Description
Counting chamber Thoma with double ruling is a precision haemocytometer designed for cell counting applications in accordance with DIN 12847. The chamber features a double network ruling that enables accurate enumeration of cells under the microscope. It is supplied in a transparent plastic box together with two Haema-Cytometer cover glasses of 0,4 mm thickness. The CE marking confirms conformity for laboratory use. This Thoma-type counting chamber from manufacturer Witeg is intended for routine haematological and cell culture work where reliable grid-based counting is required. The double ruling provides clear reference lines for improved counting precision. Net weight is 0,038 kg per unit, offered as a single piece. The transparent storage box protects the chamber and cover glasses during storage and transport. Suitable for laboratories performing standardised cell counts, the chamber supports reproducible results when used with the matching 0,4 mm cover glasses. The compact design fits standard microscope stages for everyday analytical 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 Lab instruments.
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.
