ABOUT THIS COMPOUND
Description

Bacteriostatic Water from Super Human Peptides UK is a highly purified, sterile solvent designed specifically for the reconstitution and dilution of lyophilized (freeze-dried) research peptides and proteins. In laboratory settings, proper reconstitution is critical to maintaining the structural integrity of delicate peptide chains. Unlike standard sterile water (which must be discarded immediately after a single use), Bacteriostatic Water is formulated with 0.

9% benzyl alcohol. This acts as a highly effective bacteriostatic preservative, halting the reproduction of most airborne and surface-level bacteria. When utilized in a sterile laboratory environment, it allows researchers to safely draw multiple doses from a single reconstituted vial over an extended period (typically up to 28 days) without risking microbial contamination or rapid peptide degradation.

Produced under rigorous GMP-compliant conditions, it is an absolute necessity for any facility conducting long-term peptide research.

WarningFor laboratory research use only. Not for human consumption.
Key Features
  • Preservative Action: Contains 0.9% Benzyl Alcohol to actively prevent bacterial and fungal growth.
  • Extended Vial Life: Allows reconstituted peptide solutions to remain sterile and viable for up to 28 days (when refrigerated).
  • Optimal pH: Chemically balanced to prevent the degradation or shearing of fragile peptide bonds during the mixing process.
  • Multi-Use Capability: Enables researchers to perform prolonged, multi-dose studies from a single reconstituted vial.
  • Quality Standard: GMP / ISO certified manufacturing ensuring absolute sterility.
NoteAll findings and protocols are derived from standard laboratory and non-clinical research settings.

Common questions
Frequently asked questions
It is a sterile solvent consisting of highly purified water with 0.9% benzyl alcohol by volume, supplied for reconstituting lyophilised research peptides. The benzyl alcohol acts as a bacteriostatic preservative.
It is the standard solvent for reconstituting lyophilised peptides, and is used in solubility studies, degradation prevention, volumetric dilution calculations and sterility monitoring across longer protocols.
Plain sterile water carries no preservative, so a punctured vial is effectively single use. The benzyl alcohol in BAC Water suppresses bacterial and fungal reproduction, supporting repeated draws from one vial for approximately 28 days when refrigerated.
Store unopened vials at room temperature. Once the stopper has been punctured, refrigerate at 2-8°C and treat the vial as having a working life of roughly 28 days.
Direct the solvent slowly down the inside wall of the peptide vial rather than onto the lyophilised pellet, then swirl gently and do not shake. Record the volume used so working concentrations can be calculated accurately.
It depends on the concentration the protocol requires; there is no fixed ratio. Choose a volume that gives a concentration convenient for your measurement method, and keep it consistent across runs so results stay comparable.
Yes. Sterility and composition documentation is available per batch, and each vial carries a batch number on the label. Quote that number and we will send the certificate matching the material you hold.
Purified water and 0.9% benzyl alcohol by volume, nothing else. It is manufactured under GMP/ISO certified conditions and its pH is controlled to avoid degrading peptides held in solution.
It ships from the UK to UK research addresses with tracked dispatch. It is supplied for in-vitro laboratory research only and is not a medicine, not a supplement, and not for human or veterinary use.
