About * ADD ON ONLY * Hospira 30ML BAC Water
Hospira Bacteriostatic Water for Injection is a highly purified, sterile solution engineered for the reconstitution and preservation of lyophilized research compounds. This 30ML multiple-dose vial contains 0.9% (9 mg/mL) benzyl alcohol, which serves as a potent bacteriostatic agent. In laboratory research, it is the standard reagent for maintaining the sterility of reconstituted peptides, as the preservative inhibits the growth of microorganisms that could be introduced during repeated sampling. Hospira’s rigorous manufacturing ensures a non-pyrogenic and pH-balanced solvent, making it essential for high-accuracy in-vitro and in-vivo experimental models that require prolonged compound stability.
Mechanism of Action
The mechanism of action centers on the 0.9% Benzyl Alcohol concentration. It works as a bacteriostatic agent by disrupting the cell membranes of bacteria and denaturing essential proteins, thereby arresting the replication and growth of microorganisms. As a solvent, the distilled water provides a neutral aqueous medium for the solvation of proteins, while the preservative ensures that the solution remains safe for repeated entries for up to 28 days after the initial seal is broken.
