Format: Aqueous Solution
Unit Size: 2 mL
Product Overview
Bacteriostatic Water 2ml is a sterile, non-pyrogenic preparation of water for injection containing 0.9% (9 mg/mL) benzyl alcohol added as a bacteriostatic preservative. Specifically formulated as a universal diluent for the reconstitution of lyophilized peptides, proteins, and analytical chemical standards, this aqueous solvent prevents bacterial proliferation and contamination within multi-use research containers.
The addition of 0.9% benzyl alcohol inhibits the growth of most common Gram-positive and Gram-negative bacteria, fungi, and yeast, ensuring the stability and integrity of dissolved research compounds over extended multi-entry laboratory protocols.
Key Research Features & Highlights
Bacteriostatic Preservative System: Formulated with 0.9% Benzyl Alcohol to effectively suppress bacterial growth and maintain solution sterility during repeated vial penetrations.
0.22 µm Sterile Membrane Filtration: Fully sterile-filtered and pyrogen-tested to prevent contamination, endotoxin interference, or compound degradation upon reconstitution.
Extended Reconstituted Shelf Life: Preserves dissolved lyophilized peptide stability at 2°C – 8°C for up to 30 days after initial reconstitution.
Optimal pH Stability: Buffered to maintain a neutral-to-slightly-acidic pH (4.5 – 7.0), ensuring structural compatibility across a broad spectrum of sensitive peptide chains.
Convenient 2mL Volume: Ideal unit size for single-vial reconstitutions, minimizing solvent waste and preventing long-term solvent degradation.
Primary Applications in Laboratory Research
Peptide & Protein Reconstitution: Dissolving lyophilized research peptides, bioregulators, and growth factor standards for in vitro testing.
Multi-Entry Reconstitution Protocols: Maintaining solvent sterility during repeated sampling, serial dilutions, and micro-pipetting procedures.
Analytical Standard Preparation: Diluting high-purity chemical and biochemical assay standards requiring a sterile, preservative-containing liquid medium.
