Description
Rose Bengale B solution is a 1 % aqueous dye preparation for biological staining and related laboratory applications, identified by CAS number 632-69-9 and empirical formula C₂₀H₂Cl₄I₄Na₂O₅. The solution has a molar mass of 1017,65 g/mol, a density of 1 g/cm³ and a boiling point of 100 °C, with EG nr. 211-183-3. This ready-to-use format from manufacturer Carl ROTH reduces preparation steps at the bench while keeping the dye available in a compact pack. Categories cover dyes and pigments for biological applications, so the product fits staining protocols that call for Rose Bengale B in water. The dropper bottle supports precise addition to slides, media or small reaction volumes. Laboratories can incorporate the solution into routine biological staining sequences where a defined 1 % aqueous concentration and clear identity data are required for reproducible results.

Questions about Rose Bengale B solution, 1 % in water, 10 ml, dropp. bottle
What is this article?
Rose Bengale B solution, 1 % in water, 10 ml, dropp. bottle is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dehydrated culture media (agar & broth bases), inside Culture media & microbiology, in Life Science & Microbiology.
A dehydrated medium is a powder the laboratory dissolves, sterilises and pours. The formulation name, the supplements it still needs, and the grams per litre are the specification. Two powders with similar names, one selective and one not, grow different organisms.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
