Where to buy bac water in Canada

  • Bac water 10ml (Bacteriostatic Water 10ml) — one 10ml vial, SKU HRL-159, $8.00 CAD

The current CAD price is shown on the product page and in the catalogue card further down this page. One volume is listed: 10ml. Other vial sizes are not sold. It can be added to any order from the shop, alongside the lines on buy peptides Canada.

Bacteriostatic water 10ml specification

Field Value
Volume 10ml per vial
Composition (as labelled) Sterile water with 0.9% benzyl alcohol
Preservative Benzyl alcohol, 0.9%
CAS number Not applicable — a solution, not a single compound
Chromatographic purity Not applicable
Third-party certificate Not published (see below)
Listed storage Per label and laboratory protocol
SKU HRL-159

Bac water component reference

The label lists two components. Their standard chemical identifiers are below; they describe the components, not a certificate for this product.

Component Role on the label CAS number Formula Molar mass
Water Sterile water (the bulk of the solution) 7732-18-5 H2O 18.02 g/mol
Benzyl alcohol Bacteriostatic preservative, 0.9% 100-51-6 C7H8O 108.14 g/mol

A 0.9% benzyl alcohol content is commonly expressed as 9 mg per mL, which works out to roughly 90 mg of benzyl alcohol across a 10ml vial. The vial label is the reference for the exact statement on the product in hand.

What is in bacteriostatic water?

As labelled, bacteriostatic water is sterile water with 0.9% benzyl alcohol. The benzyl alcohol is the bacteriostatic preservative, and it is what separates bacteriostatic water from plain sterile water. "Reconstitution solution" is a general description rather than a fixed composition, so the label is the reference for what a given vial contains.

Bac water for peptides: what the label covers

Bac water is often ordered alongside lyophilized research peptides, and both can be added to the same order from the shop. The bac water label states composition only: sterile water with 0.9% benzyl alcohol, in a 10ml vial. It does not state compatibility with any particular peptide, and Hermetica does not provide preparation instructions. Any laboratory handling follows the receiving laboratory's own validated protocols.

Bacteriostatic water vs sterile water

The difference is on the label. Bacteriostatic water is labelled as sterile water with 0.9% benzyl alcohol. Sterile water is labelled as water with no bacteriostatic preservative listed. Hermetica lists bacteriostatic water only and does not sell sterile water. The full comparison is in bacteriostatic water vs sterile water.

Bac water compared with other laboratory waters

Bacteriostatic water (bac water) Sterile water Purified laboratory water (for example, Type I)
Composition as labelled Sterile water with 0.9% benzyl alcohol Water, no preservative listed Water, no preservative
Preservative Benzyl alcohol None None
Typical container labelling Multiple-use container Single-use container Bulk laboratory supply, often produced on site
What the grade describes Sterility plus a preservative Sterility Ionic and organic purity, for example resistivity of 18.2 MΩ·cm for Type I water
Listed by Hermetica Yes — Bac Water 10ml No No

The three are not interchangeable labels: each describes a different property. The labelling detail for the first two is in bacteriostatic water vs sterile water.

Why no certificate of analysis is published

Bacteriostatic water is a solution rather than a single compound, so 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, listed in the Certificates of Analysis library, and does not publish one here.

On receipt, record the reagent name, SKU HRL-159, the 10ml volume, the lot number, the printed expiry date and the seal and closure condition.

Expiry and storage

Use the expiry date printed on the label as the reference date for the laboratory record. Hermetica does not publish a separate in-use period. Storage follows the label and the receiving laboratory's own protocol; general notes are in research peptide storage and handling.

Receiving checklist for bac water

  1. Check the outer package and the vial cap and seal before signing the item into inventory.
  2. Confirm the label reads bacteriostatic water, with sterile water and 0.9% benzyl alcohol in the composition line, and a 10ml volume.
  3. Record the lot number and the printed expiry date.
  4. Store the vial as its label directs and keep it in its original labelled container.
  5. Retire the vial from inventory at the printed expiry date.

More questions about bac water in Canada

Is bac water the same as bacteriostatic water?

Yes. "Bac water" is the common short name. The label and our catalogue use the full name, Bacteriostatic Water.

Which sizes do you sell?

One size: a 10ml vial, SKU HRL-159. Larger vials are not listed.

Can I order bac water on its own?

Yes. It can be ordered alone or with other catalogue items; shipping is a flat $15 CAD per order and free on orders of $150 CAD or more.

Why is there no CAS number for bac water?

A CAS number identifies a single substance. Bac water is a solution of two substances, so the solution has none; its components, water and benzyl alcohol, each have their own CAS numbers, listed above.

Is a certificate of analysis available?

No. A peptide-purity certificate does not apply to this reagent, and none is published. Certificates for the peptide lines are in the COA library.

Does bac water ship cold?

No cold-chain packaging is used for any order. Store the vial as its label directs on receipt.

Do you sell sterile water?

No. Only bacteriostatic water is listed.

Research Use Only scope

Bacteriostatic water is supplied only as a laboratory reagent. It is not for human or veterinary use, and buyers must be 21 or older.
