UsingaCountingChamber
Using a Counting ChamberFor microbiology, cell culture, and many applications that require use of suspensions of cells it is necessary to determine cell concentration. One can often determine cell density of a suspension spectrophotometrically, however that form of determination does not allow an assessment of cell viability, nor can one distinguish cell types.A device used for cell counting is called a counting cham......阅读全文
