Description
Overview
Bacteriostatic Water (BAC Water) is a USP-grade sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol inhibits microbial growth, allowing for multiple withdrawals from a single vial while maintaining sterility — a critical advantage over single-use sterile water for researchers working with lyophilized peptides over extended research protocols.
Laboratory Applications
- Reconstitution of lyophilized research peptides
- Multi-use diluent for serial research preparations
- Vehicle control in peptide research experiments
- Compatible with standard borosilicate glass and polypropylene labware
Specifications
- Grade: USP (United States Pharmacopeia)
- Preservative: 0.9% Benzyl Alcohol
- Sterility: Sterile-filtered, aseptically processed
- Endotoxin: <0.25 EU/mL
- pH: 4.5–7.0
- Packaging: Sealed glass vial with rubber stopper and flip-cap
- Storage: Store at room temperature (15–30°C). Protect from light. Do not freeze
Usage Notes
- Use aseptic technique — swab stopper with alcohol before each withdrawal
- Use within 28 days of first puncture for optimal sterility
- Do not use if solution appears cloudy or contains particulates
- Discard if seal integrity is compromised
