Common questions
What is bacteriostatic water?
Sterile water with 0.9% benzyl alcohol added. The benzyl alcohol slows the growth of bacteria, so a sealed multi-use vial can be entered more than once in laboratory work.
Is it the same as sterile water?
No. Sterile water has nothing added and is meant for single use once opened. Bacteriostatic water contains 0.9% benzyl alcohol as a preservative.
Does it come with a certificate?
It is a consumable, so it has no HPLC certificate like our peptides. Each vial carries its batch number and expiry date from the manufacturer.
How should it be stored?
Sealed, at room temperature, away from light, and used before the expiry date on the label.
Is it for human use?
No. It is sold for laboratory use only, like everything in our store.
