Model: CASY Cell Counter and Analyzer Model TT
The CASY TT is an Electronic Cell Counter and Analyzer System. It is a precision measuring instrument for determining cell counts and cell size distributions, aggregation and viability.
The calibration of the CASY Cell Counter and Analyzer guarantees that the results can be compared from user-to-user, from lab-to-lab, from day to day and from instrument-to-instrument.
The CASY Systems use a label-free, non-invasive method, called the Electrical Current Exclusion method, for measuring cell viability of mammalian cell lines.
The CASY Cell Counter and Analyzer offers a method to analyze even clumpy cell suspensions with its integrated aggregation correction. By analyzing the size distribution, the CASY Cell Counter and Analyzer determines the statistically most occurring cell size, the volume of the statistically ?representative single cell?.
Cell aggregates thereby are classified into their single cells, thus making it possible to determine the single cell count including the number of single cells in aggregates. The CASY Cell Counter and Analyzer represents this correction in the form of an aggregation factor. The mean aggregation factor is used to record the aggregation correction. This parameter also can be used as a further quality control parameter for the characterization of cell cultures.
CASY Model TT comprises the following functional units:
- Measuring stand consisting of measuring unit, pressure systems and main power supply
- Measuring capillaries
- Protection shield
- Control panel with graphic display and 13 control keys.
The control panel consists of a graphic display and a membrane keyboard exhibiting 13 keys. In measuring mode, the graphic display shows the size distribution and indicates the measuring results. All measuring and output parameters can be displayed and adjusted through the menu control.
The keyboard is divided into three functional areas. The top right-hand area accommodates the keys used to enter the measuring and output parameters. The bottom right-hand area accommodates the keys used to control the measuring unit and output the results to the printer. On the left are the keys used to position the evaluation and the normalization cursors. All keys have a clearly defined pressure point.
The CASY System is a development based on extensive experience gained in analytical working methods in the fields of cytobiology, microbiology, biochemistry, and physics. Its ergonomic and easy operation were developed specifically for day-to-day, routine use. Standardized cell counting methods and accurate measurement of cell viability, cell aggregation, and cell volume with high measuring range dynamics make the CASY Cell Counter and Analyzer an indispensable tool for the qualitative and quantitative assessment of cell cultures.
- High-resolution size distribution
- Cell volume:
The cell volume is precisely measured by the CASY Cell Counter and Analyzer. Based on the cell volume, the corresponding cell diameter is calculated
- Aggregation correction:
Determination of the mean degree of cell aggregation. The aggregation factor is used to calculate the total number of single cells, including cells in cell clusters (aggregation correction)
- Viability determination:
Viability of mammalian cell lines and primary cells, when analyzed in monoculture, is measured by a non-invasive method, the electrical current exclusion method
