Best Bacteriostatic Water For Injection

What are the quality‑control specifications for BAC Water Depot bacteriostatic water?

Every lot of BAC Water Depot’s bacteriostatic water is accompanied by a Certificate of Analysis that documents USP <71> sterility testing via 14‑day membrane filtration, USP <85> bacterial endotoxin testing with a limit of ≤ 0.25 EU/mL, and USP <51> bacteriostatic effectiveness classified as Category 1B. The independent third‑party laboratory also verifies benzyl alcohol content by HPLC‑UV (0.90 % ± 5 %) and confirms identity, pH, subvisible particulates, and container integrity per USP <791>, <788>, and <1207> respectively. Any deviation triggers a lot‑rejection and a new CoA is generated, ensuring that only compliant vials reach the customer. A common failure mode in bacteriostatic water production is microbial DNA contamination that can evade culture‑based sterility tests. BAC Water Depot mitigates this risk by employing a validated PCR assay for microbial DNA, reporting “no detectable microbial DNA” on each CoA. If DNA is detected, the lot is quarantined and re‑tested until it meets the strict zero‑detectable threshold, preventing compromised vials from being shipped.

How is BAC Water Depot bacteriostatic water packaged and what are the storage requirements?

The product is supplied in 10 mL Type I borosilicate multi‑dose vials with tamper‑evident closures, designed for repeated puncture without compromising sterility. The vials are manufactured in an ISO 9001:2015‑registered U.S. facility and each lot undergoes container‑integrity testing (USP <1207>) to verify that the seal remains intact after multiple accesses. Unopened vials should be stored at controlled room temperature 15–30 °C, out of direct sunlight, with no refrigeration or cold‑chain shipping required. The label and the CoA both list the expiration date, after which the vial must be discarded regardless of appearance. Once a vial is punctured, the recommended storage condition changes: refrigerate at 2–8 °C and discard after 28 days. Failure to refrigerate after opening can lead to loss of bacteriostatic effectiveness, allowing bacterial growth despite the presence of 0.9 % benzyl alcohol. Users who exceed the 28‑day window risk contamination that may not be detected by routine visual inspection, so strict adherence to the post‑puncture storage rule is essential for maintaining product integrity.

What shipping options and timelines does BAC Water Depot provide for researchers in the United States?

Orders placed before 2:00 PM Central Time, Monday through Friday, ship the same business day from the Dallas, TX fulfillment center via USPS Priority Mail, which the carrier estimates will arrive in 1–3 business days. Standard shipping costs a flat $15.99, but orders over $250 (up to 100 vials) qualify for free standard shipping. For larger case orders exceeding 100 vials, a $34.99 flat rate applies regardless of weight, ensuring predictable costs for bulk purchasers. For researchers who need the product more quickly, an Express option is available at checkout. USPS Priority Mail Express is priced at $45.99 or $1.50 per vial, whichever is higher, and typically delivers the next business day to most U.S. addresses, with a two‑business‑day guarantee for more remote locations. The service does not promise next‑day delivery for every address, and no cold‑chain handling is involved; the product remains stable at room temperature during transit.
