell count, concentration and Trypan Blue viability of cultured cell lines and purified primary samples. It’s affordable, accurate, and small enough to fit in your purse or backpack! Need a little convincing?  Don’t just take our word for it, here’s what our customers have to say:

Celloemter Mini Bright Field Cell Counter

“The Cellometer Mini is such a time saver compared to using the hemacytometer! We love it and use it all the time. It is easy for students and residents to use, which also saves us in training time.” – Southeast HSC

“The Cellometer Mini is incredibly rapid at counting cells. Even better, the software has a built-in calculator for determining dilutions. It speeds up our workflow.” – Baylor University

“The Cellometer is quick and convenient and I find the cell counts to be just as reliable as using a hemacytometer. My lab cultures several different cell lines and we save hours by substituting the Cellometer for the hemacytometer! I have trained my students in my cell lab to use the Cellometer and they now spend less time counting cells and have more time to do experiments!” – Wheeling Jesuit University

“I really appreciate the small footprint of the Cellometer Mini. It doesn’t take up much space and it is very easy to use. The guides provided make it a no-brainer!” – Leidos Biomedical Research

 

The Mini is user-friendly and fast, without sacrificing accuracy with its low cost. The instrument you want is obtainable on a budget!  Contact us if you are interested in a quote, scheduling a free in-lab demo, or speaking with a specialist.

Do you rely on a Flow Cytometer? Want to break free?

Sara Barker | February 15, 2017 | No Comments | About Cell-Based Assays

If you rely on a flow cytometer in a core lab or a central facilities lab, have you ever wondered if there was a better way? Have you ever wished to have full control over your experiments, rather than hand your sample over to a technician?  There was an interesting article written recently about the needs of researchers. Have you seen this?

Those interviewed for the article suggest that there are some main factors for consideration:

  • The instrument size needs a smaller footprint than existing products offer
  • The price of the instrument should be under $100,000
  • Software ease-of-use to reduce the need for dedicated technicians
  • How many colors/markers are needed

If you’re open to an alternative to flow cytometry, we would suggest you consider image cytometry. It is what it sounds like. It performs assays and experiments like a flow, but there are no fluidics, just images. That means no clogging. No cleaning. No calibration. No maintenance. No headaches and no hassles!

Consider the Cellometer Vision CBA. The footprint is compact – 6″ wide x 8.5″ deep and 14″ high. The US price is less than half the standard budgets for a benchtop flow cytometer. The Cellometer software is designed to be intuitive, easy to use, and easy to customize; and if you aren’t fully confident, we have free support – both on-site and remote. The system is able to analyze 2 colors at a time, and with interchangeable filter optics modules, you have flexibility on the markers you use from experiment to experiment. If you need to sort your cells, this wouldn’t be your ideal instrument. But if you want to break free from the flow cytometer – request a quote or talk to a local scientist about setting up a free in-lab demo to see if for yourself.

Ever lose count when manually counting?

Sara Barker | January 19, 2017 | No Comments | About Cells

If you’re using a microscope and hemacytometer to count your cells and determine viability, you might have felt like Sheldon, when he vacations in Amy’s lab and, among other things, helps out by counting the bacteria spores.  Everything’s going well until Amy returns to the lab, distracts Sheldon, and then he has to start over with his count.

Fortunately for you, you don’t have to be like Sheldon if you have an automated cell counter. We have bright field counters for cultured cells and Trypan Blue exclusion assays. We have dual fluorescent cell counters for messy, primary samples that are great with a nuclear stain such as Acridine Orange (AO) and Propidium Iodide (PI). We also have image cytometry systems, giving you the power to perform cell based assays such as apoptosis, GFP/RFP Transfection, cell cycle, autophagy, mitochondrial potential, etc, with only 20 microliters of sample. All of our systems will take images and analyze the sample in less than a minute – with most systems completing in less than 30 seconds!  Our systems can image and analyze cells as small as 0.5 microns up to as large as 300 microns in size!

Check us out – request a free on-site demo, or ask for an evaluation unit that you can try and use in your lab for a week – at no cost.

Having a tough time counting your PBMCs?

Aimee DesRoches | January 3, 2017 | No Comments | About Cells

If you are experiencing difficulty counting your PBMCs with Trypan Blue using a hemacytometer, we feel your pain! But did you know all that pain can be avoided? With the Cellometer Auto 2000 automated cell counter, counting peripheral blood mononuclear cells (PBMCs) and other complex primary samples is a breeze! Using dual fluorescence image-based cytometry and staining your samples with AO/PI (acridine orange and propidium iodide), the Cellometer Auto 2000 cell counter can detect live and dead nucleated cells while excluding debris, red blood cells, platelets in your sample. Here is what some of our happy customers counting PBMCs have to say:

 

“My colleague and I have purchased a Cellometer Auto 2000 cell counter. We are using it now and it has facilitated our work greatly. We routinely process PBMCs from both fresh whole blood and from frozen stock. The Cellometer has made it much easier to get cell numbers and viability percentages for use in downstream applications such as IVS and Elispot.”  – Human Longevity, Inc.

