Powerful, Intuitive Software
Results
CellDrop results include a wide range of application-specific metrics for each cell sample. Data is clearly displayed on-screen and auto-saved to a large onboard hard drive. Metrics include:
Graphical Data Display
A wide range of graph types are available to gain additional sample insight. Overlay multiple samples from the same session or from the data archive for powerful data visualization.
Dilution Calculator
The convenient dilution calculator automatically calculates target dilution volumes of cell culture and buffer based on each cell count. Dilution guidance is displayed prominently on-screen and in printed reports for easy sample processing.
EasyApps™ Software
CellDrop EasyApps software is designed by life scientists, for life scientists. The system features a high definition, 7″ touchscreen and pre-installed apps for a range of common applications.
Additional apps for accounts, data, and other utilities contribute to the system’s easy-to-use interface.

- Use as a starting point for your sample, or reach out to our applications team
Controls Toolbar
- Name sample
- Choose protocol
- Exposure
- Focus (includes Autofocus)
- Fluorescence channel selector
- Dilution calculator
Autofocus
Setting the focus on the CellDrop is easy. Because of the CellDrop’s fixed sample surfaces, adjusting focus is not often needed once it has been set. However, the software is also equipped with Autofocus. Just press the Auto button in the focus menu to automatically adjust to the correct focus.
Cell Size Gating
Cell / Nuclei Size Histograms allow easy gating for non-target cells or cell debris. Simply drag the slider to set the cell size of interest and view the results in real time. Results are instantly re-calculated excluding all debris or cells that fall outside of the defined size range
GFP Intensity Gating
When using the dedicated GFP App, users can gate cells by fluorescence intensity as well as size. The intensity histogram displays the number of cells counted at each GFP intensity level allowing the exclusion of non-GFP expressing cells or low expressing cells to be excluded from analysis.
Advanced Declustering Algorithms
All CellDrop Count Apps use proprietary declustering algorithms developed by DeNovix. Complex samples of regular or irregular cells over a wide range of cell density can be rapidly and accurately counted. Analysis of cluster size and frequency can be performed and graphically displayed.
Irregular Cell Mode
For cells that are elongated or irregularly shaped, enable Irregular Cell Mode from the Protocol Settings or the Optimize Setting button on the results screen. This is ideal for cells that are not round when trypsinized, such as fibroblasts or epithelial cells with a high degree of structure.
Irregular Cell Mode is also used to identify irregularly shaped isolated nuclei, such as smooth muscle nuclei from heart tissue.
IQ/OQ
A full installation and qualification (IQ/OQ) package is available for the CellDrop Automated Cell Counter.
Performance Verification Slide
The performance verification slide is a slide with beads fixed on the surface and is designed for assessing the accuracy and precision of a CellDrop Automated Cell Counter. Each slide includes a factory-certified value for the number of beads on the slide. Technical Note 224 provides instructions and calculation tables for validation.

Allison Cote
Using DeNovix CellDrop for almost a year I have had the best experience with it - easy-to-use interface, high quality camera, lots of built-in applications, almost no maintenance and of course no need to use cartridges or slides. Highly recommend to anyone looking for a good and reliable automatic cell counter.
Andrey Gorin
This one is a game-changer! If you haven't used one yet, you are missing out on a great equipment for your otherwise tedious and inaccurate cell counting. The FL method is by far the best way to do this. I couldn't be happier!
Rushita Bagchi
Coming from hand-counting cells, using the CellDrop has vastly improved my research by greatly saving me time. Plus, the user interface is very easy to use and learn. Getting to save counting protocols is great too. Overall, I would greatly recommend.
Austin Santhin
Simple to use and accurate, reduces waste and has a small footprint. After sales service is excellent.
Gillian Kay
Highly recommend for quick and accurate counts. Very pleased with this cell counter! Compact for benchtop and easy to use with no consumables needed. Excellent customer service and guidance whenever required.
Sara Silk
CellDrop is a great cell counter! This cell counter replaced our older Countess Cell Counter and is easier to use and more accurate. We are a 20+ person lab and the CellDrop gets used often with no issues thus far. Highly recommend this product.
