Product Questions
What buyers ask about the vial itself — composition, access, and packaging.
See all questions →What exactly is in each vial?
Each 30 mL multi-dose 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 a multi-dose vial can be accessed repeatedly with proper aseptic technique in research settings.
Can a vial be accessed more than once?
Yes — it is a multi-dose vial. The rubber stopper is designed for repeated access with proper aseptic technique, and the benzyl alcohol preservative suppresses bacterial growth between accesses.
How is my order packaged?
Orders ship in plain packaging with vials padded for transit — no product description appears on the outside of the box.
