Description
ROTI®Histofix 4.5 % acid free (pH 7) is a phosphate-buffered, ready-to-use formaldehyde solution for fixation in cell biology and histological workflows. Formulated acid-free at pH 7, it supports reliable sample preservation ahead of cell analysis and related life-science procedures. The solution has a density of approximately 1 g/cm³, a flash point in the range 79 to 85 °C and a boiling point of 97 °C, giving clear physical reference points for routine laboratory handling. Categories of use include fixation within cell biology and cell analysis settings where a neutral, phosphate-buffered formaldehyde medium is preferred. The product is offered from manufacturer Carl ROTH as part of the ROTI®Histofix range and is intended for professional laboratory application. Its combination of defined pH, acid-free character and convenient bulk volume makes it a straightforward choice for standardised fixation protocols that demand reproducible, ready-to-deploy formaldehyde solution.

Questions about ROTI®Histofix 4.5 % acid free (pH 7), phosphate-buffered, ready-to-use, 500 ml
What is this article?
ROTI®Histofix 4.5 % 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.
