Description
Thoma counting chambers, CE are precision counting chambers produced from optical special glass for dependable cell and particle enumeration in laboratory and IVD settings. They incorporate a double net ruling with a chamber depth of 0,1 mm and are supplied with two cover glasses of 0,4 mm thickness. The dark-line grid offers distinct contrast for reading the ruled areas under the microscope. Configured without spring clips, the chambers are suitable for applications according to EU Regulation 2017/746 on in-vitro diagnostic medical devices (IVDR). CE marking together with a batch number ensures comprehensive information and full traceability. Available from manufacturer Marienfeld in a bulk pack of 10 pieces, these Thoma chambers serve routine haematology, cell counting and quality-controlled diagnostic workflows that require a shallow, well-defined chamber volume. The optical special-glass body supports clear visualisation of the dark-line net across repeated preparations and multiple users.

Questions about Counting chambers Thoma, CE,
What is this article?
Counting chambers Thoma, CE, is the article on this page. Luminix Health distributes Marienfeld 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.
