About bacteriostatic water

Research applications

Standard diluent for reconstituting lyophilized peptides prior to experimental use in vitro or in preclinical models. Compatible with most synthetic peptides in the MX-1 Labs catalog.

Storage and handling

Store at controlled room temperature, protected from direct light. After the first septum puncture, refrigerate the vial at 2–8 °C and discard after 28 days or earlier if turbidity, suspended particles, or color change is observed.

Frequently asked questions

• Is this pharmaceutical-grade water for injection?+

  It is sterile water filtered through 0.2 µm with 0.9% benzyl alcohol as a preservative, intended for experimental reconstitution of lyophilized peptides in the laboratory. It is not a pharmaceutical product approved for human or veterinary administration.

• How long does the vial last once opened?+

  The 0.9% benzyl alcohol inhibits microbial growth once the septum is pierced. Refrigerate at 2–8 °C after first puncture and discard after 28 days or earlier if turbidity, particles, or color change is observed.

• Why is it used to reconstitute lyophilized peptides?+

  Because the preservative allows fractional use of the vial across multiple reconstitutions within the lab SOP stability window. Plain water without a preservative requires immediate use of the full volume.
