Description
The Accuris™ E7500 QuadCount™ Automated Cell Counter improves on simple brightfield microscopy with an LED light source, precision optics and a high-resolution CMOS detector. A finely tuned, motorized XYZ stage provides extra-fine focusing and captures multiple images, delivering fast, accurate and reproducible cell counts with as little as 20 seconds per sample.
Compared with tedious manual hemocytometry, QuadCount™ software eliminates human bias in live/dead determination, reduces counting errors and saves time. Advanced detection algorithms correctly analyze irregularly shaped and aggregated cells that are often misinterpreted visually, removing user-to-user variation. A proprietary autofocus system works with the motorized stage to capture images in the proper focal plane — essential for accurate viable-cell counts.
The QuadCount™ uses unique 4-chamber disposable QuadSlides™, processing four samples per slide — twice the capacity of standard 2-chamber slides — to lower consumable costs. Three count modes analyze different sample volumes: Quick (0.15 µl, 1 frame, 20 s), Normal (0.9 µl, 6 frames, 30 s) and Precise (3.6 µl, 24 frames, 100 s). Analyzing larger volumes across multiple frames provides significantly better accuracy.
After capture, gating size range, aggregation level and live/dead definition are easily adjusted on the touch screen, and population statistics are displayed as a histogram for individual or multiple chambers. USB ports connect a printer, external keyboard or flash drive, and detailed PDF reports can be exported for saving or printing. The QuadCount™ is compatible with most common mammalian cell lines, including HeLa, Jurkat T and HCT116.
