BAC WATER

BAC Water (Bacteriostatic Water) is a sterile, non-pyrogenic diluent commonly referenced in laboratory workflows as bacteriostatic water and, in pharmaceutical labeling, as bacteriostatic water for injection. It is a water-based solution that contains benzyl alcohol as a bacteriostatic preservative (often described as 0.9% / 9 mg/mL where stated on label or documentation) and is typically supplied in a multi-dose vial format designed for repeated withdrawals using controlled sterile technique.

This product is supplied strictly as a research chemical / laboratory reagent for in-vitro and non-clinical laboratory research. It is not a pharmaceutical drug and is not intended for human or veterinary use, diagnosis, or treatment.

BAC Water (Bacteriostatic Water) – Research Diluent Overview

In research contexts, BAC water is valued as a controlled laboratory diluent for workflows that involve RUO materials and solution preparation under SOP. Search terms commonly associated with this product include bac water, bacteriostatic water, bacteriostatic water for injection, benzyl alcohol bacteriostatic preservative, and multi-dose diluent vial.

Main Features – Sterile Non-Pyrogenic Diluent with Benzyl Alcohol Preservative

• Sterile, non-pyrogenic diluent suitable for controlled research workflows (where stated on label/documentation)
• Benzyl alcohol preservative (commonly described as 0.9% / 9 mg/mL where stated on label or CoA/SDS)
• Multi-dose vial format designed for repeated withdrawals using appropriate sterile technique
• Clear, colorless solution for laboratory handling and visual inspection
• Documentation availability (e.g., SDS / lot information), depending on batch and format

Typical Laboratory Applications (RUO) – Peptide Research & Solution Preparation

In non-clinical research environments, bacteriostatic water is commonly referenced as a diluent for lyophilized peptide research workflows and general laboratory preparation tasks where controlled vial access is required. Common research-intent keywords include bacteriostatic water for peptides, bac water diluent, lyophilized peptide reconstitution, and research assay working solutions.

• Reconstitution of lyophilized peptides in research settings (per protocol and SOP)
• Preparation of short-term working solutions for lab assays and analytical workflows
• Protocols requiring controlled access to a multi-dose vial under sterile technique
• General research diluent use for RUO materials aligned with institutional SOP

Quality & Documentation – SDS, Lot Information, Label Verification

For consistent laboratory workflows, verify your vial’s label and any provided documentation (e.g., SDS, lot information) for key details such as preservative concentration, container type (multi-dose), and storage conditions. Pharmaceutical labeling commonly describes bacteriostatic water as sterile, non-pyrogenic water containing benzyl alcohol as a preservative and supplied in a multi-dose container; always treat the manufacturer label and documentation as the primary reference for the specific vial in your possession.

Storage & Handling – Research Context Guidelines (Follow Label + SOP)

• Store according to the product label. Many labeled products specify controlled room temperature (20–25°C).
• Use appropriate sterile technique to reduce contamination risk during vial access.
• Date the vial when first accessed and follow your lab SOP for beyond-use dating.
• As a widely used healthcare guideline for opened multi-dose vials, vials are commonly dated and discarded within 28 days after first puncture unless the manufacturer states a different timeframe. Always follow the manufacturer’s instructions for your specific vial.
• Discard if the solution becomes cloudy, discolored, or if particulate matter is present.
