Cell Counting Chambers ASSISTENT

Description

Counting chambers made of special optical glass. Assistant counting chambers are precision measuring devices.they are used to count the number of particles per unit volume of a liquid. The counting chambers are supplied with CE marking according to IVD Directive 98/79 EC. The lateral marking areas are separated by grooves from the three central, flat-ground ridges. The middle bar is deeper than the two outer bars. This results in the chamber depth. The chamber depth (tolerance ± 2%) depends on the counting net - see descriptions below. The counting nets are engraved in the center bar. Counting chambers with double pitch are standard. The center bar is separated by an additional groove. Light-line counting chambers: The center bar is provided with a chrome layer in which the counting nets are engraved. This results in a better contrast of the lines to the surface. The lines appear bright-lined.
