The Neubauer Counting Chamber, manufactured by Marienfeld, is a high-precision measuring instrument designed specifically for counting particles in liquid samples. Compliant with DIN 12847 standards, this counting chamber is crafted from premium optical glass, ensuring exceptional planarity and adherence to strict tolerances enforced by the German Calibration Ordinance. Its maximum depth tolerance of just 2% guarantees accurate and reliable results, making it an essential tool for laboratories involved in cell counting and other in-vitro diagnostic (IVD) applications. The chamber features two sets of grids allowing for duplicate counting, thus ensuring accuracy and reliability of measurements. A cover glass of 0.4 mm thickness is included, which is crucial as thinner glasses may bend under capillary forces. This product comes with 10 individually packed pieces in a transparent plastic box which provides safe storage and easy accessibility. Compatibility with various sizes of cover glasses (including haemacytometer cover glasses 20 x 26 mm and sizes for Fuchs-Rosenthal and Nageotte chambers) adds to its versatility. Whether used in research or quality control laboratories, the Neubauer Counting Chamber stands out for its reliability, precision, and convenience, making it an invaluable addition for labs focusing on cell suspensions.

Marienfeld Superior counting chambers are precise measuring instruments to determine the number of particles in liquids.
made of special optical glass
in compliance with DIN 12847
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 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 pieces in a carton
counting grids are structured 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.
Dark line:
Under the microscope the lines of the standard counting chambers appear dark.
Bright line:
Counting chambers with bright lines 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.
