Description
Water, hypotonic, sterile, free from pyrogen is a specialised laboratory water grade intended for cell culture and related life-science applications. Identified as H₂O with CAS number 7732-18-5 and EG number 231-791-2, it has a molar mass of 18,02 g/mol, a density of 1 g/cm³, and a boiling point of 100 °C. The hypotonic, sterile, and pyrogen-free profile supports workflows in which controlled water quality is required for media preparation, reagent dilution, or general cell-culture handling. Supplied in a 1 l plastic pack from manufacturer Carl ROTH, the product fits routine bench use where single-litre volumes are practical for sterile technique and batch preparation. Laboratories working under cell-culture protocols can use this water when hypotonic conditions and freedom from pyrogens are specified alongside sterility. Clear identity data, including the empirical formula and CAS reference, facilitate documentation in quality systems, while the stated physical properties help users confirm suitability against method or media recipes without relying on unspecified grades of laboratory water.
This article belongs on Disinfectants & biocides, in Cleaning & disinfection.

Questions about Water, hypotonic, sterile, free from pyrogen, 1 l, plastic
What is this article?
Water, hypotonic, sterile, free from pyrogen, 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Disinfectants & biocides, inside Cleaning & disinfection, in Lab safety equipment.
A disinfectant or a biocide makes a kill claim against named organisms, at a stated dilution and contact time, on a stated kind of surface. Without those three, it is a bottle of chemical. The spectrum, bacteria, fungi, spores or viruses, is the specification. It works poorly through dirt.
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 Disinfectants & biocides. The catalogue is Lab safety equipment.
Shelves beside this one are Wipes, tissues & paper towels, Laboratory cleaners & detergents and Cleaning & disinfection (other).
What should I check before I order?
