Compare prices and buy Sterile Water from 1 research peptide vendor - also called suppliers or sources. Updated daily.
Sterile water with no benzyl alcohol or other preservative, sold by research-peptide vendors as a diluent for lyophilized peptides. With no preservative, nothing inhibits microbial growth once the container is entered, so it suits work that specifies a preservative-free diluent and is meant for single use. Hospira's FDA-approved Sterile Water for Injection is supplied only in single-dose containers. For research purposes only.

Sterile water is not a peptide. PeptideScouter catalogues it because research-peptide vendors sell it alongside the lyophilized vials it is used to dissolve.
Sterile water for injection (SWFI) is purified, pyrogen-free water that meets the US Pharmacopeia standard for injectable use and contains no additives of any kind, whether preservative, buffer or salt. It is packaged in single-dose containers and intended to be used once and discarded. In research-peptide workflows it is one of the diluents used to reconstitute lyophilized (freeze-dried) peptides before further laboratory work.
The key distinction is the preservative. Bacteriostatic water contains an antimicrobial preservative that inhibits microbial growth and lets its vial be entered more than once. Sterile water has no such preservative, so once its container is opened it offers no protection against contamination and is meant for immediate single use. The same difference separates sterile water from the branded Hospira bacteriostatic water product.
Sterile water is the choice when a protocol or product documentation specifies a preservative-free diluent. Tolerance of preservatives is specific to each product. The Pitocin (oxytocin), DDAVP and multiple-dose Vasostrict injection labels list chlorobutanol as a preservative, and an approved hCG product's label recommends bacteriostatic water as its diluent. This is a compatibility consideration, not a preparation instruction.
Because it lacks a bacteriostatic agent, sterile water for injection does not carry the multiple-dose window that applies to bacteriostatic water. Hospira's FDA label for sterile water for injection says not to reuse its single-dose containers and to discard any unused portion, and not to store solutions of drugs reconstituted with it unless the drug's manufacturer directs otherwise.
The vendor listings PeptideScouter indexes title it simply "Sterile Water," a name that does not by itself state whether the product meets the USP standard for sterile water for injection. Because it is priced by volume rather than by milligram of an active compound, PeptideScouter shows sterile water on a per-milliliter basis, the same convention used for bacteriostatic water and other reconstitution products.
Bacteriostatic water contains an antimicrobial preservative, benzyl alcohol in the products indexed here, that lets its vial be entered more than once. Sterile water for injection has no preservative, so it offers no protection against contamination once opened and is intended for single use only.
Sterile water is used when a protocol or product documentation calls for a preservative-free diluent. Tolerance of preservatives is specific to each product. Some FDA-approved peptide drugs are themselves formulated or supplied with a preservative. This is a compatibility consideration, not dosing guidance.
No. Sterile water for injection contains no bacteriostatic preservative, and Hospira's FDA label supplies it only in single-dose containers, with instructions not to reuse them and to discard any unused portion.
Not necessarily. SWFI stands for sterile water for injection, which is preservative-free, pyrogen-free water meeting the US Pharmacopeia standard for injectable use. Sterile water is also sold under other USP names, including Sterile Water for Irrigation, which is labeled not for injection. A product titled simply sterile water does not by itself state which standard it meets.
Sterile Water is sold by 1 research peptide vendor indexed on PeptideScouter, with 2 tracked listings compared per vendor in the table above. Pricing is normalized and refreshed daily.
All 1 indexed research peptide vendor currently have Sterile Water in stock. Stock state is refreshed daily from each vendor's catalog.
Discount codes are issued per vendor rather than per peptide, so any code applies across that vendor's whole catalog. All 1 vendor listing Sterile Water publish a PeptideScouter code, worth 10% off. These listings do not carry a comparable per-milligram price, so code availability is shown without a normalized effective price. Each vendor's code is shown beside its price in the table above.
1 research peptide vendor currently lists Sterile Water on PeptideScouter. We track 2 listings across size and kit variants.
