Description
Thoma counting chambers (new) are precision haemocytometers manufactured from special optical glass for dependable cell and particle enumeration in laboratory and clinical settings. A double net division and a chamber depth of 0,1 mm provide the geometric basis for accurate concentration measurements under the microscope. Two cover glasses of 0,4 mm thickness are included to create a defined sample volume across the ruled field. The dark-line grid offers high visual contrast, making the counting squares straightforward to locate. Integrated spring clips hold the cover glass securely in place during filling and observation. CE-marked and carrying a batch number for complete information and traceability, the chambers support applications according to EU Regulation 2017/746 for in-vitro diagnostic medical devices (IVDR). Offered by manufacturer Marienfeld in a bulk pack of 10 pieces, they are well suited to busy haematology laboratories, research groups and quality-control environments requiring reproducible volumetric counting.
This article is part of Counting chambers & haemocytometers, in Microscopy & histology.

Questions about Counting chambers Thoma neu, CE,
What is this article?
Counting chambers Thoma neu, 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.
