Description
Howard counting chamber without lines is a precision glass chamber intended for the microscopic examination of fruit juice. The chamber is equipped with two counting lines having a stroke thickness of 1,5–2 μm and spaced 1402 μm apart, providing a defined reference for particle or mould assessment in juice samples. The circular counting area has an approximate inner ring diameter of 18 mm and an outer ring diameter of 22 mm. Chamber depth is 0,1 mm. Supplied without a cover glass, the unit integrates readily into existing microscopy workflows for quality control and analytical laboratories. This counting chamber from manufacturer Marienfeld supports standardised evaluation of fruit-juice preparations where a Howard-type geometry is specified. Compact single-piece format and clearly defined optical path make it a practical tool for routine juice analysis, mould counting and related food-laboratory microscopy tasks that require a shallow, circular observation field with calibrated line spacing.

Questions about Counting chambers Howard without lines,
What is this article?
Counting chambers Howard without lines, 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.
