The USP grade designations ensure that this product complies with the purity standards set by the United States Pharmacopeia and is therefore suitable for food and pharmacy use.
Water, USP Grade is water with a CAS number of 7732-18-5, supplied as a liquid at 100.00% assay. The USP grade means it meets the purity standards set by the United States Pharmacopeia, so it’s suitable for food and pharmacy use. It may also fit applications that are microbiologically sensitive. Paperwork matters with a grade like this, and the Product Manuals tab covers a lot of it: Safety Data Sheet, Technical Data Sheet, GRAS document, Allergen Statement, Country of Origin Document, GMO Free Statement, Pesticide Statement, PFAS/PFOS Free Statement, Residual Solvent Statement, Statement of Source, TSE/BSE Declaration, and the Total Organic Carbon and Conductivity Test Limits document. Certificates of Analysis are listed on the page as well.
You’ll find this water used in hospitals and biochemistry labs, where the water going into a test or a prep can’t be an afterthought. If your results depend on what’s in the water, a vague spec sheet is a real problem. So is a supplier who can’t show you paperwork or offer the size you need. Lab Alley makes that part easy. The documents are on the page, and you can choose a 5 gallon or 55 gallon size. Pick the size you need and add it to your cart. Want regular deliveries? Set up Autoship. Need a different volume?
