Introduction
Product Overview
Countess
™
Automated
Cell Counter
The Countess
™
automated cell counter uses state-of-the-art optics
and image analysis to automate cell counting. The Countess
™
automated cell counter is a benchtop counter designed to measure
cell count and viability (live, dead, and total cells) accurately and
precisely, using the standard trypan blue technique.
Using the same amount of sample that you currently use with the
hemocytometer, the Countess
™
automated cell counter 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.
The Countess
™
automated cell counter offers an intuitive user
interface, and provides the option to save and print cell count data
using the Countess
™
software (download from
www.invitrogen.com/countess) and USB drive supplied with the
instrument or available separately.
The Countess
™
automated cell counter is supplied with disposable
Countess
™
cell counting chamber slides that contain two enclosed
chambers to hold the sample to allow you to measure two different
samples or perform replicates of the same sample. The cell
counting occurs in the central location of the counting chamber
and the volume counted is 0.4 μL, the same as counting four
(1 mm × 1 mm) squares in a standard hemocytometer.
See page viii for details on various parts of the counter.
