Description
Polypropylene glycol 4000 is a polymeric diol offered for biochemistry applications, with the repeating unit formula [C₃H₆O]ₙ and a stated molar mass of 4000 g/mol (CAS number 25322-69-4). The material shows a density of 1,004 g/cm³, a flash point above 100 °C, and a boiling range of 288 to 310 °C, giving a clear physical profile for handling and process planning. This grade is Physical data from manufacturer Carl ROTH support selection alongside other polypropylene glycols (PPG) used as polymer building blocks or performance materials. The viscous liquid character associated with this molar-mass grade makes it relevant when a higher-molecular-weight PPG is preferred over lower oligomers. Use under standard laboratory chemical-hygiene practice, taking account of the elevated boiling range and flash-point information.

Questions about Polypropylene glycol 4000, for biochemistry, 250 ml, glass
What is this article?
Polypropylene glycol 4000, 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.
