Authentic Hospira 30 mL vials can be verified through several manufacturing-specific markers. The flip-top cap is produced via a blow-fill-seal process with distinct beveled edges. The lot number and expiry date are heat-stamped directly into the plastic vial body—not applied as an inkjet label—making them resistant to abrasion. The printed label carries the Pfizer/Hospira trade dress with NDC 0409-3977-03 in machine-readable GS1-128 barcode format.
Unopened vials should be labd at controlled room temperature, 20°C to 25°C (68°F to 77°F). Protect from light. USP <797> and CDC multi-dose vial policy require that once a vial is first punctured, it must be date-labeled and discarded within 28 days, regardless of the remaining volume. The bacteriostatic agent does not provide indefinite protection against contamination.

Pfizer Bacteriostatic Water 30ml — Sterile USP-Grade Diluent for Peptide Reconstitution
This 30ml vial of Bacteriostatic Water is the standard-size solvent used for reconstituting lyophilized research peptides, dissolving research compounds, and general laboratory dilution work. The 30ml format is widely regarded as the practical ground — it is the size most commonly specified in reconstitution protocols mid-volume applications. Mountainside Medical
What makes it “bacteriostatic”
This vial contains sterile water for injection (USP) preserved with 0.9% benzyl alcohol (NF) — the United States Pharmacopeia specification for multi-use parenteral preparations. Benzyl alcohol functions as a bacteriostatic preservative by disrupting bacterial cell membrane integrity and interfering with membrane-associated transport processes, preventing colonization of the solution. This is what allows the vial to be safely punctured and drawn from multiple times, unlike standard sterile water for injection, which is preservative-free and designed for single-use injection only.

Product specifications
Bacteriostatic Water for Injection, USP is a sterile, nonpyrogenic preparation of water for injection containing 0.9% (9 mg/mL) of benzyl alcohol added as a bacteriostatic preservative, with a pH of 5.7 (4.5 to 7.0). It is sterilized using a 0.22 µm filtration process under aseptic fill conditions. At this concentration, the vial supports repeated withdrawals for up to 28 days under proper aseptic handling. DailyMed + 2
Why it’s preferred for peptide work
Bacteriostatic water is the preferred solvent for dissolving peptide structures, as it maintains the correct pH balance to prevent peptide degradation, or denaturing, during reconstitution. It serves as the standard reconstitution solution for a wide range of lyophilized research peptides, supporting multi-dose research preparations and stable peptide solution preparation throughout a research protocol. ONYX BIOLABSPalmettopeptides
How to use
When drawing the solution for peptide reconstitution, invert the vial and insert the needle through the center of the stopper, drawing slowly to the desired volume since rapid withdrawal creates air bubbles that compromise measurement accuracy. Inject the solvent into the peptide vial along the inside glass wall rather than directly onto the lyophilized powder, then swirl gently in a circular motion until the powder dissolves completely — do not shake, vortex, or invert vigorously, as mechanical agitation can denature peptide secondary structure.

Storage and handling
Store at room temperature (15–25°C) and limit exposure to extreme temperatures that may affect the product. Always check the expiration date before use, and discard the vial if the solution appears discolored or contains particles. Canvax Reagents SLCanvax Reagents SL

Ryan –
I recently purchased the 30ml Bacteriostatic Water from bacteriostaticwaterlab and I’m very happy with the purchase. The bottle arrived with authentic Hospira packaging — everything looked exactly as expected, with clear labeling and no signs of tampering.
What stood out most was the batch number printed on the bottle, which I was able to verify independently. That gave me real confidence that this was a legitimate, unaltered product and not a repackaged or counterfeit item, which is unfortunately common with this type of product online.
The bottle was well-sealed, shipping was handled carefully, and the product itself has been exactly as described. For anyone hesitant about ordering bacteriostatic water online, this seller delivers the real thing. Will be ordering from bacteriostaticwaterlab again.
