Cell Counting

Our ConSta 1.0 Beads are a certified suspension of mono dispersal polystyrene beads to verify the concentration accuracy of your cell counting system based on image recognition. They are applicable to various cell analyzers like Cedex, Cedex HiRes, BioProfile FLEX and Vi-CELL. The beads can be used according to the standard operating procedures of the instrument supplier. Each single bottle of ConSta 1.0 is certified by triplicate analysis and fulfills highest requirements in terms of quality. The actual concentration of each bottle is confirmed by a Certificate of Analysis. This product is designed and produced to follow the guidelines of GMP and is traceable to official norm standards (Federal Institute of Physics and Technology, Berlin). We optimized the liquid volume and composition to adapt it to practice and to reduce foam formation.
