Description
Helber counting chambers 0,02 mm, dark-lined, are precision haemocytometers built to the Thoma system with a special chamber depth. Each unit is made from optical special glass and carries a double net ruling for clear, dark-lined grid visibility under the microscope. The chamber depth is 0,02 mm; two cover glasses of 0,4 mm thickness are included, and the design is supplied without spring clamps. These chambers are intended for applications under EU Regulation 2017/746 on in vitro diagnostic medical devices (IVDR), and they bear the CE mark together with a batch number to support full information and traceability. Offered from manufacturer Marienfeld in a bulk pack of 10 pieces, they suit specialised cell and particle counting where a reduced depth and standardised Thoma geometry are required. The optical-glass construction and double net division support accurate enumeration in routine and advanced laboratory workflows that need documented batch control and regulatory alignment.
This article is part of Counting chambers & haemocytometers, in Microscopy & histology.

Questions about Counting chambers Helber 0.02 mm, dark line, CE
What is this article?
Counting chambers Helber 0.02 mm, dark line, 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.
