What is bacteriostatic water for labs?

Research-use notice: This article summarizes published scientific literature for educational purposes. It is not medical advice and does not provide dosing, administration or human-use information. Findings described in the literature do not apply to any BlueNex Labs product, which is supplied only for in-vitro laboratory research and not for human or animal use.

Direct answer

Bacteriostatic water is sterile water with benzyl alcohol, listed here as a laboratory solvent. This note defines the material. It does not give mixing steps.

Scope

COA, quality & sourcing. How to read batch reports, compare supply channels, and document identity, purity, and endotoxin.

Bacteriostatic water Research Overview

Bacteriostatic water is sterile water with benzyl alcohol, used as a laboratory diluent for lyophilized research solids. The Hospira 30mL bottle is a separate catalog page.

This page provides laboratory-focused information for Bacteriostatic water. Content is intended for research use only and should be read with the published documentation and analytical data.

Diagram for the bacteriostatic water laboratory primer

Bacteriostatic water is sterile water that contains benzyl alcohol so a multi-puncture laboratory vial stays preserved after the first opening. That sentence is a solvent specification. It is not permission to prepare a material for human or veterinary use, and a diluent listing is not an administration kit.

What this page covers

This URL answers what the solvent is. Storage after a Canadian delivery is a different note: bacteriostatic water storage in Canada. For the manufacturer listing on this catalogue, see Hospira bacteriostatic water as a laboratory solvent. The historical slug is only the URL. Sealed-vial receiving for lyophilized solids is a separate note, peptide storage for Canadian laboratories.

This page does not list volumes, does not describe how to dissolve a solid, and does not compare solvents as a ranking. A laboratory SOP, if one exists, stays in the institution's own file.

Lot record

For the live shop URL, see Hospira bacteriostatic water, 30 mL. No certificate row is published for that bottle. A peptide Certificate of Analysis does not document the solvent. How to read a peptide COA applies to peptide lot files, not to this bottle.

Catalogue cross-reference

Milligram size does not apply to this bottle. Price and stock stay on the Hospira bacteriostatic water product page.

Orders ship inside Canada only after Interac e-Transfer checkout. Sold-out SKUs remain listed and cannot be added to the cart. Match each vial to its own Certificate of Analysis when a lot is published. Research use only. Not for human or veterinary use.
