BACTERIOSTATIC WATER research vial by Regent Peptides

Research compound

Bacteriostatic Water

£10.00/ 3ml vial

Volume

Sterile water with 0.9% benzyl alcohol, for reconstitution

Bacteriostatic water is sterile, non-pyrogenic water containing 0.9% benzyl alcohol as a preservative, which inhibits bacterial growth in a multi-use vial. It is the standard laboratory diluent for reconstituting lyophilised peptides where a prepared solution will be drawn from more than once.

Supplied in 3 ml and 10 ml sealed vials. Store at room temperature, protected from light, and discard any vial showing particulates or cloudiness.

Use our reconstitution reference on each peptide page to calculate the resulting concentration for a given diluent volume. For laboratory use only.

Order before 3pm for same-day UK dispatch on Royal Mail Tracked 24, from £4.99.

Independent testing

All lab reports

HPLC and mass spectrometry on every batch. Certificate of Analysis available on request.

Third-party analysis by Janoshik Analytical. Each certificate is verifiable on the laboratory’s own site.

  • Manufactured and lyophilised in the UK
  • Plain, tracked packaging from £4.99
  • For laboratory research use only

Research Handling Guidance

Before reconstitution, allow both the lyophilised peptide and your chosen diluent to settle at normal laboratory room temperature. Equalising temperatures in this way supports the structural stability of the compound while it goes into solution.

Diluents and reconstitution solutions are purchased separately.

Bacteriostatic Water questions

Bacteriostatic water or sterile water?
Sterile water contains no preservative and is suited to single-use preparation. Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits bacterial growth and is preferred where a reconstituted vial will be stored and sampled repeatedly.
Is this for human use?
No. All Regent Peptides products are supplied strictly for in-vitro laboratory research. They are not medicines and are not for human or veterinary use, diagnosis or treatment.
