BACTERIOSTATIC WATERBAC WATER
Sterile water with 0.9% benzyl alcohol — multi-use diluent for reconstituting lyophilized material.
For laboratory research use only. Not for human or veterinary consumption, diagnostic or therapeutic use. Handle in accordance with institutional safety procedures.
Product Overview
Scientific profile
BACTERIOSTATIC WATER is sterile, non-pyrogenic water containing 0.9% (9 mg/mL) benzyl alcohol as a bacteriostatic preservative. The preservative inhibits the growth of most potentially contaminating bacteria, allowing the vial to be entered multiple times under aseptic technique.
Laboratory Use
It is used as a diluent for reconstituting lyophilized peptides and other research materials. Reconstitution should follow the requirements of the specific experimental protocol, adding the diluent slowly down the inside wall of the vial and swirling gently rather than shaking to avoid foaming and shear.
Handling Notes
- Use aseptic technique and swab the septum with 70% isopropyl alcohol before each puncture
- Discard 28 days after first puncture
- Store at controlled room temperature; do not freeze
- Benzyl alcohol may be incompatible with certain sensitive biologics — verify compatibility for your application