 

“The Cellometer 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!”  – Colorado State University

 

“The Cellometer Auto 2000 makes cell counting much faster and more accurate than manual counting.  Our laboratory needs to complete splenocyte and PBMC isolation protocols as quickly as possible, and the Cellometer allows us to count samples from 6 isolation batches in about 15 minutes.  This gives us the ability to isolate more cells at a time, because we know they will not be sitting too long before we have a final count.”  –   Academic Research Laboratory

 

“Our Cellometer is an important asset to the work we do in our lab, specifically PBMC isolation. No common cell counter has the capacity to count PBMCs. We love the portability of the instrument (due to its small size) along with being able to see the cells on the screen and the extra features – such as sorting data, printout capability, and aliquot calculations. Truly a fantastic investment!” – Leading comprehensive cancer center lab

 

The Cellometer Auto 2000 can also be used for counting stem cells, splenocytes, irregular-shaped cells, messy and clean samples!  Forget the hassle of red blood cell (RBC) contamination, broken hemacytometers, and inaccurate counts – as one of our fluorescent automated cell counters may be a great addition to your lab! We offer free in-lab evaluations of the Auto 2000, so if you’d like to try one for yourself – fill this form out!

Benefits of direct high-throughput cell counting in immuno-oncology research

Sara Barker | October 27, 2016 | No Comments | Celigo Application News

Antibody-directed and drug therapies have been on the forefront of immuno-oncology research in the past 15 years. Since the FDA introduced the Breakthrough Therapy Designation in 2016 for novel promising drug therapies, the number of applicants and approved candidates has increased dramatically.

As more and more researchers are looking at drug effects in cancer cells and moving forward in drug discovery, they face many challenges in their day to do work. Performing cell cytotoxicity assays for multiple cell lines with single and combination drug therapies is standard practice in immuno-oncology. While many researches use end-point assays such as MTT, XTT, WST, or CellTiter-Glo, others prefer the manual counting using Trypan Blue. While these methods may be popular,  it does not mean they are without their limitations. By directly imaging and counting every cell in a well over a course of a drug treatment, the Celigo can perform the cytotoxicity assays in a label-free format.

Benefits of direct high-throughput cell counting in immuno-oncology research

We recently presented an informational webinar on this very topic. If you’re intrigued to learn what advantages and disadvantages we identified for these methods, we encourage you to watch the webinar. You can access it here.

Once you’ve had a chance to watch it, we’d love to hear your thoughts, opinions, and any questions you may have.

Cure cancer… and brew better beer with Cellometer

Sara Barker | September 23, 2016 | 2 Comments | Cellometer Product News

Cape May Brewery

Nexcelom has been using a slogan for the past few years – Better tools for better biology for better life. We manufacture better tools (Cellometer & Celigo) that help researchers perform better biology (cell counts, viability, drug discovery, cell-based assays, etc…) which leads to advances in science and better life for everyone involved! When we were coming up with the slogan, we were going to finish the third part to read “for better science” – but one of our customer groups are breweries (yeast are cells, too!)  – and we didn’t want to exclude such an important group.

One of our newest brewery customers is Cape May Brewing Company, in Cape May, NJ.  Like many of our customers, they didn’t just decide to purchase the instrument. Instead, they first took us up on our Free, In-Lab Evaluation program. (It’s typically for a week, but we often extend it as requested by customers.) It’s a simple process: we ship the instrument, software and some starter materials, we get the users trained and confident in using the instrument, and the end user plays with it for a week – to really see how it performs on a day-in, day-out routine.

Cellometer X2 from Nexcelom

After evaluating our Cellometer X2, Cape May loved it so much, they decided to purchase. And they are so excited about their Cellometer, they wrote an awesome post about it on their blog. Check that out here! (We loved their blog post so much, we’re talking about their blog post in our blog post!)  They sum up the purpose of the instrument in a really great way – “In the simplest terms and the most convenient definition: it’s a piece of machinery that counts cells”  They have even begun to think of what to name it. “[W]e’re thinking of calling CeeLo”  

If you’re interested in learning more about our Free Evaluation Program – check out our webpage for the simple forms we’ll need from you, and then our Support team will be in touch to confirm the details with you.  And Cape May – we think CeeLo is a great name for your X2!

Celigo 5 Channel system officially released

Sara Barker | September 8, 2016 | No Comments | Celigo Application News

Lawrence, Massachusetts – September, 2016 – Nexcelom Bioscience, a leading provider of cell counting and analysis products for biomedical research and the biopharma industry, announced it has released the addition of a 5th channel available as an option on the Celigo image cytometer. The Celigo is a bench-top image cytometry system providing whole-well imaging and quantitative data, through image analysis for demanding cell-based analytical applications. Previous configurations allowed bright field only imaging, or bright field imaging plus 3 fluorescent channels. This new option of bright field plus 4 fluorescent (red, green, blue and far-red) channels will allow researchers more capabilities without having to compromise their assays.

