Bacteriostatic Water research overview
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, a preservative that inhibits microbial growth inside an opened vial. TrueBond Labs carries it in two laboratory formats — a 10 mL vial and a larger 30 mL vial — as the standard diluent for reconstituting the lyophilized research peptides in our catalog. Unlike the peptides themselves, this solution stores at room temperature, and each lot is coded so its documentation can be traced at /lab-reports.
In routine bench practice, a measured volume of bacteriostatic water is drawn from the vial and introduced into a lyophilized peptide vial to return the powder to solution for in-vitro work. Because the benzyl alcohol preservative suppresses bacterial proliferation, the septum-sealed vial tolerates a series of withdrawals over the course of a research project — something plain preservative-free sterile water is not formulated to support.
Many researchers add bacteriostatic water and 21G Luer-lock mixing syringes to a peptide order so the full reconstitution workflow arrives in one shipment. Because the preservative is already in solution, no cold chain is involved for this item; vials are simply kept at room temperature and opened at the point of use. The current lot, TB-BAC-001, is cataloged at /lab-reports with the rest of the lot documentation — HPLC purity metrics do not apply to a diluent, so the record tracks lot identity and dating instead.

Bacteriostatic Water — frequently asked questions
What is bacteriostatic water used for?+
In a laboratory setting, bacteriostatic water serves as the diluent that returns lyophilized research peptides to solution before in-vitro use. It is sterile water with 0.9% benzyl alcohol added as a preservative. TrueBond Labs supplies it in 10 mL and 30 mL vials alongside its research peptide catalog, for research applications only.
What is the difference between bacteriostatic water and sterile water?+
The benzyl alcohol. Bacteriostatic water contains 0.9% benzyl alcohol, which holds back microbial growth after the vial's septum is first punctured, so a single vial can support multiple laboratory withdrawals. Preservative-free sterile water offers no such protection and is generally treated as single-use once opened.
How should bacteriostatic water be stored?+
Room temperature is sufficient — no freezer or refrigerator is required for the unopened vial, which sets it apart from the lyophilized peptides it accompanies. Keep it sealed until needed and handle it with sterile technique at the bench. Note that peptide solutions prepared with it still require 2–8°C refrigeration.
What sizes of bacteriostatic water does TrueBond Labs sell?+
Two formats are available: a 10 mL vial suited to smaller reconstitution runs and a 30 mL vial for laboratories working through peptides at higher volume. Both are sterile 0.9% benzyl alcohol solutions, both are eligible for bundle pricing, and both ship the same business day when ordered before the weekday cutoff.
