Chamber for microscopic counting of cellular elements in liq.

摘要

The chamber for microscopic counting of cellular elements in liq. has a glass support plate with a counting grid, with pins at the edge of the grid. The pins hold a cover slip at a given distance from the surface of the support plate. The grid is made up of squares, which define volume elements between the support plate and cover slip of linear ratio 1:1:0.8 to 1:1:1.2. The length representing the height of the counting chamber is more than 0.4mm; and the chamber volume is more than 40 microl.
