what is bacteriostatic water?
Bacteriostatic Water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. Verve supplies it as a laboratory reagent for research use only, not for human or veterinary use. It is catalogued under longevity & cellular as a sterile preserved laboratory diluent.
Bacteriostatic water is not a peptide but a laboratory reagent: sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol inhibits the growth of common contaminating organisms, which allows a sealed vial to be accessed more than once over the course of a study without the reagent itself becoming a source of microbial contamination.
In research settings it serves as the standard diluent for reconstituting lyophilized compounds and for preparing working dilutions from a stock, where consistent solvent quality is a prerequisite for reproducible concentration calculations. Verve's bacteriostatic water is sourced in the United States, produced under sterile conditions, and quality-checked lot by lot, with documentation supplied alongside the product.

how pure is bacteriostatic water?
purity, third-party testing & the certificate of analysis
Every batch of verve Bacteriostatic Wateris synthesized and vial-filled in the United States and screened by an independent, accredited laboratory. Chromatographic purity and quantity are measured by HPLC-UV/VIS; where the panel includes them, endotoxin is screened by LAL and sterility by USP <71>, with the sterility result reported as no growth detected or as pending while the culture is still running. Products are manufactured to a 99%+ purity standard where stated.
Published certificates for the lots currently in our COA library cover part of the range; a published report for this compound is not in the library yet. Orders placed Monday–Friday ship by 2pm CT, free over $100, with damage protection in transit and full US tracking.

What is bacteriostatic water?
It is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. Verve supplies it as a laboratory reagent for research use only, not for human or veterinary use.
What is it used for in research?
It is used as a diluent for reconstituting lyophilized research compounds and for preparing working dilutions from stock solutions in a laboratory setting.
How is it different from sterile water?
Plain sterile water contains no preservative and is generally treated as single-access. The benzyl alcohol in bacteriostatic water inhibits microbial growth, which is why it is chosen for multi-access laboratory workflows.
Is documentation included?
Yes. It is US-sourced, produced under sterile conditions, and quality-checked by lot, with lot-level documentation supplied with the order.
