Bacteriostatic water FAQs
8 questions
Storage & refrigeration
Does bacteriostatic water need to be refrigerated?
No. Store Quanta Nova BAC water at 20–25°C (68–77°F). Refrigeration is not required and does not extend the printed expiration date or the 28-day limit after first access. If you mix BAC water with another material, follow that material’s storage instructions; they may differ.
Shelf life & expiration
How long does bacteriostatic water last?
Unopened: Quanta Nova BAC water has a stated shelf life of two years from manufacture when stored as directed. Follow the printed expiration date.
After first access: After the first puncture, discard within 28 days or by the printed expiration date, whichever comes first. Record the first-access date; accessing the vial again does not restart the 28 days.
BAC water basics
What is bacteriostatic water?
Bacteriostatic water (BAC water) is water containing a preservative that inhibits bacterial growth. Quanta Nova BAC water contains 0.9% benzyl alcohol, is pH-balanced, and is micron-filtered to 0.2 µm. The preservative does not eliminate the need for careful handling.
What is the difference between bacteriostatic water and sterile water?
The main difference is the preservative. Quanta Nova BAC water contains 0.9% benzyl alcohol; Sterile Water for Injection contains no antimicrobial preservative. They are not automatically interchangeable. For laboratory research, follow the material’s instructions when choosing a solvent.
What is bacteriostatic water used for in laboratory research?
BAC water can be used as a diluent to dissolve or dilute compatible research materials. The correct solvent depends on the material and the research protocol. Follow the material’s instructions; BAC water is not suitable for every peptide or experiment. Quanta Nova BAC water is for laboratory research only.
Is reconstitution solution the same as bacteriostatic water?
Not necessarily. “Reconstitution solution” describes what a solution is used for, rather than a single formula. A product with that name may be BAC water or a different formulation. Check its ingredients, preservative concentration and the research material’s instructions before treating the solutions as interchangeable.
