Hospira Bacteriostatic WaterSterile Laboratory Solution · Lot-Traced

Bacteriostatic water is sterile water with a preservative (0.9% benzyl alcohol) added — the standard reconstitution solvent for freeze-dried research peptides. Unlike plain sterile water, it prevents bacterial growth after the vial is opened, so you can dip in multiple times over 28 days.

ProSource Labs supplies Hospira Bacteriostatic Water in the following available vial sizes for research purchase: 5mL, 10mL. Product SKU references: BACWAT-5ML, BACWAT-10ML.

• Reconstitution Standard: The universal solvent for freeze-dried peptide vials
• Multi-Use: 28-day post-opening usable window thanks to the preservative
• Preservative: 0.9% benzyl alcohol — bacteriostatic, not bactericidal
• Room Temperature Stable: No refrigeration required — store 15-30°C

Each vial is sealed under sterile conditions in the source manufacturer's cGMP facility (for pharmaceutical-grade solutions like Hospira Bacteriostatic Water) or in a validated laboratory environment for laboratory-grade reagents. Vials are visually inspected for particulate matter and seal integrity before release.

Storage: Store at room temperature (15–30°C), tightly capped.

Because Hospira Bacteriostatic Water is a liquid, freezing is not appropriate — freeze-thaw cycles can compromise the vial's seal, alter the concentration through water-ice expansion damage, and (for preserved solutions) can affect preservative distribution. Store the sealed vial upright.

All laboratory handling should follow the receiving institution's standard operating procedures for sterile reagents. Once a vial's rubber septum has been punctured, the contents should be treated per the corresponding manufacturer's product monograph.

Because Hospira Bacteriostatic Water is a liquid reagent rather than a synthetic peptide, HPLC purity testing is not the relevant analytical method. Quality documentation for this product covers the manufacturer's certificate of sterility, endotoxin testing, fill-volume verification, and (for preserved products) preservative concentration analysis.

For pharmaceutical-grade products supplied through ProSource Labs (such as Hospira Bacteriostatic Water for Injection), the underlying manufacturer's FDA-approved product monograph is the authoritative reference for composition, storage, and in-use timelines. Request the source documentation from customer support after purchase if required for your institution's incoming QA workflow.

Standard laboratory diluent for reconstituting freeze-dried peptide research SKUs. The 0.9% benzyl alcohol preservative keeps the reconstituted solution viable across repeated withdrawals for up to 28 days.

Hospira Bacteriostatic Water vials ship in tamper-evident, moisture-resistant, cold-chain-friendly outer packaging from our Southern California distribution facility for fast US domestic delivery — typically 2-4 business days coast-to-coast, with expedited options available at checkout.

Every Hospira Bacteriostatic Water shipment is discreet — the outer packaging carries no product-specific branding or direct reference to the compound name inside, protecting researcher privacy. Tracking numbers are emailed automatically. For institutional or high-volume orders, dedicated wholesale pricing is available through the wholesale portal.
