Description
ROTI®Histofix 4 %, acid free (pH 7) is a phosphate-buffered, ready-to-use formaldehyde solution for fixation in cell biology and histological sample preparation. The acid-free formulation is buffered to pH 7, supporting gentle, controlled fixation of cells and tissues ahead of downstream cell analysis. Physical data include a density of approximately ~1 g/cm³, a flash point of 79 to 85 °C, and a boiling point of 97 °C, consistent with aqueous formaldehyde fixatives used in life-science laboratories. This ready-to-use histofixative from manufacturer Carl ROTH avoids on-site dilution steps and fits standard laboratory fixation routines in cell biology. size suits shared core facilities and busy histology benches that require a stable, phosphate-buffered 4 % formaldehyde fixative at neutral pH for reproducible sample preservation prior to staining or further analytical work.

Questions about ROTI®Histofix 4 %, acid free (pH 7), phosphate-buffered, ready-to-use, 500 ml
What is this article?
ROTI®Histofix 4 %, acid free (pH 7), phosphate-buffered, ready-to-use, 500 ml 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.
