Description
Agar-Agar, Danish, sugar-containing, powder is a standardised carrageenan mixture supplied for laboratory and technical gelling applications, with CAS number 9002-18-0 and EG number 232-658-1. Presented as a free-flowing powder Carrageenan-based gels are widely used to adjust texture, viscosity and solidification in microbiological media preparation, plant tissue culture supports, food-technology trials and other aqueous gel systems where reproducible setting is required. The standardised mixture helps laboratories maintain batch-to-batch performance when preparing plates, slants or model gels. The kilogram pack size suits higher-throughput media kitchens and shared core facilities that consume gelling agents regularly. Dissolve and process according to established agar or carrageenan protocols for your matrix, and consult the safety documentation for handling guidance on the powdered material.

Questions about Agar-Agar, danish, sugar-contain., powd., Standardised Carrageenan mixture, 1 kg
What is this article?
Agar-Agar, danish, sugar-contain., powd., Standardised Carrageenan mixture, 1 kg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Carbohydrates & sugars, inside Biochemicals & reagents, in Life Science & Microbiology.
A carbohydrate reagent is a sugar or a derivative, specified by identity, anomer where it matters, and purity. Hydrate and anhydrous forms change the mass. A culture-grade sugar and an analytical standard of the same name are different bottles.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
