The Invitrogen Countess 3 Automated Cell Counter was developed using an advanced machine-learning image analysis algorithm to deliver accurate cell counts and viability measurements in fewer than 30 seconds. The Countess 3 instrument has automated lighting, focus, capturing, counting, and saving; all you need to do is insert the slide containing a cell sample.
Choose between the disposable Countess Cell Counting Chamber Slide for maximum convenience or the Countess Reusable Slide for sustainability and cost reduction. Enjoy the speed and convenience of automation with superior counting performance.
The Countess 3 instrument shares common features with the Countess 3 FL model: It is accurate, precise, fast, simple, and automated; it offers viability measurement and single-cell data; it is compatible with reusable slides; and it has optional software to support 21 CFR Part 11 compliance for electronic records.