This addition to the product offering was driven by the requests of researchers and current customers. Researchers now use the Celigo image cytometer to develop cell-based assays with cells expressing GFP and RFP in combination with blue and far-red dyes. The other configuration options will still be available for order – allowing researchers to customize the Celigo to best meet their needs.

“The addition of a 5th fluorescent channel on the Celigo responds to the increasingly wider array of fluorescent reagents for cell-based assays available to researchers today and provides our customers with additional multiplexing capabilities for the acquisition and analysis of more complex cell populations.” said Olivier Déry, Director of Celigo Business at Nexcelom Bioscience.

The Celigo allows users to perform high-speed, fully automated imaging and quantification of a wide range of cell types across complex sample types. It enables an extensive menu of applications, and with the option to have it configured with bright field and four fluorescent channels will open up greater possibilities for its use and applications within fields such as immuno-oncology, drug discovery and many others.

Is Automated Counting Right for You?

Sara Barker | March 10, 2016 | No Comments | General Discussions

Our founder, Dr. Jean Qiu, developed the Cellometer Auto T4 in 2005 after receiving a request for such an instrument from a customer at NIH, and we officially launched it at AACR 2006.  As we come up on the 10 year anniversary of the original launch of our first automated cell counter it got us thinking. When we created the first automated cell counter, we created the market for such devices and we were alone in the equipment space for 2-3 years before any other company came out with competitive products. (Imitation is the highest form of flattery, right?)  It was common to hear early on from potential customers, “Why do I need an automated counter? I’ve graduate students to count our cells.”  It’s probably one of objections we still hear fairly frequently. Coupled with that, it always amazes us when we come across potential customers who had no idea there was even any other option aside from manually counting cells with a hemacytomer.

 

We started gathering feedback from our Cellometer users in 2012 and we love hearing from them. If you’re wondering if an automated cell counter is right for you, we suggest you check out why our current customers use and love the Cellometer instruments.

 

One of our first comments on file came from the University of Chicago in 2012:

“The Cellometer has decreased the time spent counting cells significantly. We can isolate cells from 30+ mice and instead of spending over an hour counting cells, we can have it done in duplicate in half the time. This means our experiments can be done how we want them to be done instead of worrying about splitting them into two days because of the time cells would end up just sitting on ice waiting to be plated. For a bigger lab this wouldn’t be an issue, but for a smaller lab of 3 people, the extra time saved makes the experiments run much smoother.”

 

In 2013 we received feedback from a user at the Washington University in St. Louis:

“My colleagues really love the easy use of the Nexcelom Cellometer. It has been a lifesaver from the hemacytometer. We are actually thinking about purchasing a new machine for backup. We are very happy with this instrument.”

 

Feedback really accumulated starting in 2014 when we were receiving comments twice a week. While we never aimed to make “sexy” instruments- instead preferring they were sturdy and robust, it was flattering to receive the following note from North Carolina State University users:

“Using the Cellometer Auto 2000 has been an exhilarating experience. From the ease of use to accurate results, there is not a bad thing to be said about this fine piece of equipment. The focus buttons are extremely responsive and have a great tactile feel. Plus, the Cellometer Auto 2000’s sleek silver exterior is easy on the eyes.”  

 

The Translational Genomics Research Institute shared:

“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.”  

 

Hanger 24 reported:

“The Nexelcom Cellometer X2 has made our daily cell counts and cellar reports much faster and easier. The software interface and sample prep is easy to perform and give consistent, reliable data.”

 

Multiple researchers at Florida State University College of Medicine shared:

“Using the Cellometer Vision CBA has saved me so much time! I am able to get consistent viability data with much less time spent on sample preparation. It has also been great to complete cell cycle analyses without using FACS.”

“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 the our Cellometer 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!”

 

University of Virginia sent in the following praise:

“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.”

 

One of our customers is a regenerative medicine company and we’ve heard back from multiple users there:

“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 from Nexcelom. 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 their is no setup or shutdown procedures that are needed. You can simply turn it on, use it, and shut it off. So easy!”

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

“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 love from our customers kept increasing in 2015 and now, in 2016, we’re receiving comments and feedback on a nearly daily basis.  It’s a great feeling to know the products we delivered over 10 years ago are still in the field. It’s an even better feeling knowing that those same instruments are not tucked away in a closet, but are still being used and aiding researchers.

If you’re considering an automated cell counter system – you’ve many options to choose from these days. You can reach out to us and we’ll tell you why we think a Cellometer is a great option for you – or you can ask to speak with some of our current customers, and they can share their experiences with Cellometer and with Nexcelom.  They are our best advocates and we certainly love our customers.
