Description
Bacteriostatic water is sterile water with a small amount of benzyl alcohol added as a preservative. We supply it in a 10 mL multi-draw vial for reconstituting lyophilized research peptides.

|---|---|---|---|
| Water | 7732-18-5 | 18.015 g/mol Formula: H2O |
Component identity; the finished bacteriostatic-water product is a mixture and has no single CAS number or molecular weight. |

Preservative component. |
Bacteriostatic water is a formulated mixture; component identities are shown separately.
Storage: Store at controlled room temperature, 20–25°C, protected from excessive heat and freezing. Follow the supplied container and laboratory procedure for dating after first entry.
What bacteriostatic water is.
Standard bacteriostatic water contains 0.9% benzyl alcohol, which is 9 mg per mL. Bacteriostatic means the preservative holds back bacterial growth rather than killing every organism. That is what lets a vial be punctured and drawn from more than once. Confirm the exact composition of your lot on its label and COA.
Plain sterile water has no preservative. It is meant for single use and should be thrown away once opened. Some compounds react badly to benzyl alcohol, so check compatibility with your protocol.

How laboratories use it.
Peptides ship as dry powder because they keep far better that way. To prepare one, a researcher adds a measured volume of diluent to the vial. The resulting concentration is the peptide mass divided by the volume added: 10 mg in 2 mL gives 5 mg per mL.
Run the water slowly down the inside wall of the vial instead of straight onto the powder, then swirl gently rather than shaking. That avoids foaming and protects the peptide.
What it pairs with.
Every vial in our catalogue is lyophilized, including BPC-157, GLP-3, GHK-Cu, ipamorelin and sermorelin. Browse all peptide vials.
Documentation.
Available analytical documentation is organized by compound, strength and format in the COA library. Do not treat a report as lot-specific unless a documented lot match is shown.
Handling.
Keep the vial away from heat and direct light, and follow the storage conditions on its label. Once the stopper has been punctured, follow your laboratory’s protocol for how long it stays in use.
Questions.
What is bacteriostatic water for?
In research, it dissolves lyophilized peptides and other powders into a solution, which is called reconstitution.
Is it the same as sterile water?
No. The benzyl alcohol in bacteriostatic water lets you draw from the vial more than once. Sterile water has no preservative, so each vial is used once.
Do capsules or sprays need it?
No. Only the powder vials need mixing; capsules and sprays come ready.
