About Bacteriostatic Water

USP-grade sterile diluent with 0.9% benzyl alcohol — the standard for reconstituting lyophilized research peptides.

Bacteriostatic Water for Injection is sterile water containing 0.9% (9 mg/mL) benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol inhibits microbial growth during multi-dose use, making it the standard diluent for lyophilized research peptides that need to remain stable in solution for days or weeks after reconstitution.

Unlike plain sterile water (which is single-use only after first puncture due to contamination risk), bacteriostatic water can be used for multiple withdrawals over up to 28 days while refrigerated — making it the practical choice for research peptide workflows.

Frequently asked questions

Why not use plain sterile water?

Plain sterile water has no preservative — once the vial is punctured, microbial contamination can occur within hours. Bacteriostatic water's 0.9% benzyl alcohol allows safe multi-dose use for up to 28 days post-puncture.

Is REVIVE bacteriostatic water USP grade?

Yes — supplied to USP standards for sterile water with bacteriostatic preservative. Each lot ships with a certificate confirming sterility and benzyl alcohol concentration.

How much do I need per peptide vial?

Typical reconstitution volumes range from 1–5 mL depending on peptide. The 3 mL vial suits a single 5–10 mg peptide vial; the second vial in the box covers a further reconstitution for reconstituting several vials or for ongoing multi-vial research use.

Is bacteriostatic water included with the packs?

Yes — every boxed pack in the catalogue includes one 3 mL bacteriostatic water vial in the same carton. This product adds two further vials for additional reconstitution.
