Coulter Analyzers

The facility houses two coulter analyzers that can be found in room 2-203. They are a Coulter Cytomics FC500 (2-laser, 5-color) and a Coulter Epics XL-MCL (1-laser, 4-colour). Both instruments also measure forward and side scatter.

Please see below for more information about each instrument. Further information about training and technical specifications for these instruments can be obtained from Tharsan Velauthapillai, who can be contacted at
