Description
The Invitrogen Countess 3 Automated Cell Counter uses an advanced machine-learning image analysis algorithm to deliver accurate cell counts and viability measurements in less than 30 seconds. This Thermo instrument automates key tasks such as lighting, focusing, capturing, counting, and saving, requiring users only to insert the slide containing a cell sample. The Countess 3 is designed for cell culture laboratories that need a fast, simple, accurate, and affordable method for performing brightfield cell counts in preparation for downstream applications or culture splitting.
The Invitrogen cell counter has several key features. It accommodates a single 2-chamber slide, which can be disposable or reusable. The required sample volume is 10 µL, and the sample concentration range is between 1 x 10⁴ and 1 x 10⁷ cells/mL. The Invitrogen Countess 3 has a generous particle/cell diameter range, spanning from 4 µm to 60 µm. The counting area measures 3.82 mm². The automated cell counter is equipped with both on-board and USB memory for data storage, and it features a clear LCD display for viewing results. The Countess 3 cell counter benefits from a a single-channel optic system and comes with a 5-megapixel camera, providing 2.5x optical magnification for precise image capture.
