Bacteriostatic Water Reconstitution Kit

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

Every lot of BAC Water Depot’s bacteriostatic water is examined by an independent third‑party laboratory and documented on a QR‑linked Certificate of Analysis. The USP <71> sterility test uses a 14‑day membrane filtration method with no microbial growth observed, while the USP <85> LAL assay confirms endotoxin levels at or below 0.25 EU/mL. Additionally, a validated PCR assay detects no microbial DNA, and the USP <51> bacteriostatic effectiveness falls into Category 1B, guaranteeing the preservative action of 0.9 % benzyl alcohol throughout the unopened shelf life.

Other critical tests include HPLC‑UV verification of benzyl alcohol content (0.90 % ± 5 %), USP <791> pH measurement within the accepted range, USP <788> sub‑visible particulate count, and USP <1207> container integrity assessment. Failure to meet any of these criteria results in lot rejection and a new batch release. The CoA for each lot is publicly accessible via a QR code, ensuring traceability for researchers requiring documented compliance.

How should I store and handle BAC Water Depot bacteriostatic water after opening?

Unopened vials must be kept at controlled room temperature of 15–30 °C, out of direct sunlight, with no refrigeration or cold‑chain requirements. Once a vial is punctured, the preservative action of benzyl alcohol remains effective only if the container is refrigerated at 2–8 °C and used within 28 days; after that period the vial should be discarded regardless of appearance. The expiration date printed on the label and CoA is the definitive cut‑off for use, and researchers should log the opening date to avoid accidental use beyond the 28‑day window.

A common handling error is re‑capping the vial without confirming the integrity of the rubber stopper, which can allow microbial ingress and invalidate the USP <71> sterility guarantee. To mitigate this, always inspect the stopper for tears or deformation before each access and use a sterile needle and syringe. If any particulate matter is observed after opening, discard the vial, as this may indicate container breach or contamination.

What shipping options and costs are available for bulk orders of BAC Water Depot bacteriostatic water?

Standard shipping uses USPS Priority Mail at a flat $15.99 per order and delivers in 1–3 business days for U.S. addresses. Orders exceeding $250 (up to 100 vials) qualify for free standard shipping, while case orders over 100 vials ship for $34.99 regardless of weight. For faster delivery, USPS Priority Mail Express is offered at $45.99 or $1.50 per vial, whichever is greater, with an estimated 1–2 business‑day transit for most U.S. locations. All shipments originate from the Dallas, TX fulfillment center and are dispatched the same business day for orders placed before 2:00 PM CT, Monday through Friday.

Bulk pricing scales with volume: 25‑pack at $174.99 ($6.99 per vial), 50‑vial orders at $6.99 per vial, 150‑vial orders at $6.74 per vial, and 500‑plus vials at $6.49 per vial. The price per vial is automatically applied at checkout based on quantity. A frequent issue is ordering just under a free‑shipping threshold, which adds $15.99 to the total; researchers can avoid this by rounding up to the next tier or consolidating orders to stay above $250.
