Le xylène est l'intermédiaire standard en histologie car il est miscible avec les alcools tels que l'isopropanol et l'éthanol ainsi qu'avec la paraffine. Dans ce contexte, il est utilisé comme étape intermédiaire entre les séries d'alcools ascendantes et l'inclusion en paraffine. Cela permet de s'assurer que l'alcool est complètement éliminé du tissu. Le xylène peut également être utilisé pour déparaffiner les coupes de paraffine, permettant une coloration ultérieure.

Questions about Xylène (isomères), min. 97 %, pur, pour histologie, 1 l, verre
What is this article?
Xylène (isomères), min. 97 %, pur, pour histologie, 1 l, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Histology reagents & consumables, inside Microscopy & histology, in Instruments de précision.
Histology reagents are the fixatives, the solvents, the paraffins and the stains that turn a tissue into a readable section. The stain and the tissue, not the bottle size alone, choose the reagent. Many of these liquids are flammable or toxic and travel under dangerous-goods rules.
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.
