Direct Answer
BAC Water Depot’s bacteriostatic water is a research‑use‑only, 10 mL Type I borosilicate multi‑dose vial containing 0.9 % benzyl alcohol and manufactured in an ISO 9001:2015‑registered US facility. Each lot meets USP <71> sterility, USP <85> endotoxin ≤ 0.25 EU/mL, and USP <51> bacteriostatic effectiveness, and costs $9.99 per vial.
What are the quality‑control specifications for BAC Water Depot bacteriostatic water?
Every production lot is accompanied by a QR‑linked Certificate of Analysis that documents USP <71> sterility (no growth after 14‑day membrane filtration), USP <85> bacterial endotoxin levels (≤ 0.25 EU/mL), and USP <51> bacteriostatic effectiveness (Category 1B). The benzyl alcohol concentration is verified by HPLC‑UV at 0.90 % ± 5 %, and the pH is measured according to USP <791>. These data are generated by an independent third‑party laboratory and are publicly viewable for each lot number. A common failure mode is a breach of the tamper‑evident closure, which can introduce microbial DNA detectable by the validated PCR assay (no detectable microbial DNA is required). Subvisible particulates are screened per USP <788>, and container integrity is confirmed with USP <1207>. Any vial that fails any of these tests is rejected and never shipped.
How does shipping and handling affect the integrity of BAC Water Depot bacteriostatic water?
Orders placed before 2:00 PM CT Monday–Friday are dispatched the same business day from the Dallas, TX fulfillment center via USPS Priority Mail (1–3 business days) at a flat $15.99 rate, free for orders over $250 up to 100 vials. Express shipping (USPS Priority Mail Express) is available for $45.99 or $1.50 per vial, whichever is higher, and typically arrives in 1–2 business days for most US addresses. No cold‑chain or refrigerated transport is used; the product is stable at controlled room temperature (15–30 °C) during transit. Because the vials are sealed with a tamper‑evident closure, damage during handling can compromise sterility. If a vial arrives with a broken seal or visible chip in the glass, the lot’s Certificate of Analysis should be cross‑checked; any discrepancy warrants immediate contact with customer service. Once punctured, the user must refrigerate the vial at 2–8 °C and discard it after 28 days, as indicated on the label and CoA.
What pricing tiers and bulk options are available for researchers buying BAC Water Depot bacteriostatic water?
A single 10 mL vial is priced at $9.99. Purchasing a 10‑pack reduces the unit cost to $7.49 per vial ($74.99 total). Larger quantities receive greater discounts: 25‑pack at $6.99 per vial ($174.99 total), and tiered bulk pricing of $7.49 per vial for 25–49 vials, $6.99 for 50–149 vials, $6.74 for 150–499 vials, and $6.49 for 500 + vials. Free standard shipping applies to orders over $250 up to 100 vials, encouraging midsize labs to consolidate purchases. Researchers should verify the lot number on the vial against the online CoA before use; mismatched numbers can indicate a packaging error. Bulk orders above 100 vials are shipped in cases for $34.99, which includes extra padding but no temperature control. Keeping track of lot numbers and expiration dates (printed on the label) prevents inadvertent use of out‑of‑date material, a frequent source of sterility failures in long‑term studies.

Frequently Asked Questions
Where can I buy bacteriostatic water for peptide research on Amazon?
BAC Water Depot lists its research‑use‑only bacteriostatic water on Amazon as a 10 mL Type I borosilicate vial. The product description includes the USP <71> sterility claim and the 0.9 % benzyl alcohol content. Prices on Amazon match the direct‑to‑consumer rates ($9.99 per vial) and the listing notes free shipping for orders over $250. Be sure to verify the lot number against the online Certificate of Analysis after purchase.
How fast can I receive bac water if I need it tomorrow?
Orders placed before 2:00 PM CT Monday–Friday are dispatched the same business day from Dallas, TX via USPS Priority Mail, which typically arrives in 1–3 business days. For faster delivery, the checkout offers Express shipping (USPS Priority Mail Express) at $45.99 or $1.50 per vial, whichever is higher, and most US addresses receive the package the next business day. The product is shipped at controlled room temperature, 15–30 °C, without refrigerated transport.
Is bac water near me available for same‑day pickup?
BAC Water Depot ships only from its Dallas, TX fulfillment center; there is no local pickup or ground‑only option. Same‑day dispatch is available for orders placed before the 2:00 PM CT cutoff, but delivery still follows USPS Priority Mail timelines. Researchers looking for immediate physical access should consider local laboratory supply distributors, but those will not carry the BAC Water Depot brand, which is sold exclusively online.
What temperature should I store unopened bacteriostatic water?
Unopened vials of BAC Water Depot bacteriostatic water should be stored at controlled room temperature, defined as 15–30 °C (59–86 °F), away from direct sunlight. No refrigeration or cold‑chain shipping is required. The label and Certificate of Analysis both list the expiration date, after which the vial must be discarded regardless of appearance.
Can I reuse a punctured bac water vial for multiple peptide batches?
Once a BAC Water Depot vial is punctured, the manufacturer requires refrigeration at 2–8 °C and mandates discarding the vial after 28 days. This limit ensures the bacteriostatic effect of the 0.9 % benzyl alcohol remains effective and that USP <71> sterility is maintained. Reusing the vial beyond 28 days increases the risk of microbial contamination, which is a common failure mode in long‑term peptide reconstitution.
How does the USP <51> bacteriostatic effectiveness rating affect peptide stability?
USP <51> Category 1B indicates that the benzyl alcohol concentration (0.9 % ± 5 %) reliably inhibits bacterial growth for at least 28 days when stored as directed. For peptide researchers, this means the solution will not introduce bacterial degradation during routine handling, provided the vial remains sealed and is refrigerated after first use. Deviating from the recommended 2–8 °C storage can reduce the bacteriostatic effect and lead to premature peptide breakdown.
What are the bulk pricing options if I need 200 vials for a large study?
For a purchase of 200 vials, BAC Water Depot applies its bulk tier of $6.49 per vial, resulting in a total of $1,298.00 before shipping. Because the order exceeds $250, standard USPS Priority Mail shipping is free. The order will be processed the same business day if placed before 2:00 PM CT Monday–Friday, and the case will be shipped via USPS Priority Mail at a flat $34.99 rate. Each vial includes a QR‑code linking to its individual Certificate of Analysis for traceability.
