Preserved sterile water is supplied to qualified Canadian institutions as a laboratory diluent for in vitro sample preparation. The contents are sterile water with 0.9% benzyl alcohol as an antimicrobial preservative in a multi-dose container.

In vitro, benzyl alcohol limits bacterial growth after the septum is entered, which is why the solvent is used when a protocol requires repeated withdrawals from one vial. The preservative is not chemically inert toward every peptide: some sequences are incompatible with benzyl alcohol, so compatibility must be confirmed against the lot certificate of analysis and the receiving laboratory's method before the solvent is introduced into an assay. This listing describes a laboratory solvent only.

Identity references include CAS 7732-18-5 (water) and CAS 100-51-6 (benzyl alcohol). Store at controlled room temperature (20–25 °C). Discard according to the institution's multi-dose vial policy after first entry. Do not use where benzyl alcohol incompatibility is documented.

Lots are sourced from a GMP-aligned manufacturing partner and released as USP-grade water with 0.9% benzyl alcohol. Composition and related analytical results are documented on the lot certificate of analysis (COA). Retain the COA with the inventory record.
