Research Water 10mL 0.9% Benzyl Alcohol

Overview

Research Water 0.9% Benzyl Alcohol is a clear, colorless, non-pyrogenic solution of benzyl alcohol (0.9% w/v) in purified water, USP. Benzyl alcohol functions as an antimicrobial preservative, allowing repeated withdrawals from a single vial over the course of a study. It is supplied in a 10 mL multiple-withdrawal glass vial with a rubber stopper and aluminum crimp seal.

This solution is used as a general aqueous solvent and diluent for lyophilized peptides and other research compounds that require dissolution prior to in-vitro laboratory analysis.
