Bacteriostatic Water vial

What is Bacteriostatic Water?

Bacteriostatic Water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is the standard diluent used to reconstitute lyophilized research peptides — the preservative allows the multi-dose vial to remain usable across multiple punctures within its stability window.

Each vial contains 10 mL of bacteriostatic water, manufactured under sterile conditions and quality-controlled per batch.

For research use only. Not for human consumption.

Frequently asked.

What is Bacteriostatic Water?

Bacteriostatic Water is sterile water with a 0.9% benzyl alcohol preservative. It is the standard diluent for reconstituting lyophilized research peptides — needed for nearly every vial-format compound in our catalog. Sold for research use only.

How is purity verified?

Every lot of Bacteriostatic Water is independently tested by Chromate Laboratories before release. We verify identity, purity (≥99%), and endotoxin levels. A Certificate of Analysis for your specific lot is available on request — just email admin@nxtstate.co with your order number.

How should it be stored?

Store the sealed vial at room temperature (15-30°C), away from direct light. Once punctured, the vial remains usable within the standard stability window for bacteriostatic preparations.

What does each shipment include?

Each order ships with the Bacteriostatic Water unit(s) you purchased. Reconstitution materials (bacteriostatic water, syringes, alcohol pads) are available as separate products. We recommend ordering them together if it’s your first shipment.

How fast does it ship?

Orders placed before 2pm ET ship same-day. After that, next business day. All shipments include tracking, and you’ll receive an email the moment your order is on the way. Free shipping on orders over $200.

Where is it manufactured?

Bacteriostatic Water is compounded at facilities operating under GMP-aligned standards. We work exclusively with manufacturers who allow third-party lab verification of every batch we release.
