Description
Cesium sulphate is a high-purity inorganic salt offered at minimum 99,99 % p.a. grade, with empirical formula Cs₂SO₄, CAS number 10294-54-9 and EG number 233-662-6. The reagent has a molar mass of 361,89 g/mol and a density of 4,25 g/cm³, providing a well-characterised cesium source for demanding analytical and molecular-biology work. Cesium sulphate from manufacturer Carl ROTH is specified p.a. at min. 99,99 %, supporting applications in DNA/RNA isolation workflows, ultracentrifugation media and other life-science protocols that rely on high-assay Cs₂SO₄. The solid is also used in inorganic synthesis and materials studies where low impurity levels matter. specification.

Questions about Cesium sulphate, min. 99.99 %, p.a., 100 g, plastic
What is this article?
Cesium sulphate, min. 99.99 %, p.a., 100 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Molecular biology reagents (other), inside Molecular biology, in Microbiology lab supplies.
These are the molecular-biology reagents that are not an extraction kit and not a PCR master mix: buffers, dyes, ladders' companions, modifying enzymes. Nuclease-free is a claimed property and the reason the bottle costs what it does. A laboratory-grade chemical of the same formula is not a substitute.
Molecular biology here is the handling of DNA and RNA. Extraction kits break the cell and then separate the nucleic acid from protein and from the other nucleic acid. PCR and qPCR reagents copy a chosen sequence so it can be seen. The enzymes and the nucleotides are what the copy depends on. Nuclease contamination destroys the sample before the kit can save it. Sequences are on NCBI Nucleotide. Papers are on PubMed.
Which category should I open next?
