My principle application is the routine counting of peripheral blood mononuclear cells (PBMCs). Our laboratory supports phase one cancer research and PBMCs are the preferred surrogate tissue to assess chemotherapeutic activity for time course studies. We have been measuring PBMCs using a Coulter Z1 particle counter. Unfortunately, red blood cells (RBCs) significantly interfere with this instrument and vary widely between patients. Knowing that pre-analytical steps are often considered to be less important than the ensuing technical aspects of bioanalytical methods and are often insufficiently investigated and thus, underestimated. Also, realizing that pre-analytical variables can significantly impact the reliability of our biomarker measurements; and that standardizing specimen collection, handling, processing, and storage methods definitely minimize pre-analytical errors. The K2 offers a solution to the inaccuracy of RBC interference without a Coulter counter and is greatly preferred to the time-consuming manually counting PBMCs with a hemacytometer. - Ken Czambel, The Universitry of Pittsburgh Cancer Institute

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 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.

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.

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!

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.

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

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

The Cellometer is very easy to use and yet is a powerful tool to have in the lab. In addition, the software interface is very user friendly. - Biologist from Bristol Myers Squibb

My company has 2 Cellometers. We rely on them every day to get a quick and accurate count on the many cell lines we have in culture. It is very reliable, low maintenance and saves us so much time vs. hand counting, so we can do our cell work more efficiently. It's a great product. - Tina Glyptis from Forma Therapeutics

Cellometer has saved me precious time, especially when dealing with experiments that are time point dependent. - Deepak Nagendra from Michigan State University College of Human Medicine

The Auto T4 is a fantastic machine that saves our lab a lot of time! It is simple to use and small. - Dr. J. W. Hodge, Senior Scientist and Director, Recombinant Vaccine Group, NCI

I like that this one does not require any other material other than the slides. - Jim Bensen, Tissue Culture Facility, Lineberger Comprehensive Cancer Center, University of North Carolina, Chapel Hill

"I will never use a hemacytometer again" - Jeff Ross, Research Investigator, Eisai Research Institute

"Before the counter it took a long time to count and put strain on our eyes. Now it is quick and very easy on the eyes " - Adam Wiles, Rebecca Shoemaker, AIDS Vaccine Program, NCI

"Using the Auto T4 has greatly increased the efficiency and ease of counting cells in our lab, especially on high volume sample days. It is the only counter that consistently works for non-human primate applications"
- A scientist, National Cancer Institute

"Before it would take 2-3 hours to count-now less than 20 minutes " - A scientist, National Cancer Institute

"Eye strain was a big problem before the counter. It is much faster now and eliminates the eye strain "
- A scientist, National Cancer Institute

"I've used hemacytometer before. It can never get accurate nor consistent cell concentrations. At one time, when I need to estimate the cell doubling time, this counter really helped because I have to deal with multiple cell counting from replicate samples" - A scientist, National Institute of Health

"This is the product I have always dreamed about!" - A researcher, National Institute of Health

"This is such a simple machine to use that it saves us a lot of time." A scientist, Wyeth
