Bacteriostatic Water 10ml (10 Vials / Kit)

Bacteriostatic Water at a glance

This listing is a laboratory supply, not an active compound. Bacteriostatic water consists of sterile, pyrogen-free water with 0.9% benzyl alcohol added to suppress bacterial growth, packaged in sealed vials with a rubber septum. It is the diluent most often paired with lyophilized peptides on GLP1 Forum Escrow, because the preservative lets a vial be punctured several times over the course of a project without the liquid becoming a source of contamination.

Price and availability

A kit of 10 vials at 10ml each from European Peptide Sciences, shipped from the Netherlands. It is listed at $89.00. As with every order here, the brand is paid only after you confirm delivery.

What it is studied for

There is no receptor pharmacology here. The relevant mechanism is the preservative: benzyl alcohol at this concentration is bacteriostatic, meaning it slows or halts bacterial multiplication rather than reliably killing every organism. It is thought to act by disturbing microbial cell membranes. That protection is useful when a stopper is entered repeatedly, but it does not sterilize contaminated material, and its activity against some fungi and spores is limited. Benzyl alcohol can also promote aggregation of certain proteins, which is why some materials specify preservative-free water instead.

Research and regulatory status

Bacteriostatic water has no research literature of its own in the sense that a peptide does. Its composition follows long-standing pharmacopeial monographs, and versions are marketed as pharmaceutical diluents. Product labeling carries a long-standing warning against use in newborns because of benzyl alcohol toxicity reported in that group. For catalogue purposes, the useful questions are sterility, preservative strength and packaging integrity rather than any form of efficacy.

Checking the lab data

A meaningful certificate for a diluent focuses on different tests than a peptide report. Expect sterility testing, a bacterial endotoxin result, and an assay confirming benzyl alcohol near 0.9%. pH, clarity and freedom from visible particles are routine checks. The vial seal and stopper should be intact, and the lot number and expiry date on the label should match the paperwork. There is no mass spectrometry identity test to expect here.
