Clinical Overview

Bacteriostatic Water (BAC Water) is a sterile aqueous diluent containing a low concentration of antimicrobial preservative for laboratory preparation and handling of research materials. It is utilized in controlled settings for reconstitution, dilution, and device/systemic flushing simulations where a preservative-containing water vehicle is required for short-term multi-entry use in research workflows.

Composition & Specifications

Components: Sterile water for research use with benzyl alcohol ~0.9% (v/v) as a bacteriostatic preservative.
Physicochemical: Clear, colorless solution; osmolality near water; pH monitored per lot to research-grade specifications.
Container/Closure: Multi-entry vial with elastomeric stopper designed for repeated puncture during the stated in-use period under aseptic technique.
Compatibility: Intended as a general diluent vehicle in bench-top and preclinical workflows; verify material compatibility with target analytes and device components prior to use.

Research Use & Handling

Use Case: Reconstitution/dilution of research materials, instrument priming, and procedural simulations where preservative-containing water is acceptable.
Asepsis: Employ aseptic technique at all times; disinfect septum prior to each access and minimize environmental exposure.
In-Use Period: Multi-entry use is limited to a short, defined window once vial sterility is first breached; discard remaining contents at the end of the in-use period per lab SOPs.

Purity & Quality Assurance

Revitalized Health solutions are prepared in controlled environments aligned to cGMP principles. Each BAC Water lot undergoes sterility testing, preservative content verification, HPLC identity/assay confirmation for benzyl alcohol, particulate examination, and endotoxin screening to research-grade limits. Batch Certificates of Analysis document methods, acceptance criteria, and results for traceability.

Storage & Stability

Store unopened vials at 20–25 °C (excursions 15–30 °C), protected from light. After first puncture, record open date/time and use within the lab-defined in-use period under aseptic conditions; keep vial tightly stoppered between withdrawals. Do not freeze. Discard if contamination, turbidity, or discoloration is observed.

Use & Testing

Identity: Bacteriostatic Water for Injection (WFI + 0.9% w/v benzyl alcohol), sterile, non-pyrogenic.
Use: Sterile diluent for reconstitution of compatible parenterals; multi-dose vial use supported by preservative (typ. discard within 28 days of first puncture). Not intended for direct IV infusion without appropriate admixture; avoid intrathecal use.
Analytics: Sterility per USP <71>; bacterial endotoxins (LAL) per USP <85> (e.g., NMT 0.25 EU/mL); preservative efficacy USP <51>; particulate matter USP <788>; TOC USP <643>; conductivity USP <645>; pH (typ. ~5.2–6.2). Labeling/Handling: Single clean puncture technique; swab septum; store controlled room temp; inspect visually—do not use if cloudy/particulate or seal compromised. Warnings: Do not use in neonates due to benzyl alcohol toxicity (“gasping syndrome”).
