Composition and specification.
Everything below describes what is in the vial and what the lot record says. We do not describe what it is for.
A 10 mL sealed glass vial of sterile water with 0.9% benzyl alcohol as the bacteriostatic agent — the benzyl alcohol is what makes the water bacteriostatic rather than plain sterile water.
It is the larger of the two volumes we carry, and it is the one most people order twice.
The lot shipping now is BAC10-D04. Genesis Bio Labs confirmed identity by FTIR, returned Sterile with a measured endotoxin value of 0.07 EU/vial on 9/26/2026, and issued document #9134065 on 10/12/2026. Enter the batch code and the card reads Verified · Pass.
The 10 mL and the 3 mL are the same specification. They are not the same lot, and they never share a certificate — a different fill run is a different lot, and a different lot gets its own testing. That is why the code on your vial matters more than the code on this page.
One product. Two volumes. Every lot documented before it ships.

Questions.
- 01Is the 10 mL the same water as the 3 mL?
- Same specification: sterile water with 0.9% benzyl alcohol as the bacteriostatic agent. Different fill volume, different lot, and a separate certificate for each. They are never tested as one lot.
- 02How do I verify my lot?
- Enter the batch code printed on the vial — for example BAC10-D04 — in the lookup on this site, or open the verify link for the lot. The card returns Verified · Pass with document #9134065, identity confirmed by FTIR, potency assay Sterile, endotoxin 0.07 EU/vial, tested 9/26/2026, issued 10/12/2026. Confirm the batch code, document ID and test date on screen match the vial in your hand. A code we did not issue returns No certificate found.
- 03Why publish endotoxin and sterility per lot instead of once?
- Because a certificate that covers 'our water' covers nothing you are holding. Testing per lot is the only version of this that can answer a question about a specific vial. Lot BAC10-D04 reads 0.07 EU/vial, Sterile, identity confirmed, tested 9/26/2026, document #9134065, signed off by two analysts at Genesis Bio Labs.
- 04What happened to older lots?
- They stay published. Prior 10 mL lots on file: BAC10-J15 and BAC10-260810. We do not remove a certificate when a lot sells through — a record you cannot go back and check is not a record.
- 05How is it packaged and shipped?
- Each vial ships sealed, with its flip cap intact, padded in a box rather than an envelope. Orders placed before 2:00 PM CT on a business day leave our facility the same day, and tracking is emailed as soon as the label is made.
- 06Can you tell me what to do with it?
- No. We do not advise on applications or answer questions about them. We sell laboratory water and publish its certificate. Research Use Only. Not for human or veterinary use.
