Instructions for use

The Neubauer counting chamber is used to count cells in a biological fluid by observing through a microscope a calibrated grid of which the exact dimensions (including depth and volume) are known. A simple calculation allows the number of cells per ml or another volume unit to be determined.

Please consult the “Updated laboratory procedures, 2022” available online via the Laboratory working Group sharepoint page: Laboratory Procedures and Resources.
