Who Sells Bacteriostatic Water

Where can I buy bacteriostatic water for laboratory research?

BAC Water Depot offers direct online ordering of bacteriostatic water, shipping from a Dallas, TX fulfillment center. Orders placed before 2:00 PM CT Monday‑Friday are dispatched the same business day via USPS Priority Mail, typically arriving in 1–3 business days. Bulk pricing tiers start at $6.49 per vial for orders of 500 vials or more, and free standard shipping applies to purchases over $250 up to 100 vials. Customers should verify the lot number on the Certificate of Analysis to confirm sterility and endotoxin limits before use.

When purchasing, ensure the product meets USP <71> sterility (no growth after 14‑day membrane filtration) and USP <85> endotoxin limits (≤ 0.25 EU/mL). A common failure mode is compromised container integrity; USP <1207> testing confirms seal performance. If a vial shows visible particulates beyond USP <788> limits, discard it and request a replacement, as such contamination can affect downstream assays.

How is bacteriostatic water quality verified at BAC Water Depot?

Each production lot undergoes independent third‑party testing for multiple parameters: sterility (USP <71>), bacterial endotoxin (USP <85> LAL ≤ 0.25 EU/mL), microbial DNA by validated PCR (no detectable DNA), and bacteriostatic effectiveness (USP <51> Category 1B). The Certificate of Analysis, accessible via a QR code on the vial, lists the exact results and includes HPLC‑UV verification of benzyl alcohol content (0.90 % ± 5 %). These data are archived for traceability, allowing researchers to match assay requirements with documented lot performance.

In addition to chemical and microbiological tests, physical assessments such as pH (USP <791>), subvisible particulates (USP <788>), and container integrity (USP <1207>) are performed. A frequent issue is deviation in pH outside the 6.0–8.0 range, which can reduce the efficacy of the bacteriostatic agent; such lots are rejected during QC. The comprehensive testing regime ensures that every vial meets stringent research standards before shipment.

What are the storage and handling requirements for BAC Water Depot’s bacteriostatic water?

Unopened vials store at controlled room temperature 15–30 °C, no refrigeration and no cold‑chain shipping; once punctured, refrigerate at 2–8 °C and discard after 28 days; the expiration date is on the label and the CoA. The product’s glass composition (Type I borosilicate) provides chemical resistance, but exposure to direct sunlight can degrade benzyl alcohol concentration over time, so storage away from UV sources is recommended.

During handling, use a sterile needle and aseptic technique to avoid introducing contaminants; a common failure is breach of the tamper‑evident closure, which can allow microbial ingress and invalidate USP <71> sterility. If the vial shows any cloudiness, particulate matter, or compromised seal, it should be quarantined and a new lot requested. Proper refrigeration after first puncture preserves bacteriostatic activity for the full 28‑day period.
