Counting chambers Marienfeld, Dark Line, with clamps

Reference
MF-TELK-DL-MKLEM

The counting chambers serve to determine the number of particles per volume unit of a liquid. The particles (e.g. leucocytes, erythrocytes, thrombocytes, bacteria, fungus spores, pollen) are visually counted under a microscope. The types of counting chambers differ in counting grids and the depths of the chambers. Orthogonal lines form grids which become visible by magnifying them with a microscope. The grid of a counting chamber is engraved into the surface of its base.

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 ISO 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.   
  • counting chambers Fuchs-Rosenthal require cover glasses 24 x 24 mm and counting chambers Nageotte require cover glasses 22 x 30 mm or 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.
  • Dark line:
    Under the microscope the lines of the standard counting grid appear dark.
  • 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.
