Description
tri-Sodium citrate dihydrate is a high-purity citrate salt supplied at min. 99 % under the CELLPURE® grade for demanding life-science and cell-culture work. It carries CAS number 6132-04-3, EG number 200-675-3, the empirical formula C₆H₅Na₃O₇ · 2 H₂O and a molar mass of 294,1 g/mol. Its defined dihydrate stoichiometry supports reproducible weighing and solution make-up in research and production laboratories. This reagent from manufacturer Carl ROTH fits workflows that require consistent salt quality for cell-culture reagents and related biochemical applications. Clear identity data and the CELLPURE® designation help laboratories specify a reliable citrate source when formulating balanced salt solutions or adjusting ionic strength. The solid form allows straightforward storage and dispensing on the bench or in controlled media-preparation areas.

Questions about tri-Sodium citrate dihydrate, min. 99 %, CELLPURE®, 250 g, plastic
What is this article?
tri-Sodium citrate dihydrate, min. 99 %, CELLPURE®, 250 g, plastic 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 Microbiology lab supplies.
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.
