The Via2-Cassette™ is our unique cell sampling device, eliminating human error by combining cell sampling, staining and loading into a single press on a piston. Individually volume-calibrated, it guarantees the highest precision in cell counting. The Via2-Cassette™ is a disposable plastic unit containing the fluorescent dyes used for analysis to ensure user safety and operational ease.
The pre-loaded and immobilized acridine orange (AO) and DAPI dyes label total cell and dead cell populations, respectively. No human bias will influence cell definition and analysis results. For further precision and reproducibility of results, the cassette's measurement chamber is individually volume-calibrated at time of production, and this is detected for each sample at time of analysis for a precise cell concentration. No user or pipetting errors interfere with data generation. You can load a cell sample into the cassettes by simply submerging the built-in pipette into the cell suspension and pressing the piston before running your analysis.
