Where can I buy BAC water (bacteriostatic water) for research use

Where can I buy bacteriostatic water for research?

BAC Water Depot provides online ordering directly to researchers worldwide, with a secure HTTPS storefront that lists current inventory and pricing. The site displays real‑time stock levels for single vials, 10‑packs, and bulk quantities, allowing you to select the exact quantity needed for a project. Payments are accepted via major credit cards and PayPal, and a per‑lot Certificate of Analysis is linked via QR code on each vial label, ensuring traceability. Common ordering issues include mismatched shipping addresses; double‑checking the fulfillment address prevents delays, especially for time‑sensitive experiments.

All shipments originate from a US fulfillment center in Dallas, Texas, and are dispatched the same business day for orders placed before 2:00 PM Central Time, Monday through Friday. The carrier provides tracking numbers that update in real time, so you can monitor delivery progress. Occasionally, carriers may experience regional delays due to weather or high volume; contacting the carrier with the tracking number can resolve most delivery exceptions. Because the product is non‑refrigerated, it tolerates standard parcel handling without cold‑chain requirements.

What specifications should I verify when purchasing bacteriostatic water?

The most critical specifications are sterility, endotoxin level, and benzyl alcohol concentration. Each lot from BAC Water Depot undergoes USP <71> sterility testing via 14‑day membrane filtration, USP <85> LAL testing with an endotoxin limit of ≤ 0.25 EU/mL, and HPLC‑UV analysis confirming benzyl alcohol at 0.90 % ± 5 %. The Certificate of Analysis also records pH, subvisible particulates (USP <788>), and container integrity (USP <1207>). A frequent failure mode is a mismatch between the printed lot number and the QR‑code link; verify both before use to ensure the correct CoA is referenced.

In addition to chemical purity, the physical container matters. BAC Water Depot uses Type I borosilicate multi‑dose vials with tamper‑evident closures, meeting USP <791> for pH and USP <788> for particulate limits. The vials are rated for up to 25 punctures, but repeated needle insertions can compromise the seal, leading to contamination. To avoid this, use a new sterile needle for each access and discard the vial after 28 days once opened, as recommended on the label. Monitoring for cloudiness or precipitate after opening can also flag degradation.

How is bacteriostatic water stored and what are the stability limits?

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 Certificate of Analysis list the expiration date, after which sterility cannot be guaranteed. Keep the vials in their original packaging until needed to maintain the specified environment.

Once a vial is punctured, it must be refrigerated at 2–8 °C and used within 28 days, after which it should be discarded. Failure to refrigerate after opening can allow bacterial growth despite the presence of benzyl alcohol, especially if the vial is repeatedly accessed. Inspect the vial for any loss of seal integrity or particulate formation before each use; such signs indicate that the product may no longer meet USP <71> sterility criteria and should be replaced.
