Neubauer Sperm counting chamber

chamber-n-improved-brightline-with-v-06_500_30Superior Counting Chambers are precise measuring instruments to determine the number of particles in liquids.

Our counting chambers with V-slash at the exterior sides of the chamber facilitates the feeding of the capillary gap between chamber bottom and haemocytometer cover glass, this provides easier filling and reducing the risk of overflow. Made of special optical glass in compliance with DIN ISO 12847. Individually tested according to the German Calibration Ordinance planarity and tolerances are strictly observed. Chamber depth 0.1mm Tolerance of depth of chamber max. 2 %. Double counting grids = dual count possibility. To be used with cover glass having a thickness of 0.4 mm. 2 haemocytometer cover glasses 20X26 mm with thickness 0.4 mm are supplied with each counting chamber. Counting grids are engraved into two ground and polished surfaces on the central stage (= chamber bottom). This central stage is located between two elevated also ground and polished stages.

neubauer-gridBright line: The “Bright lined” feature of the chambers have counting grids which are structured into a very thin, transparent metal coating. The bright lines contrast well with the dark metallic background.

Catalogue No PM 0650030 Neubauer Improved, bright line depth 0.1 mm Superior Cover Glasses for counting chambers and haemocytometers. Haemocytometer cover glasses are used to cover specimens in counting chambers. The cover glass is placed on the outer bearing surfaces and due to their flatness adheres very well. Thus it forms an exact capillary gap and defines the volume of the cell suspension over the counting grid. Ground and polished edges, Size  20×26 mm, Thickness 0.4 mm  Made of special optical glass Ready for use, Individually packed in poly bags. 10 pieces in a plastic box, and 10 plastic boxes in a cardboard box.
