Description
Sedgewick Rafter counting chamber without counting grid is a glass chamber supplied with cover glass for quantitative microscopy work where a ruled grid is not required. It is particularly suited to APHA methods and to the analysis of larger plankton species. The open chamber design supports both upright and inverted microscopes, giving flexibility across common laboratory microscope configurations. When paired with an ocular micrometer such as a Whipple eyepiece micrometer, the chamber enables reliable counting and sizing workflows without an etched grid on the chamber floor. Manufactured by Marienfeld, this glass counting chamber is intended for routine plankton and water-analysis applications that benefit from a clear, ungridded viewing field and straightforward sample loading under the cover glass. The single-piece unit integrates easily into existing microscopy setups for environmental, limnological and related laboratory protocols that specify Sedgewick Rafter geometry without a counting net.
This article is part of Counting chambers & haemocytometers, in Microscopy & histology.

Questions about Counting chambers Sedgewick Rafter, without grid
What is this article?
Counting chambers Sedgewick Rafter, without grid 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.
