Vi-Cell Automated Cell Viability Analyzer
The Vi-Cell S is a single position cell viability analyzer manufactured by Beckman Coulter. The system automates the widely accepted trypan blue dye exclusion method for determination of percent cell viability, cell number and size, and total cell concentration, greatly increasing the accuracy and reliability needed for identical cell plating in multiwell experiments. In addition to being fully automated, other unique features of this analyzer include the broad concentration range (5 x 104 to 1 x 107 cells/ml, a size detection range of 5 – 70 μm, a minimum sample volume of 1.0 ml, an analysis of time of 3.5 minutes, and a 640 x 480 CCD array. The unit is also 21 CFR Part 11 enabled with self contained, validated reagent packaging.
