Bacteriostatic Water

Bacteriostatic Water

Laboratory Grade Bacteriostatic Solvent & Preparation Reagent

Product Overview

Bacteriostatic Water is a highly purified, sterile preparation of water for injection containing 0.9% benzyl alcohol (C7_H8_O) added as a bacteriostatic preservative. In laboratory and preclinical settings, it serves as a chemically defined solvent designed for the repeated withdrawal of contents from a multi-dose container. This reagent is an essential tool for the reconstitution of lyophilized research compounds, ensuring the inhibition of microbial growth and maintaining the integrity of sensitive peptide solutions during extended investigative workflows.

Key Research Applications

• Peptide Reconstitution Modeling: Used in experimental workflows to transform lyophilized powders into stable, aqueous solutions for precise volumetric dosing.

• Microbial Growth Inhibition: Targeted in studies requiring a sterile environment, where the benzyl alcohol component prevents the proliferation of bacteria in multi-use vials.

• Solubility & Stability Research: Utilized to investigate the long-term structural integrity of various research molecules when stored in a bacteriostatic aqueous medium.

• Analytical Assay Preparation: Frequently employed as a high-purity vehicle for delivering compounds in both in vitro cell culture studies and in vivo animal modeling.

• Multi-Dose Sampling Evaluation: Evaluated for its effectiveness in maintaining reagent sterility across multiple access points in a standardized laboratory environment.

Why Researchers Choose Bacteriostatic Water

• Preservative-Enhanced Longevity: The inclusion of 0.9% benzyl alcohol allows reconstituted compounds to remain viable for research use for up to 28 days when stored correctly.

• High Analytical Purity: Processed through rigorous filtration and distillation to meet the stringent requirements of sensitive laboratory assays.

• Optimized pH Balance: Formulated with a slight acidity (typical pH 4.5–7.0) to maintain the chemical stability of many synthesized peptides and small molecules.

• Standardized Research Vehicle: Provides a consistent, reproducible solvent profile that minimizes variables in pharmacokinetic and pharmacodynamic modeling.

Storage & Handling Guide

To ensure the long-term stability and reproducibility of your experimental results, please follow these standardized laboratory protocols for Bacteriostatic Water:

I. Long-Term Storage (Unopened)

• Temperature: Store at controlled room temperature (20°C to 25°C).

• Environment: Keep in a cool, dry place away from direct light. Ensure the seal remains intact to guarantee sterility until use.

II. Usage & Reconstitution Protocol

• Aseptic Technique: Clean the rubber stopper with a 70% isopropyl alcohol swab before each entry to maintain a sterile environment.

• Mixing: When using to reconstitute peptides, allow the water to flow slowly down the side of the vial to avoid foaming or denaturing the compound.

III. Storage of Opened Vials

• Duration: Once the vial has been punctured, the remaining solution must be used within 28 days.

• Disposal: Any remaining solution after 28 days should be discarded according to standard laboratory biohazard or chemical waste protocols.

Research Use Only: This compound is intended for in vitro laboratory research and animal imaging studies. It is not for human or clinical use.
