CASY® TT

Cell Counter + Analyzer

The CASY® Cell Counter + Analyzer System Model TT determines not only the cell number but also the size ­distribution and viability of a cell sample quickly and reliably. In addition, the aggregation level in the cell sample is determined and automatically included in the determination of the cell concen­tration. The basic results provided are:

  • Cell concentration
  • Cell viability
  • Cell volume
  • Cell aggregation
  • Cell debris


Electrical Current Exclusion (ECE®) is the only ­well-accepted method for the dye-free determination of cell viability. Together with the short measurement time and the low sample volume, CASY®-Technology offers a unique combination of features for quality­control of cell cultures that makes it fast, easy to use, flexible and precise.

CASY® Model TT is based on the internationally accepted reference method for cell counting, ISO 13319. In addition, the system is equipped with an advanced method for digital pulse processing called “Pulse Area Analysis”. This technique is used to get complete information from the signals created when a cell or particle passes through the high precision measuring pore in a low voltage field. Each single object is scanned with a frequency of one million measurements per second, resulting in up to hundreds of readings per cell. Thus, the complete time course of the signals is taken into account when analyzing samples. Pulse Area Analysis provides an outstanding dynamic measurement range. It is the basis for the dye-free, non-invasive determination of cell viability.
