White-Label Bacteriostatic Water: Unlabeled Vials for Resellers

What are the exact composition and sterility specifications for white-label bac water?

BAC Water Depot's bacteriostatic water is a sterile aqueous solution of USP-grade water containing 0.9 % (w/v) benzyl alcohol as a preservative. The water meets USP <71> sterility requirements, with each 10 mL vial undergoing a membrane filter test that must show <1 CFU per 100 mL. The solution is packaged in Type I borosilicate glass vials that are pre-sterilized by autoclave at 121 °C for 15 minutes, ensuring endotoxin levels below 0.05 EU/mL as verified by the third-party labs.

The sterility test is performed on every production lot by an independent laboratory; the lab issues a Certificate of Analysis that is linked via a scannable QR code on the vial. A common failure mode is a breach of the vial seal during transport, which can introduce microbial contamination and invalidate the USP <71> result. To avoid this, BAC Water Depot ships the vials in sealed, insulated cartons with a desiccant pack and advises users to inspect the vial for any glass cracks or seal imperfections before use.

How should unlabeled bacteriostatic water be stored and what is its shelf life?

Store unopened vials at 15–30 °C, away from direct light, and do not freeze. The expiration date is printed on each vial and on the lot's Certificate of Analysis; unlabeled vials carry the same lot and expiry on the outer case label. After first puncture, refrigerate at 2–8 °C and discard at 28 days — the standard in-use limit for a multi-dose bacteriostatic water vial, regardless of how much volume remains.

Resellers should keep the case-level lot label with the inventory until every vial from that case has shipped, so any customer question can be answered against the right CoA. Log the date of first opening on any vial you use in-house, and discard a vial that shows cloudiness, particulates, or a compromised stopper.

Who buys white-label bac water, and how does relabeling work?

The typical white-label buyer is a research peptide company or lab-supply reseller that wants to offer a diluent under its own brand without manufacturing one. Unlabeled vials are available on orders of 25 or more; you apply your own label, and the outer case keeps the BAC Water Depot batch/lot label so the per-lot Certificate of Analysis stays traceable to every vial you ship. Some resellers publish that CoA in their own documentation library under their brand.

The product inside is the same research-grade bacteriostatic water sold under the BAC Water Depot label: sterile water with 0.9% benzyl alcohol in a 10 mL Type I borosilicate vial, manufactured in an ISO 9001:2015-registered US facility and USP <71> sterility and USP <85> endotoxin tested per lot by an independent laboratory. Labeling content, claims, and research-use-only compliance for the relabeled product are the reseller's responsibility.
