Our mission
Built on a simple principle
Researchers deserve a bacteriostatic water supplier they can actually trust. We do one product, label it plainly, test every lot and ship quickly so your work never waits on supplies.
What you can count on
Clear labelling
Every vial says exactly what is inside: purified water with 0.9% benzyl alcohol, the volume and the lot number.
Tested every lot
An independent third-party lab checks pH, benzyl alcohol content and recovery before a lot ships.
Nothing hidden
No proprietary blends and no vague claims. The Certificate of Analysis for each lot is on the product page.
