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.
