Product Overview
Bacteriostatic Water is a sterile, non-pyrogenic preparation of water for injection containing 0.9% benzyl alcohol added as a bacteriostatic preservative. It is utilized as a standard laboratory diluent for dissolving and

reconstituting lyophilized peptides, proteins, and chemical compounds across multi-dose research protocols.

Volume: 10 mL multi-dose vial
Preservative: 0.9% Benzyl Alcohol
Physical Form: Clear, colorless sterile liquid
pH Range: 4.5 – 7.0
Primary Application: Laboratory reconstitution and stabilization of lyophilized research compounds

Mechanistic & Functional Role in Research

Bacterial Growth Inhibition: The addition of 0.9% benzyl alcohol acts as a bacteriostatic agent, inhibiting the growth and proliferation of most Gram-positive and Gram-negative bacteria within the reconstituted solution.
Extended Compound Shelf Life: Unlike standard

sterile water (which must be discarded immediately after a single opening), bacteriostatic water allows for multiple syringe entries over a 28-day period while maintaining solution sterility in refrigerated storage.
pH Stabilization & Solubility: Formulated within an optimal pH range to prevent premature hydrolysis, conformational changes, or aggregation of sensitive peptide chains during reconstitution.

Handling and Storage Protocol

Usage: Swab the rubber stopper with isopropyl alcohol prior to each needle insertion. Inject the liquid slowly against the glass vial wall of the lyophilized compound to prevent foaming and shear stress on the peptide bonds.
Unopened Storage: Store at room temperature (15 degrees C to 25 degrees C); protect from

extreme heat and direct sunlight. Do not freeze.
Post-Entry Shelf Life: Once the vial seal is punctured, store at 2 degrees C to 8 degrees C and discard any remaining solution after 28 days.
