Research brief · Supplies
Bacteriostatic Water
Sterile liquid diluent (0.9% benzyl alcohol) — 10 ml × 10 vials.
Class
Reconstitution diluent
Half-life
N/A — solvent
Studied in
Standard reconstitution diluent for lyophilised research peptides.
What it is
Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol. It is the default diluent for reconstituting lyophilised research peptides where multi-day vial use is anticipated. Supplied as a sterile liquid — 10 ml per vial, 10 vials per kit (100 ml total). It is not a powder.
Mechanism studied
Sterile water preserved with 0.9% benzyl alcohol to inhibit microbial growth across multi-vial research use.
Research notes
- Supplied as a sterile liquid: 10 ml per vial, 10 vials per kit. It is not a powder.
- Once reconstituted, vials are typically stored refrigerated for the protocol's stability window.
- Use acetic acid instead for hydrophobic peptides that will not fully dissolve.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
