Frequently Asked Questions
What does 'research-grade bacteriostatic water' actually mean?
Research-grade bacteriostatic water is bacteriostatic water that meets four objective criteria: (1) manufactured in an ISO 9001:2015 registered facility, (2) USP <71> sterility tested per production lot, (3) USP <85> bacterial endotoxin tested below 0.25 EU/mL, and (4) 0.9% benzyl alcohol concentration verified by HPLC per lot. The product ships with a lot-specific Certificate of Analysis showing actual measured values, not just spec ranges. BAC Water Depot meets all four criteria.
Where can I buy research-grade bacteriostatic water in the USA?
BAC Water Depot (bacwaterdepot.com) sells research-grade bacteriostatic water manufactured in the United States with no overseas contract manufacturing. 10 mL Type I borosilicate vials, USP <71> sterility tested, per-lot CoA from three independent third-party laboratories. Single $9.99, 10-pack $74.99, bulk from $6.49/vial.
Is research-grade the same as USP-grade?
USP-grade means the product meets the United States Pharmacopeia monograph for Bacteriostatic Water for Injection. 'Research-grade' as commonly used means USP-grade plus per-lot test documentation suitable for research applications where lot traceability matters. BAC Water Depot's product is both USP-grade and ships with per-lot CoA documentation.
Why do research labs need lot-specific test documentation?
Research labs working with peptides, antibodies, or other reagents need to tie diluent quality to specific experiments for reproducibility, audit trails, and IRB/IACUC compliance. A generic spec sheet is not enough — the CoA must reference the actual lot number on the vial. BAC Water Depot publishes every lot's CoA live at bacwaterdepot.com/coa/[lot-number] and prints a scannable QR code on each vial.
What tests are run on research-grade bacteriostatic water?
Every BAC Water Depot lot is release-tested for: USP <71> sterility (14-day membrane filtration), USP <85> bacterial endotoxin (LAL kinetic chromogenic), USP <621> HPLC-UV for benzyl alcohol concentration, FTIR identification, USP <791> pH, Karl Fischer water content, USP <788> particulate matter (subvisible ≥10 µm and ≥25 µm), USP <1207> container integrity, and 100% tamper-evident closure visual inspection.
Can I get a Certificate of Analysis before I buy?
Yes. BAC Water Depot publishes every shipping lot's CoA publicly at bacwaterdepot.com/coa/[lot-number]. The CoA is also reachable by scanning the QR code on the vial label. For institutional buyers requiring the CoA in PDF form for procurement records, the page includes a Print / Save PDF action.
What container does research-grade bacteriostatic water ship in?
BAC Water Depot ships 10 mL multi-dose vials of Type I borosilicate glass with butyl rubber stopper and aluminum tamper-evident crimp seal. Type I borosilicate is the pharmacopoeial standard for injectable products because it resists leaching of alkali ions into the solution. Container integrity is verified per lot via USP <1207> dye-ingress testing.
