Cell counters are tools for counting live and/or dead cells in a culture. Any researcher who works in a cell culture hood needs some sort of cell counting solution, whether to determine cell concentration prior to cell passage, or to assess cell viability following drug treatment. The C100 from RWD is a perfect cell counting option for any lab and is appropriate for a variety of samples, including mammalian cells, stem cells, blood cells, epithelial cells, endothelial cells, and more.

The RWD automated cell counter uses microscopy with auto-focus technology that analyzes and counts cells in less than 20 seconds. Without requiring user input, the sophisticated cell counting algorithm uses the image acquired to detect cells and omit debris, to provide an accurate total cell count. The auto-focusing feature means all users of this system can expect reproducible cell counts with reduced variability compared to manual hemocytometer counts and cell counters with manual focus.

Smart simple touchscreen functionality 

Easily set up experiments on a 7-inch Capacitive touch screen. The intelligent touch screen interface is designed to provide complete data visibility to monitor all.

Compatible with a broad range of cell sizes and types  

counts cell lines, primary cells (from tissue or blood), and stem cells. Cell sizes can range from 4-60 um.

Modern auto-focus capabilities  

Removes the variation associated with manual focusing and provides precise cell counts less than 20 seconds.

Easily upgradeable fluorescence detection

The RWD Cell Counter offers one brightfield and optional, user-interchangeable fluorescent channels. The fluorescent colors detected are determined by the insertion of individual light cubes. We offer the 3 different cubes covering a wide range of the most commonly used fluorophores. This includes Trypan blue, AO, PI, GFP and DAPI.

Cell viability

Evaluates cells accurately using multifocal plane analysis. Using auto-focus instead of subjective manual focusing is important when evaluating cell viability as an incorrectly selected focal plane will lead to wildly inaccurate results.

Easy to record and analyze at any time

The RWD Cell Counter leads the industry in allowing users to store up to 1000 counts and reports. These can be reviewed whenever the user needs.

What sizes of cells can be counted by the RWD Automated Cell Counter?

Objects of ~4–60 μm can be counted. The optimal range though is cells of ~7–60 μm

can be counted.

How long do the instruments take to count?

~20 seconds per sample.

Can I buy the RWD Cell Counter instrument without fluorescent light cubes?

Yes, it can function as just a brightfield cell counter. Users can easily add light cubes as application needs evolve.

Can the images be saved?

Yes, the results and image files can be saved after each count.

How do I clean and maintain the instrument?

Clean the surface of the instrument with a damp cloth. Wipe the screen dry immediately.

Do I have to calibrate the RWD Cell Counter?

The system comes pre-calibrated and there is no need to recalibrate at anytime.
