View these simple step-by-step instructions for counting cells using a hemoctyometer and microscope. Includes the formula for calculating the dilution factor.
Everyone I meet that performs primary cell counting wants to optimize the amount of time they spend doing that task. They also agree that 30 seconds per count sounds pretty good.
The use of modern automation has largely eliminated many of the hemocytometer's sources of error, increasing the accuracy and efficiency of cell counting today.
Tired of manual cell counting? Let's face it, manual cell counting is tedious. When your day is filled with culturing many cell lines at one time, that's hours of your day just to get the data you need. Not only that, the manual process can be riddled with judgment errors, miscounts, and user-to-user variability. I know what you’re thinking, "You're telling me my hours hunched over a microscope counting cells may not even be producing reliable data?!" Yup. You need a superhero. "So what are my options?" Well, what if there were a powerful superhero that could take a small [...]
How many brewers does it take to count yeast? This sounds like the beginning of a bad joke. In truth, cell counting is really simple but labor intensive & extremely time-consuming. With a Nexcelom Cellometer X2 – it only takes one click & 30 seconds per sample! Cellometer has earned a reputation as the “go to” cell counter for breweries seeking accurate yeast counts, viability & vitality. Just look at the map comparing the distribution of Nexcelom’s Cellometer automated yeast counters and the Top 50 breweries in the US. Data based on beer sales volume adapted from Brewery Association (BA) [...]
As the first automated cell counter ever manufactured, the Auto T4 set the standard with its pattern-recognition software and bright field imaging used to calculate cell count, concentration and viability with Trypan Blue.
...a neck massage! There's a new article out from Biocompare entitled "Cell Counts and More" - and we have to give joke credit to them. We think it's a pretty good one, and accurate, just like our instruments. One of our customers, Tiffany Sidwell, of UCLA Immunogenetics Center, even provided some feedback on the very topic last year. Tiffany shared: "Counting cells daily on the microscope was very bad for my occipital joints and muscles. Since using the Cellometer Auto 2000, I no longer have neck pain when counting cells. Thank you Nexcelom!" There are many, many benefits associated with [...]
STEM - Science, Technology, Engineering and Mathematics - is vital to our future. At present, our students are not stacking up with the other developed countries. We understand the value and importance of encouraging students to explore these STEM fields, and consider a career in a STEM. For that reason, we created a package specifically designed with high schools, colleges and universities in mind. It's called our Teaching Lab - and it has everything a teacher needs to bring automated cell counting technology into their classrooms and labs at a discounted price. The Cellometer Mini and Cellometer Auto 1000 are [...]
https://youtu.be/4xUYjVIgOdQ 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 [...]
Cellometer Auto 2000 cell counter can detect live and dead nucleated cells while excluding debris, red blood cells, platelets in your sample.
