Product overview
Bacteriostatic Water 30ml is a sterile multi-dose diluent used in the laboratory to reconstitute lyophilized research peptides. Each 30ml vial is filled with water for injection containing 0.9% benzyl alcohol as a preservative, allowing repeated punctures over the working window without microbial growth.
This SKU is a utility item for the research bench. It is not a peptide and carries no pharmacological activity of its own.
Reconstitution and storage
This product is itself the diluent. Use sterile technique when withdrawing volume — wipe the stopper with isopropyl alcohol and use a fresh needle for each draw.
Store unopened at room temperature in the original sealed vial. Once the stopper has been punctured, store at 2-8 °C and discard any remaining volume 28 days after first puncture, regardless of remaining quantity. The benzyl-alcohol bacteriostat is validated for that window only.
Kit contents
- 1 × 30ml multi-dose vial of sterile 0.9% benzyl-alcohol bacteriostatic water
- 1 × certificate of analysis (lot-specific)
- 1 × handling insert
Typical research use
In published peptide-handling protocols, lyophilized vials are reconstituted with 1-3 mL of bacteriostatic water per vial to achieve common working concentrations. A single 30ml vial therefore supports reconstitution across many peptide vials within the 28-day post-puncture window.
Frequently asked questions
Is this product for human consumption?
No. This product is sold strictly for laboratory research use only. It is not a drug, food, cosmetic, or dietary supplement and is not intended to diagnose, treat, cure, or prevent any disease.
How is bacteriostatic water different from sterile water?
Bacteriostatic water contains 0.9% benzyl alcohol as a bacteriostat, which inhibits microbial growth across repeated punctures. Plain sterile water for injection contains no preservative and is intended for single use only.
Do you ship internationally?
This SKU ships from our Canadian fulfillment facility to addresses within Canada. International availability varies by region — see our shipping policy for current routing.
What is the shelf life of an unopened vial?
Properly stored at room temperature in the original sealed vial, this product retains its specification for 24 months from the date of manufacture. The expiration date is printed on each vial.
