Description
Thoma counting chambers (new) are precision haemocytometers made from optical special glass with a double net ruling for reliable cell and particle counting. The chamber depth is 0,1 mm and the bright-line grid supports clear visualisation under the microscope. Each unit is supplied with two cover glasses of 0,4 mm thickness and spring clips for secure seating of the cover glass during use. Designed for applications in accordance with EU Regulation 2017/746 on in vitro diagnostic medical devices (IVDR), these chambers carry the CE mark and a batch number to support full information and traceability. The large pack contains 10 pieces and is suited to routine haematology, cell culture and quality-control workflows where standardised Thoma geometry is required. Manufactured by Marienfeld, the chambers combine durable optical glass with practical handling features for everyday laboratory counting tasks. The bright-line double net division and defined 0,1 mm depth help ensure reproducible volume determination when used with matching cover glasses.

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 Chambres de comptage & hémocytomètres, inside Microscopie et histologie, in Instruments de laboratoire.
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.
