Camera haemacytometer Neubauer Improved Brightline,depth 0.1mm 0.0025mm2

Neubauer Counting Chamber is a device used for cell counting. Counting Chambers are the finest quality, optically ground, and polished milled glass chambers. The Neubauer Counting Chamber is diamond etched and has a double improved Neubauer Ruling, meeting the most demanding of standards.Rulings cover 9 square millimeters. Boundary lines of counting chamber ruling are the center lines of the groups of three. The central square millimeter is ruled into 25 groups of 16 small squares, each group separated by triple lines, the middle one of which is the boundary. The ruled surface is 0.10mm below the cover glass, so that the volume over each of the 16 small squares is .00025 cubic mm.

Features:

Cell Depth: 0.100mm+/-2% (1/10mm)
Volume: 0.1 Microliter
Ruling Pattern: Improved Neubauer, 1/400 Square mm

Counting chambers are precise measuring instruments to determine the number of particles in liquids.

made of special optical glass
in compliance with DIN 12 847
individually tested according to the German Calibration Ordinance
planarity and tolerances are strictly observed
tolerance of depth of chamber max. 2 %
our counting chambers for investigations of cell suspensions are equipped with 2 sets of grids. In-vitro diagnostic (IVD) applications generally require duplicate determinations. Double counting grids = double check possibility.
a cover glass with a thickness of 0.4 mm is placed on top of both external stages of the counting chamber to limit the volume over the counting grids. Thinner coverslips cannot be used as they bend because of the capillary forces.
with 2 haemacytometer cover glasses 20 x 26 x 0.4 mm which are suitable for most counting chambers. For spare cover glasses please see here.
counting chambers Fuchs-Rosenthal require cover glasses 24 x 24 mm and counting chambers Nageotte require cover glasses 30 x 30 mm.
individually packed in transparent plastic box, 10 pcs. in a carton
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.
Bright line:
Bright lined counting chambers have counting grids which are structured into a very thin, transparent metal coating. The bright lines contrast well with the dark metallic background and this facilitates evaluating cell suspensions.
