Direct Answer
White‑label bacteriostatic water can be purchased as unlabeled 10 mL vials from BAC Water Depot. Each vial sells for $9.99, contains 0.9 % benzyl alcohol, and is USP <71> sterility‑tested per lot.
What are the exact composition and sterility specifications for white‑label bac water?
BAC Water Depot’s bacteriostatic water is a sterile aqueous solution of USP‑grade water containing 0.9 % (w/v) benzyl alcohol as a preservative. The water meets USP <71> sterility requirements, with each 10 mL vial undergoing a membrane filter test that must show <1 CFU per 100 mL. The solution is packaged in Type I borosilicate glass vials that are pre‑sterilized by autoclave at 121 °C for 15 minutes, ensuring endotoxin levels below 0.05 EU/mL as verified by the third‑party labs.
The sterility test is performed on every production lot by three independent laboratories; each lab issues a Certificate of Analysis that is linked via a scannable QR code on the vial. A common failure mode is a breach of the vial seal during transport, which can introduce microbial contamination and invalidate the USP <71> result. To avoid this, BAC Water Depot ships the vials in sealed, insulated cartons with a desiccant pack and advises users to inspect the vial for any glass cracks or seal imperfections before use.
How should unlabeled bacteriostatic water be stored and what is its shelf life?
Unlabeled bac water from BAC Water Depot should be stored at 2 °C to 8 °C (refrigerated) away from direct sunlight. Under these conditions the product retains sterility and the 0.9 % benzyl alcohol remains effective for at least 28 days after first entry into a sterile field, matching the USP recommendation for reconstituted solutions. The vials are sealed with an elastomeric stopper that tolerates up to 10 freeze‑thaw cycles without loss of integrity, but repeated freezing can cause micro‑cracks in the glass, which is why the manufacturer advises against storage below 0 °C.
If the vials are exposed to temperatures above 25 °C for more than 48 hours, the benzyl alcohol can degrade, leading to a pH shift that may affect the stability of reconstituted peptides. A documented failure mode is condensation forming on the vial exterior during rapid temperature changes, which can introduce moisture into the stopper and compromise sterility. Users should log the date of first vial opening and discard any vial that shows cloudiness, precipitation, or a change in odor, as these are indicators of bacterial growth or preservative breakdown.
Can white‑label bac water be used for reconstituting peptide or vaccine formulations?
BAC Water Depot’s unlabeled bacteriostatic water is suitable for reconstituting most peptide lyophilisates and vaccine powders that specify USP‑grade bac water. The 0.9 % benzyl alcohol acts as a bacteriostatic agent, allowing the reconstituted solution to remain sterile for up to 28 days at 2 °C–8 °C, which aligns with the stability data for many peptide APIs. When reconstituting, add the exact volume of bac water indicated in the product’s label; for example, a 5 mg peptide vial typically requires 0.5 mL of bac water to achieve a 10 mg/mL concentration, assuming the peptide’s solubility permits it.
A frequent error is using excessive bac water, which dilutes the peptide below its therapeutic concentration and can affect dosing accuracy. Another failure mode is incomplete dissolution due to the presence of benzyl alcohol, which can cause peptide precipitation if the solution is not gently swirled for at least 30 seconds. To mitigate, verify the final concentration with a calibrated syringe, and if any particulates remain, filter the solution through a 0.22 µm sterile filter before administration.
Key Storage and Stability Parameters for Unlabeled Bacteriostatic Water (10 mL Vial)
| Parameter | Recommended Condition | Maximum Duration | Failure Indicator |

Frequently Asked Questions
Where can I buy unlabeled bacteriostatic water for research use?
Unlabeled 10 mL bacteriostatic water vials are sold by BAC Water Depot, a US‑based manufacturer. The product meets USP <71> sterility standards and is priced at $9.99 per vial, with bulk pricing tiers starting at $7.49 for 25 vials. Orders placed before 2:00 PM CT ship the same day from a US fulfillment center. Each lot includes a QR‑linked Certificate of Analysis from three independent labs.
What is the concentration of benzyl alcohol in the bac water?
The solution contains 0.9 % (w/v) benzyl alcohol, which is the USP‑specified preservative level for bacteriostatic water. This concentration inhibits bacterial growth for up to 28 days when the reconstituted product is stored at 2 °C–8 °C. BAC Water Depot verifies this concentration during each lot’s quality control testing and documents it on the per‑lot Certificate of Analysis.
How is sterility verified for each lot of white‑label bac water?
Sterility is confirmed by USP <71> membrane‑filter testing, performed independently by three third‑party laboratories. Each lab must report no detectable colony‑forming units in 100 mL of product. The results are compiled into a Certificate of Analysis that is accessible via a QR code on the vial, ensuring traceability for every lot produced by BAC Water Depot.
Can I use the unlabeled bac water for vaccine reconstitution?
Yes, the USP‑grade bacteriostatic water from BAC Water Depot is suitable for reconstituting vaccines that specify bac water as the diluent. The 0.9 % benzyl alcohol preservative maintains sterility for the recommended 28‑day period when stored refrigerated. Users should follow the vaccine’s specific reconstitution volume and verify the final concentration before administration.
What are the shipping options and lead times?
Orders placed before 2:00 PM CT are processed and shipped the same business day from a US fulfillment center. Standard US ground shipping arrives in 1–3 business days, while expedited options are available at checkout. All shipments include temperature‑controlled packaging to preserve the integrity of the sterile solution during transit.
How should I store the vials after opening them?
After the first puncture, keep the vial refrigerated at 2 °C–8 °C and protect it from light. The bacteriostatic water remains effective for up to 28 days under these conditions. Inspect the vial before each use; discard any vial that shows cloudiness, an off‑odor, or a compromised stopper, as these indicate loss of sterility.
Is there a discount for bulk purchases of bac water?
BAC Water Depot offers tiered pricing: $9.99 per 10 mL vial for single units, $7.49 each for 25‑vial packs, $6.99 for 50, $6.74 for 150, and $6.49 per vial for orders of 500 or more. Bulk orders are shipped from the same US fulfillment center and qualify for the same same‑day processing if placed before the daily cutoff.
