CASY TT

Cell Counter + Analyzer for research labs with high sample throughput and/or GLP certification demanding highest degree of reproducibility


Areas of Application

  • Reliable multi-parameter QA on cell cultures at lowest cost
  • Simultaneous determination of cell count, size distribution, cell volume, aggregation and cell debris in less than 10 seconds, no dyes used
  • Need for highest accuracy and reproducibility, which dye-based methods and systems with autosampler = longer waiting times cannot achieve

 

Three different capillary sizes enable a measuring range reaching from 0.7 µm up to 120 µm:

Capillary Ø [µm]Size range [µm]Application areas
45 0,7 - 30

Debris, Bacteria, Spores

60 1,2 - 40

Yeast, Algae, Erythrocytes, Pollen, Plankton, Parasites, Sperms

150 3,2 - 120

Cell lines, Primary mammalian cells, white blood cells, stem cells, fish cells, large algae and protozoa, plant cells and protoplasts


For the CASY® TT a large and continuously growing library of reference data is available. The required software CASY®excell comes with every system. Please see the following link for some key examples: cellcounting.de/cell-library

CASY: Budget-friendly Benefits to Your Cell Analysis

  • Dye-free, non-invasive determination of the cell activity via ECE® (electric current exclusion method): produces correct data on viability and vitality even for very sensitive cells and partly damaged cells
  • Aggregation factor calculation based on particle volume: Correct cell count even if large cell clusters are present
  • No single use consumables like counting slides or counting capillaries: very low cost per single count experiment

Designed for the Demanding Quality Control

The CASY TT was developed primarily for use in cell culture research in universities and in pharmaceutical and biotech research companies and comes as a stand-alone unit. As such the space requirements are very small and it fits into even the smallest lab. It offers the following key features:

  • Very easy to operate, separate control panel with graphical display and plastic foil keypad
  • Display of size distribution histogram and key results on the same screen mask
  • Stores up to 20 parameter sets for different cell types
  • Dimensions (HxWxD): 39 cm x 31 cm x 39 cm, excl. keypad
  • Results can be stored externally by using the CASYworX software; requires MS Excel

CASY - Technical Overview

Measuring TechniqueCASY TTCASY TTC
measuring principle capillary particle counter with pulse area analysis
Parameters determined Cell size distribution, cell count, cell concentration, cell viability, cell aggregation, cell debris, cell volume (peak), average cell diameter
Determination of size dsitribution Digital pulse count/area analysis, 1 Million data points per second, equals several 100 data points per cell
 
Viability measurement

Electrical Current Exclusion (ECE®)
Dye-free, non-invasive determination of the membrane permeability

Aggregation factor determination Based on the volume of the single free cell, resolves clusters from 2 up to several hundred cells
Concentration determination Counting volume controlled opto-electronically, maintenance free, calibrated for life time
