Invitrogen Countess Automated Cell Counter
The Countess automated cell counter is designed to measure cell count and viability (live, dead, and total cells) accurately and precisely, using the standard trypan blue technique. The Invitrogen Countess takes less than a minute per sample for a typical cell count and is compatible with a wide variety of eukaryotic cells and provides information on cell size. A single, sample measurement within a minute provides live and dead cell concentration/mL, total cell concentration/mL, percentage viability, mean diameter, cell images, and a graphical data representation. Cell concentration can range from 1 x 104 to 1 x 107 with sizes ranging from 5 μm to 60 μm. The cell counting occurs in the central location of the counting chamber and uses disposable counting chamber slides that eliminate washing steps and cross contamination between samples.
All of the equipment we sell is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
