Description
ROTI®Histofix 4,5% is a ready-to-use formaldehyde fixative supplied in prefilled containers for histological fixation and cell biology applications. The solution is acid-free at pH 7 and phosphate-buffered, providing a balanced medium for preserving tissue and cellular morphology before further processing or analysis. Physical characteristics include a density of approximately 1 g/cm³, a flash point between 79 and 85 °C and a boiling point of 97 °C. This pack contains 100 prefilled units in cardboard packaging, removing the need to prepare and buffer formaldehyde solutions on site and supporting more consistent fixation practice. It is suited to laboratories performing routine fixation in cell analysis, histology and related life-science workflows. The product comes from manufacturer Carl ROTH within the ROTI®Histofix range and is intended for immediate use. Prefilled containers simplify immersion at the bench or point of collection and help standardise fixation conditions across specimen series. Research groups and histology units that rely on phosphate-buffered formaldehyde at 4,5 % will find this format practical for organised sample handling, reduced preparation time and reliable day-to-day fixation performance.

What is this article?
ROTI®Histofix 4,5%, prefilled containers, formaldehyde,, 32 unit(s), cardboard 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.
