Description
Petroff counting chambers with dark lines and V-groove are precision chambers intended for microscopic enumeration of cells and particles. Each chamber features a double net ruling and a defined depth of 0,01 mm, and is supplied with two cover glasses of 0,4 mm thickness. The dark-line grid improves visual contrast under the microscope, while the V-groove assists controlled sample introduction. Units are delivered without spring clamps and carry both a CE mark and a batch number, supporting full identification and traceability. They are suitable for applications in accordance with EU Regulation 2017/746 on in vitro diagnostic medical devices (IVDR). Offered as a bulk pack of 10 pieces from manufacturer Marienfeld, these chambers are ready for routine counting work in clinical, research and quality-control laboratories. The combination of fixed geometry, dark lines and documented batch coding provides a reliable basis for standardised counting procedures on the laboratory bench.

Questions about Counting chambers Petroff with dark line, CE, with V-slash
What is this article?
Counting chambers Petroff 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 Instruments de précision.
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.
