Bacteriostatic Water Canada — product reference
Bac water is the common short name for bacteriostatic water. Hermetica Research Labs lists Bacteriostatic Water 10ml as a Research Use Only laboratory reagent for Canadian laboratories. Composition is sterile water with 0.9% benzyl alcohol. Because it is a solution rather than a single compound, no CAS number is assigned and chromatographic purity does not apply.
No third-party certificate of analysis is published for this item. That is deliberate: Hermetica publishes lot certificates for the peptide lines that have them and does not publish one for this solution. Handling and storage follow the receiving laboratory's own protocol.
Orders ship within Canada only, flat $15 CAD per order and free on orders of $150 CAD or more, typically arriving in 5–12 business days in discreet packaging. Research Use Only — not for human or veterinary use. Purchasers must be 21+.

Component reference
The bac water label names two components. Their standard chemical identifiers are listed here so a laboratory record can reference them; they describe the components and are not a certificate for this vial.
| Component | CAS number | Formula | Molar mass | Role |
|---|---|---|---|---|
| Water | 7732-18-5 | H2O | 18.02 g/mol | Bulk of the solution, labelled sterile |
| Benzyl alcohol | 100-51-6 | C7H8O | 108.14 g/mol | Bacteriostatic preservative at 0.9% |
What the bac water label tells you, and what it does not
The label states what the solution is: sterile water with 0.9% benzyl alcohol in a 10ml vial, together with a lot number and a printed expiry date. "Bacteriostatic" means the preservative inhibits bacterial growth; it does not mean the solution sterilises anything it is combined with.
The label does not state compatibility with any particular peptide or material, and Hermetica does not publish preparation or in-use instructions. Any laboratory handling beyond storage of the sealed vial follows the receiving laboratory's own validated protocols and safety procedures.
Why no certificate of analysis is published for bac water
Certificates on this site are lot-level HPLC and mass-spectrometry reports for peptides. Those analyses measure the purity and identity of a single compound, so they do not apply to a solution of water and a preservative. No third-party certificate is published for Bac Water 10ml, and no certificate from another product or lot is substituted. The peptide certificates that do exist are listed on the Lab Results page, each tied to its own lot and testing laboratory.
Why bac water has no CAS number
A CAS registry number identifies one defined substance. Bac water is a solution of two substances, so the solution itself has no CAS number; each component has its own, as shown in the component reference table. Product pages that show a CAS number for bacteriostatic water as a whole are usually showing the number for water or for benzyl alcohol.
Receiving bac water into a laboratory inventory
- Inspect the outer package, the vial cap and the seal before signing the vial into inventory; photograph any damage.
- Confirm the label name (bacteriostatic water), the composition line and the 10ml volume.
- Record the lot number, the printed expiry date, the receipt date and who received it.
- Store the sealed vial as its label directs, in its original labelled container.
- Retire the vial from inventory at the printed expiry date.
Expiry date and storage
The expiry date printed on the vial label is the reference date for the laboratory record. Hermetica does not publish a separate in-use period for bac water. Storage follows the instructions on the vial label and the receiving laboratory's own protocol; keep the sealed vial in its original labelled container so the lot number and expiry date stay with it. General storage notes for the catalogue are in the research library's storage and handling guide.
What to keep in a purchasing record
- The product page as it read on the order date, with the price, SKU HRL-159 and the composition line.
- The order confirmation and the packing slip.
- The receiving entry: date, package and seal condition, lot number and printed expiry date.
- The storage location and the date the vial was retired from inventory.
