CellDrop Automated Cell Counters feature patented DirectPipette™ Technology to eliminate plastic slides and cumbersome hemocytometers from routine cell counting. CellDrop Cell Counters feature dual fluorescence and brightfield optics, variable height sample chamber, and powerful, easy-to-use analysis software. The instruments enable the fastest cell counts, viability assessment, and GFP transfection efficiency measurements across the widest range of cell density, cell type and application. The CellDrop Automated Cell Counter Series 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. 10µL 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. CellDrop Cell Counters are a flexible workhorse for the busy, multi-user lab.
