Invitrogen™ Countess™ 3 Automated Cell Counter

Description

The Invitrogen Countess 3 Automated Cell Counter is a compact instrument for rapid cell concentration and viability assessment. It utilizes automated brightfield and dual-channel fluorescence imaging to analyze samples in under 30 seconds. The system is designed to count mammalian cells within a size range of approximately 4 to 60 microns in diameter. Brightfield mode provides total cell counts, while integrated fluorescence channels enable viability determination using common stains like trypan blue or fluorescent viability dyes. Operation involves loading a small sample volume into a disposable slide, which is then inserted into the instrument for automated imaging and analysis. Results for cell concentration and viability percentage are displayed on the screen, streamlining routine cell culture workflows and reducing user-to-user variability associated with manual counting methods.
