"Perchloric Acid"

Accessories for Pharmaceutical Underbench Perfection Refrigerators Compliant with DIN 13277

Supplier: Liebherr

The didymium liquid filter consists of praseodymium and neodymium, dissolved in perchloric acid. This filter is ideally suited for checking the wavelength accuracy of spectrophotometers in the UV and visible range. It has a spectrum with a variety of characteristic, very well-defined peaks in the range between 320 and 870 nm.

Cetrimonium bromide ≥98% for molecular biology

Supplier: MP Biomedicals

Cetyltrimethylammonium bromide is a phase transfer catalyst ideal for the precipitation of DNA. Hexadecyltrimethylammonium bromide is a bactericidal, cationic detergent. Its activity is neutralized by soaps and anionic detergents (i.e., SDS). Trimethylammonium bromide compounds form insoluble complexes with SDS. It is active at alkaline pH against both Gram positive and Gram negative organisms.

Cetyltrimethylammonium bromide ia used as an cationic surfactant suitable for the isolation of high molecular weight DNA in plants and other organisms(by a rapid method) as well as plant DNA for use in PCR analysis. It has been used to precipitate nucleic acids. CTAB provides enhancement of Concanavalin A mediated agglutination. It has been used for the determination of protein molecular weights in electrophoretic systems and for determination of critical micelle concentration of detergents. CTAB has also been used as a titrant for potentiometric titration of perchlorate and as a phase-transfer catalyst in reduction of arenes and heterocyclic compounds.
