CellDrop™ Cell Counters

DirectPipette™ Technology
DirectPipette™ technology eliminates plastic slides and cumbersome hemocytometers from routine cell counting by adding a simple Load, Count, and Wipe Clean workflow. Featuring dual fluorescence and brightfield optics, variable height sample chamber, and powerful, easy-to-use analysis software, the CellDrop enables the fastest cell counts, viability assessment, and GFP transfection efficiency measurements across the widest range of cell density, cell type, and application.

The CellDrop brings the familiar Load, Measure & Wipe Clean functionality of microvolume spectrophotometers to cell counting. Traditional plastic slides or glass hemocytometers are replaced by two permanent optical sapphire surfaces. These are positioned parallel to one another by a calibration-free, high-precision mechanism, forming a chamber of precisely defined height. 10 µL of cell suspension is pipetted into the chamber, analyzed and simply wiped away with a dry laboratory wipe. The powerful live-view image allows instant verification that cleaning has been successful.

Accurate Across the Widest Range of Cell Size and Density
Using conventional counting methods, samples with high or low cell densities require time consuming dilution or concentration steps. The variable height chamber of the CellDrop allows for accurate counts over the widest cell densities - 7.0 x 10e2 to 2.5 x 10e7 cells/mL. Chamber height can also be adjusted to accommodate almost any cell with a diameter range of 4 to 400µm.

Easy-to-Learn, Powerful-to-Use
Designed by life scientists, the CellDrop EasyApps™ software exceeds the functionality of high cost cell counters while delivering the ease of use of simpler systems. EasyApps combines with a high definition, 7″ touchscreen interface to give error-free operation with sample loading to data exporting in seconds. Pre-installed with a range of common applications for one-touch analysis of assays such as Brightfield, Trypan blue, AO/PI, GFP, Yeast, and nuclei—as well as the ability to create custom methods—makes the CellDrop a flexible workhorse for the busy, multi-user lab.

The First ACT® Label Certified Automated Cell Counter
The CellDrop has achieved ACT® Environmental Impact Factor Label certification from My Green Lab®, making it the first automated cell counter accredited by the program. The CellDrop eliminates plastic slides from cell counting workflows, saving millions of single-use plastics every year. The instrument’s minimal energy consumption, recyclable packaging, and estimated 10+ year lifetime also contribute to its low environmental impact.

21 CFR Part 11 Compliance Ready
EasyApps Secure provides an optional suite of software controls that allow regulated GxP facilities to easily add CellDrop to their cell counting workflow (view the compliance statement). The software is fully integrated within the on-board operating system and includes a range of features essential to ensuring compliance, including:

• Password protected system access
• Integrated electronic signature controls
• Comprehensive user account management
• Secure audit trail recording
• Advanced data handling and export tools

Hazardous Samples?
The small footprint and onboard processing of CellDrop allow it to fit inside most flow hoods where required. For applications that require the cells to be contained when reading, all instruments also have the ability to read samples in common disposable plastic slides and reusable slides without the need for additional adaptors.

Models
Available in Dual Fluorescence and Brightfield (CellDrop FL) or Brightfield (CellDrop BF) models.
