Counting chamber Thoma with double ruling is a precision haemocytometer manufactured to DIN 12847 for accurate cell enumeration. The chamber incorporates a double network ruling and is delivered in a transparent plastic box complete with two Haema-Cytometer cover glasses of 0,4 mm thickness plus two spring clamps. CE marking is included for laboratory compliance. Offered by manufacturer Witeg, this version provides secure cover-glass fixation via the integrated spring clamps, ensuring stable sample preparation during counting. Net weight is 0,044 kg per single piece. The double ruling supports clear visualisation of counting grids under the microscope, making the chamber suitable for haematology, cell culture and related analytical tasks. The transparent box protects all components, while the spring clamps maintain consistent cover-glass positioning. This Thoma counting chamber is ready for immediate use in standardised cell-counting protocols that require reliable grid geometry and secure assembly. The complete set facilitates reproducible results in routine laboratory workflows.

Questions about Counting chambers Thoma
What is this article?
Counting chambers Thoma is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Counting chambers & haemocytometers, inside Microscopy & histology, in Instrumenten.
A counting chamber is a slide with a ruled grid of known depth, so cells in a volume can be counted under a microscope. A haemocytometer is that chamber for blood or for cultured cells. The depth and the ruling are the specification. A scratched grid miscounts.
A light microscope forms an image with glass lenses and transmitted or reflected light. A stereo microscope is the lower-magnification instrument for dissecting and for looking at a surface. Fluorescence needs a light source and filters matched to the dye. Histology is the preparation that makes a tissue readable: fixation, a cassette, a section, a stain. The objective's magnification and numerical aperture decide the resolution. The slide and the cover glass decide whether the section sits in the focal plane. Stains and dyes as substances are identified on PubChem. Papers on the methods are on PubMed.
