COA included with every batch

Overview

What it is.

Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol, used across peptide research to reconstitute lyophilized powders for solution-based research applications.

Research Areas

  • Used to reconstitute lyophilized peptide research compounds
  • Preserved formulation supports multiple-use reconstitution over the vial's working life

Questions

Bacteriostatic Water FAQ

Why use bacteriostatic water instead of plain sterile water to reconstitute peptides?+

Bacteriostatic water is preserved with 0.9% benzyl alcohol, which supports safe multiple-use reconstitution across a vial's working life — plain sterile water is intended for single use and doesn't carry that preservative.

How do the different bottle sizes (3 ml / 10 ml / 30 ml) typically get used across a lab's supply needs?+

The larger multi-dose bottles (10 ml, 30 ml) reduce how many separate diluent containers a lab needs to keep on hand when reconstituting multiple compound vials, while the 3 ml size suits smaller, single-compound research runs.

How should bacteriostatic water itself be stored, and how long does it last once opened?+

Store it in a cool, dry place away from direct light. Once punctured, use it within 28 days; unopened shelf life is listed on the lot's Certificate of Analysis.

What testing does this batch undergo?+

Every batch is tested for sterility and endotoxin levels before release. The Certificate of Analysis for that lot ships with your order.
