What’s in the vial
A 30 mL vial of sterile water preserved with 0.9% benzyl alcohol, used as a diluent and reconstitution solvent in laboratory research and analytical applications.
The rubber-stopper closure is built for repeated access under proper aseptic technique, and the preservative is what makes that repeat access possible.

Product Questions
What laboratory buyers ask about the vial itself — composition, access, and packaging.
See all questions →What exactly is in each vial?
Each 30 mL vial contains sterile water preserved with 0.9% benzyl alcohol. Nothing else is added, and the composition is verified on the current lot's published COA.
What is the difference between bacteriostatic water and sterile water?
Plain sterile water contains no preservative and is intended for single access. Bacteriostatic water adds 0.9% benzyl alcohol, which suppresses bacterial growth so the vial can be accessed repeatedly with proper aseptic technique in laboratory settings.
Can a vial be accessed more than once?
Yes. The rubber stopper is designed for repeated access with proper aseptic technique, and the benzyl alcohol preservative suppresses bacterial growth between accesses.
Where does this product come from?
BacterioWater is an independent laboratory supplier, not the manufacturer. Each lot is manufactured and filled by a third-party facility and tested by an independent laboratory; we stock the finished vials and publish the certificate for the lot currently shipping.
How is my order packaged?
Orders ship in protective packaging with vials padded for transit. Every vial is sealed and lot-labeled, so it can be matched to its published certificate on arrival.
