Description
Formaldehyde solution 35 % is an aqueous fixative grade preparation with a minimum content of 35 %. DAB, intended for histology and related cell-analysis workflows. Identified by CAS number 50-00-0 and empirical formula CH₂O, it has a molar mass of 30,03 g/mol and a density of 1,09 g/cm³. The boiling range is 93 to 96 °C and the flash point is 62 °C, supporting controlled handling in laboratory fixation protocols. Its defined concentration and physical data allow reproducible preparation of fixative baths and working dilutions. The product carries EG number 200-001-8 and UN number 2209. Laboratories use this formaldehyde solution where consistent DAB-grade material is required for histological fixation, specimen stabilisation, and subsequent staining or microscopic examination of cellular structures.

Questions about Formaldehyde solution 35 %, min. 35 % DAB, for histology, 1 l, plastic
What is this article?
Formaldehyde solution 35 %, min. 35 % DAB, for histology, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Histology reagents & consumables, inside Microscopy & histology, in Lab instruments.
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.
