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 is part of Cell culture media & sera, in Cell culture.

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 Cell culture media & sera, inside Cell culture, in Microbiology lab supplies.
Cell-culture medium is the liquid a cell line grows in. Serum, often fetal bovine, supplies what the basal medium does not. With or without glutamine, with or without phenol red, and the serum origin are different products. Serum is a cold-chain article and is never part of free standard delivery.
Cell culture grows cells outside the body. The medium, often with serum, supplies what the flask does not. A flask or a dish is the vessel, treated so the cells attach or left untreated so they float. Contamination by microbes, or by another cell line, is the ordinary failure. Cold-chain articles in this work, including serum, are never part of free standard delivery. Lines are catalogued by ATCC. Papers are on PubMed. Practice is summarised by the WHO laboratory biosafety topic.
