What bacteriostatic water is
Bacteriostatic water is sterile water to which benzyl alcohol has been added at 0.9%. The benzyl alcohol inhibits the growth of bacteria in the vial after the stopper has been punctured, which is why a multi-dose vial can be drawn from more than once, whereas plain sterile water for injection is single use. It is the diluent most commonly cited in the peptide research literature for reconstituting lyophilised (freeze-dried) peptide powder before laboratory use.
Handling and storage
Store the sealed vial at room temperature and protect it from light. Swab the stopper before each puncture and use a fresh sterile needle every time. Once the stopper has been punctured, discard the vial after 28 days regardless of how much remains. Do not use if the solution is cloudy or contains particles. Keep the batch number for certificate lookup.
Which vial size do I need?
A 10 ml vial reconstitutes several 5 mg or 10 mg peptide vials at the concentrations typically described in the literature, so one vial of bacteriostatic water is usually enough to pair with a small research order. It is listed as an accessory alongside every lyophilised Origin Peptides vial.
Frequently asked questions
Is bacteriostatic water the same as sterile water? No. Sterile water for injection contains no preservative and is single use once opened. Bacteriostatic water contains 0.9% benzyl alcohol, which allows repeated withdrawals from the same vial for up to 28 days.
How is it shipped? Orders placed before the daily cut off are despatched the same working day by tracked delivery, usually arriving within two to three working days for UK addresses, with a next day upgrade available at checkout. Parcels are plain and unbranded. Vials are packed to protect the glass in transit.
Is a certificate of analysis available? Yes. Every batch is third-party tested and the certificate can be matched to the batch number printed on the vial. Quote the batch number to live chat or the contact form if you need the report for your research records.
