Description
Polypropylene glycol 400 is a biochemistry-grade polyether with molar mass 400 g/mol, density 1,01 g/cm³, and empirical formula [C₃H₆O]ₙ (CAS 25322-69-4). The material shows a flash point of 195 °C and a boiling range of 288 to 310 °C, supporting controlled handling in laboratory preparation and formulation work. Physical data from manufacturer Carl ROTH enable straightforward integration into protocols that specify PPG 400. The clear liquid profile and stated molar mass help laboratories match viscosity and solubility needs in molecular and biochemical workflows. Use this grade where consistent polypropylene glycol 400 quality is essential for reproducible experimental conditions.

Questions about Polypropylene glycol 400, for biochemistry, 250 ml, glass
What is this article?
Polypropylene glycol 400, for biochemistry, 250 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biochemicals (other), inside Biochemicals & reagents, in Microbiology lab supplies.
These are the biochemical reagents that are not an amino acid, a sugar, a lipid, an enzyme or an antibiotic. Identity and purity still decide the bottle. If the compound is light-sensitive or hygroscopic, the handling on the label is part of the specification.
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.
Which category should I open next?
The category is Biochemicals & reagents. The sub-category is Biochemicals (other). The catalogue is Microbiology lab supplies.
Shelves beside this one are Amino acids & peptides, Carbohydrates & sugars, Coenzymes, nucleotides & vitamins, Enzymes & substrates, Antibiotics & antimycotics, Lipids, steroids & fatty acids and Detergents & surfactants.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
