Bac Water 10ml

Bacteriostatic Water is a crucial diluent in scientific research, particularly for preparing solutions of lyophilized peptides, proteins, and other research compounds for in vitro and in vivo studies. The inclusion of 0.9% benzyl alcohol acts as a bacteriostatic agent, inhibiting the growth of most contaminating bacteria within the solution. This preservative allows for multiple withdrawals from the same vial over an extended period, significantly reducing the risk of microbial contamination compared to sterile water without a preservative. Its sterile and non-pyrogenic nature ensures that it will not introduce unwanted biological contaminants or fever-inducing substances into sensitive experimental systems. For optimal research integrity and safety, proper handling of Bacteriostatic Water is paramount. Always use aseptic techniques when accessing the vial, including swabbing the rubber stopper with an alcohol wipe before each withdrawal. Use a sterile syringe and needle for reconstitution and dilution processes. Once a research compound is reconstituted, follow the specific storage guidelines for that compound, as the stability of the compound, not the bacteriostatic water itself, will dictate its shelf life. Store unopened vials of Bacteriostatic Water at controlled room temperature (20°C to 25°C, 68°F to 77°F). Protect from freezing and excessive heat. Once the vial has been entered (punctured), the bacteriostatic properties of benzyl alcohol typically allow for the solution to be used for up to 28 days, provided aseptic techniques are maintained. Always inspect the solution visually for particulate matter and discoloration prior to use. Discard any unused portion after 28 days or if contamination is suspected.
