BW10 — Bacteriostatic Water 10mL
Sterile bacteriostatic water vials for research peptide reconstitution. Supplied in boxes of 10 vials. Free shipping on all orders.
What Is Bacteriostatic Water?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. The benzyl alcohol acts as a bacteriostatic agent — it inhibits the growth and reproduction of bacteria without necessarily killing them outright. This distinguishes bacteriostatic water from standard sterile water for injection, which offers no antimicrobial protection once the seal is broken.
In laboratory research settings, bacteriostatic water is the standard reconstitution solvent specified in peptide research protocols because it allows a single vial to be accessed multiple times while maintaining solution sterility. Once a lyophilised peptide vial is reconstituted, the resulting solution typically requires refrigeration and is consumed across multiple research sessions — the benzyl alcohol preservative maintains the integrity of the reconstituted solution during this period.
For laboratory research use only. Refer to individual research protocols for specific reconstitution volumes and storage requirements.
Using Bacteriostatic Water in Research Protocols
Standard lyophilised peptide vials from Eternal Peptides Wholesale are supplied as dry powder and must be reconstituted before use. The general approach specified in most published research protocols:
BW10 + BPC-157 + TB-500 Blend
Most researchers using BPC-157 or TB-500 compounds order bacteriostatic water alongside their peptide vials. BW10 (10mL) is compatible with all lyophilised peptide vials in the Eternal Peptides Wholesale range. For research use only.
Frequently Asked Questions
What is bacteriostatic water?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative. The benzyl alcohol inhibits bacterial growth, allowing the vial to be accessed multiple times without contamination — unlike single-use sterile water. In research settings, it is the standard solvent specified for reconstituting lyophilised peptide powders. For laboratory research use only.
Why is bacteriostatic water used for peptide reconstitution?
Lyophilised peptide powders must be reconstituted into solution before research use. Bacteriostatic water is preferred because the 0.9% benzyl alcohol preservative inhibits bacterial growth after the vial seal is broken, maintaining solution sterility across multiple withdrawals over the reconstituted vial's life. For research use only.
How much bacteriostatic water do I need per peptide vial?
The volume depends on the target concentration specified in your research protocol. One 10mL BW10 vial is sufficient for multiple peptide vial reconstitutions in most standard protocols. Always follow the specific volumes specified in your approved research protocol. For research use only.
Where can I buy bacteriostatic water in Australia for research?
