Cell Counter + Analyzer for the high end research lab with extended demand for reproducibility, sample throughput, documentation of results and for research areas that work under GLP/GMP regulations.

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, avoiding any dyes
  • Need for highest accuracy and reproducibility, which dye-based methods and systems with autosampler (= longer waiting times) cannot achieve
  • Laboratories with several users and different applications 
  • Need for highest quality documentation and evaluation of results
  • Controlled work environment and SOPs that require compliance with GLP/GMP

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 CASY TTC a large and continuously growing library of reference data is available. The required software CASY®datadoc comes with every system. Please see the following link for some key examples: Brochures & Applications.

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 count

Designed for the Demanding Quality Control

CASY TTC was developed especially to meet the requirements in QA of cell culture in research labs as well as in process development and production control. It fulfills the high standards of documentation quality and comprehensive data evaluation needs and was designed to meet the special requirements of labs with a very high number of users and many different applications.

  • A very comfortable windows-based user interface, menus driven and equipped with a full size computer monitor for displaying results and the high res size distribution histograms (1024 size channels)
  • Unlimited storage of cell line/application -specific set-ups
  • LAN interface to connect the systems to data storage and network printers
  • Full flexibility for data evaluation: either directly on the embedded PC or externally using CASY®datadoc software
  • Full GLP/GMP/21 CFR 11 compliance, 3 user levels (guest, user, admin), checksum-secured file formats, electronic signatures and audit trails
  • Simple validation of Analyzer system and embedded PC (IQ/OQ)
  • Dimensions (HxWxD): 65 cm x 41 cm x 39 cm – w/o keyboard and mouse

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
