Bacteriostatic Water 10ml | Peptide Reconstitution

Bacteriostatic Water is a sterile water preparation containing 0.9% benzyl alcohol as a preservative, allowing multiple withdrawals from a single vial without compromising sterility. It is the standard diluent used to reconstitute lyophilised peptide powders for research applications.

Specifications: Volume: 10ml | Preservative: 0.9% Benzyl Alcohol | Sterile, multi-dose vial

Compatible with the majority of research peptides including BPC-157, TB-500, GHK-Cu, Epithalon, CJC-1295, and more. Store at room temperature away from direct light after opening. UK-based stock, dispatched same day for orders placed before 4pm.

Sold strictly for laboratory and in-vitro research purposes only. Not for human or veterinary use.

Research Background

Bacteriostatic Water (BW) is a critical ancillary solution used in research laboratories for the reconstitution of lyophilised peptide compounds prior to in-vitro experimentation. The 0.9% benzyl alcohol content acts as a bacteriostatic preservative, inhibiting the growth of micro-organisms and permitting multiple withdrawals from the same vial over an extended research period — typically up to 28 days when stored correctly at 2–8°C.

Unlike standard water for injection (WFI), bacteriostatic water is specifically formulated for multi-dose use, making it the standard solvent of choice in peptide research protocols worldwide. Its compatibility with the majority of lyophilised peptide formulations ensures predictable reconstitution kinetics and stable solution concentrations throughout the research period.
