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.
