The Invitrogen Countess Cell Counter easily counts live and dead cells accurately and fast – displaying visual results in 30 seconds! The instrument uses Trypan blue staining with image analysis software to provide cell density and viability data for 5-60 um cell populations between 104-107 cells/mL. The unit also houses a dilution calculator to assist with sub-culturing. Instrument consumables may be purchased from the BI.
