Countstar BioTech Automated Cell Counter

Countstar® BioTech

Automated Cell Counter
Accurate cell analysis for:
  • Trypan blue Cell Counting
  • Aggregated Cell Analysis
  • Cell Diameter Analysis
  • Cultivation time chart (CTC)
Product Overview
The Countstar® is designed based on the classic Trypan Blue staining principle, integrating the advanced “fix focus” optical imaging work bench and the most advanced cell recognition technologies and software algorithms. Countstar BioTech not only provides the cell concentration and viability, but also provides the average diameter and average circularity, and showing the diameter range and aggregation of cells in histograms etc.

1. Trypan blue cell counting and viability

Countstar is applicable to cells with diameter between 5-180um, like mammalian cell, insect cell, and some planktons.

2. Aggregated Cell Analysis

Some primary cells or subculture cells are prone to aggregate when poor culture state or excessive digestion, thus causing great difficulty in the counting of cells. With the Aggregation Calibration Function, Countstar® can realize a stimulation calculation of aggregations to ensure accurate cell counting and obtain the aggregation rate and the aggregation histogram, thus providing basis for experimenters to judge the state of cells.
Countstar can count the aggregated cells one by one.


3. Cell Size Analysis

The change of cell size is a key feature and is commonly measured in cell research. Normally it will be measured in these experiments: cell transfection, drug test and cell activation assays. 

4. Overlay Analysis of the Cell Growth Curve

In cell culture, the study of pharmacology and toxicology often requires the overlay analysis of multiple growth curves in order to find the optimal culture conditions or the best dosage. Countstar® can directly call up multiple growth curves for comparative analysis.
