Description

Bacteriostatic Water for Laboratory Research (0.9% Benzyl Alcohol)

Sterile laboratory reconstitution medium and solvent containing 0.9% benzyl alcohol for in vitro dissolution of lyophilized peptides, proteins, and biochemical reagents with microbial proliferation inhibition during multi-dose sampling

Overview & Functional Role in Laboratory Research (In Vitro)

Bacteriostatic Water is a highly purified, sterile, and non-pyrogenic laboratory solvent containing a precisely defined concentration of 0.9% (9 mg/mL) benzyl alcohol (), which acts as a bacteriostatic preservative. In analytical biochemistry, molecular biology, and peptide research, it serves as the standard reconstitution medium for lyophilized compounds requiring multiple aliquot withdrawals from a single stock vial:

  • Inhibition of Microbial Proliferation: Benzyl alcohol disrupts the membrane integrity of a broad spectrum of Gram-positive and Gram-negative bacteria as well as fungi, preventing microbial contamination and secondary degradation of sensitive peptide solutions upon repeated vial access.
  • Stabilization of Reconstituted Solutions: Provides a stable aqueous medium with a neutral to slightly acidic pH profile (pH 4.5–7.0), minimizing peptide bond hydrolysis and preserving stock solution stability when stored at 2–8 °C.
  • Broad Reagent Compatibility: Suitable for solubilizing most synthetic sequences, hydrophilic peptides, and bioregulators without compromising their secondary structure or interfering with analytical characterization (e.g., HPLC and Mass Spectrometry).
  • High Purity & Non-Pyrogenic Standard: Strictly deionized water free from organic impurities, heavy metal ions, and endotoxins, ensuring high reproducibility in in vitro assays and cellular cultures.
