Description
Water, purified, Ph.Eur., USP is high-purity laboratory water with empirical formula H₂O, CAS number 7732-18-5 and EG nr. 231-791-2. The molar mass is 18,02 g/mol, density is 1 g/cm³ and the boiling point is 100 °C, matching the expected physical profile of purified water for pharmaceutical and laboratory use. Compliance references to Ph.Eur. and USP support applications that require pharmacopoeia-grade purified water as a raw material or process medium. This purified water from manufacturer Carl ROTH is positioned for use among raw materials for disinfectants and broader laboratory aqueous preparations where defined purity is essential. Clear identity data, including CAS and EG numbers, facilitate documentation in quality systems and method records. The single-litre plastic presentation suits routine dispensing without bulk handling. Laboratories can apply the water wherever purified aqueous media meeting Ph.Eur. and USP expectations are specified.

Questions about Water, purified, Ph.Eur., USP, 1 l, plastic
What is this article?
Water, purified, Ph.Eur., USP, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Cleaning & disinfection (other), inside Cleaning & disinfection, in Lab safety equipment.
This shelf holds cleaning and disinfection articles that are not a plain detergent, a wipe or a named disinfectant: combined products and odd formats. Read the claim. A product that only cleans should not be described as a disinfectant.
Cleaning removes soil. Disinfection kills or inactivates microbes that remain. They are not the same step, and a disinfectant on top of dirt does less than the label claims. The spectrum, the contact time and the surface decide the product. A wipe is the mechanical half of the same job. Chemical classification is on ECHA. Workplace practice is EU-OSHA on dangerous substances. Biosafety context is the WHO biosafety topic.
Which category should I open next?
The category is Cleaning & disinfection. The sub-category is Cleaning & disinfection (other). The catalogue is Lab safety equipment.
