Frequently Asked Questions
What is bacteriostatic water?
Sterile water preserved with 0.9% benzyl alcohol. It is the standard diluent for reconstituting lyophilized (freeze-dried) research compounds in laboratory settings. BacWater products are for research use only — not intended for human consumption.
How is it different from sterile water?
Plain sterile water contains no preservative and must be used within hours of opening. Bacteriostatic water's benzyl alcohol inhibits microbial growth, allowing multi-use over up to 28 days when stored correctly.
Are all sales final?
Yes. All sales are final. We do not accept returns, and a package returned to us is not reshipped. Refunds are considered case by case at our sole discretion and are never owed for carrier delays, returned packages or address errors. Please give a complete, correct address at checkout and respond if we contact you about your order.
Is each lot tested?
Yes. Every lot we publish has its own Certificate of Analysis, and the certificate states what was measured and who issued it. Batches of BacWater 10 mL are tested by an independent laboratory — neither us nor the supplier of the material; the other published certificates are issued in our own name. Certificates of analysis are published per lot on our Lab Results page.
How should I store it?
Room temperature, protected from light. Once opened, use within 28 days. Do not freeze.
Do you ship internationally?
We ship within the United States and to Canada. Free shipping on U.S. orders $125 and up. See our shipping policy for the full schedule.
What payment methods do you accept?
Major credit and debit cards via our secure checkout. Cryptocurrency accepted at a 5% discount.
How do I verify a lot?
Each product page links to the full lab-result history for that item. Every COA carries a lot number, test date, results, and the independent lab name. The COA URL is canonical — scan the QR on the label to verify.

What is Subscribe & Save?
Subscribe & Save is our auto-ship program. Choose a 45-day or 90-day cycle at checkout. Save 15% today and on every refill. Minimum 2 shipments — cancel before your 2nd and the 15% you saved is charged back to your card. Your card is charged automatically on the scheduled date and we ship the same items.
Can I pause, skip, or cancel my subscription?
Pause, skip or change your cycle anytime. Subscriptions have a minimum of 2 shipments: cancel before your 2nd shipment is charged and the 15% you saved on your first order is charged back to your card on file — you agree to this with a checkbox at checkout. After your 2nd shipment, cancel anytime. Every subscription email includes a one-click manage link. No phone call required.
When will I be charged?
Your first charge happens at checkout. After that, we charge the same card every 45 or 90 days (whichever you chose). You'll always get an email receipt before the next charge processes.
What happens if my card is declined?
We'll email you immediately and retry a few times over the next 9 days. If the charge still fails, we'll cancel the subscription automatically — no surprise charges, no collections.
Can I change what's in my subscription?
You can update the quantity from your manage link. To swap products, cancel the current subscription and start a new one at checkout with the items you want.
