Description
Helber counting chambers with dark lines, CE marked and equipped with a V-groove, are precision glass slides for microscopic cell and particle enumeration. Each chamber features a double net ruling with a depth of 0,02 mm and is supplied with two cover glasses of 0,4 mm thickness. The dark-line grid improves contrast under the microscope, while the design omits spring clips for straightforward loading. These chambers support applications in accordance with EU Regulation 2017/746 for in-vitro diagnostic medical devices (IVDR) and carry the CE mark together with a batch number for full identification and traceability. Offered in a bulk pack of 10 pieces from manufacturer Marienfeld, they are intended for routine counting work in clinical, research and quality-control laboratories. The V-groove aids sample introduction, and the shallow 0,02 mm chamber depth is suited to the Helber counting format. Consistent ruling and cover-glass thickness help maintain reproducible counting conditions across the pack.
This article is part of Counting chambers & haemocytometers, in Microscopy & histology.

Questions about Counting chambers Helber with dark line, CE, with V-slash
What is this article?
Counting chambers Helber with dark line, CE, with V-slash 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.
