Bacteriostatic Water Near Ne

What are the specifications of BAC Water Depot’s bacteriostatic water?

BAC Water Depot’s bacteriostatic water is manufactured in a US ISO 9001:2015‑registered facility and packaged in 10 mL Type I borosilicate multi‑dose vials. Each vial contains 0.9 % ± 5 % benzyl alcohol, verified by HPLC‑UV, and is tested for sterility per USP <71> (14‑day membrane filtration) with no microbial growth. The independent third‑party laboratory also performs bacterial endotoxin testing (USP <85>) with a limit of ≤ 0.25 EU/mL, and a validated PCR assay confirms no detectable microbial DNA, ensuring a clean, bacteriostatic environment for peptide handling.

The product’s USP <51> bacteriostatic effectiveness is classified as Category 1B, guaranteeing sustained inhibition of bacterial growth when stored correctly. Unopened vials must be kept at controlled room temperature 15–30 °C, out of direct sunlight, with no refrigeration or cold‑chain shipping required. Once punctured, the vial should be refrigerated at 2–8 °C and discarded after 28 days; the expiration date is printed on the label and the Certificate of Analysis. Each lot’s CoA is accessible via a QR code linking to bacwaterdepot.com/coa/<lot-number>.

How can I purchase bacteriostatic water quickly for my lab in the Northeast?

Orders placed before 2:00 PM CT Monday through Friday are processed the same business day from the Dallas, TX fulfillment center. Standard shipping uses USPS Priority Mail with a flat rate of $15.99 and typically arrives in 1–3 business days; orders over $250 (up to 100 vials) qualify for free standard shipping. For faster delivery, the Express option (USPS Priority Mail Express) costs $45.99 or $1.50 per vial, whichever is higher, and reaches most US addresses the next business day, though next‑day delivery cannot be guaranteed.

Bulk pricing reduces the per‑vial cost: a single vial is $9.99; a 10‑pack is $74.99 ($7.49 each); a 25‑pack is $174.99 ($6.99 each). Larger orders receive tiered discounts—$7.49 per vial for 25–49, $6.99 for 50–149, $6.74 for 150–499, and $6.49 for 500 + vials. All purchases are research‑use‑only, and the website provides a secure checkout with the option to upload a QR‑linked CoA for each lot, ensuring traceability for quality‑controlled experiments.

What are common issues when using bacteriostatic water for peptide reconstitution?

A frequent problem is microbial contamination after the vial is punctured; even though the product is USP <71> sterile, failure to refrigerate the opened vial at 2–8 °C can allow bacterial growth, rendering the water unsuitable after the 28‑day discard window. Users should also inspect the vial for subvisible particulates (USP <788>) before use; any visible particles may indicate container integrity failure (USP <1207>) and require discarding the vial to avoid assay interference.

Another issue arises from inaccurate benzyl alcohol concentration; deviations beyond the 0.90 % ± 5 % specification can affect peptide solubility and stability. Researchers should verify the pH (USP <791>) is within the expected range for their peptide, as extreme pH shifts can cause aggregation. If the QR‑linked CoA shows out‑of‑spec results for endotoxin (USP <85>) or microbial DNA, the batch must be rejected, and a new lot ordered to maintain experimental integrity.
