Reconstitution
Bacteriostatic Water (0.9% Benzyl Alcohol) is a sterile water solution used for the reconstitution of lyophilized research peptides. The 0.9% benzyl alcohol preservative prevents bacterial growth, allowing multi-use vial stability.
What is Bacteriostatic Water?
Bacteriostatic Water (0.9% Benzyl Alcohol) is a sterile water solution used for the reconstitution of lyophilized research peptides. The 0.9% benzyl alcohol preservative prevents bacterial growth, allowing multi-use vial stability. Available in 10mL and 3mL multi-use vials. For research use only. Not for human consumption.
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, a preservative that inhibits bacterial growth. That makes it suitable as a diluent for multi-draw laboratory vials. Genetic Peptides USA supplies it in 10mL vials as a laboratory reconstitution solvent.
Research peptides are shipped lyophilized (freeze-dried) for stability, and they have to be reconstituted into solution before they can be used in assays. Bacteriostatic water is one of the most common solvents for this step. Because of the benzyl alcohol, a reconstituted vial can be accessed more than once under lab conditions.
Always follow your institution's protocols and the compound's own solubility data.
Bacteriostatic water is not the right diluent for every compound. Some hydrophobic peptides need a small amount of dilute acetic acid or DMSO before aqueous dilution, and some cell-culture protocols require preservative-free sterile water because benzyl alcohol can affect sensitive assays. Always check each compound's solubility data and your protocol before choosing a solvent.
Store unopened vials at controlled room temperature away from light. Once punctured, follow standard lab practice for multi-use diluents.
Mark each reconstituted research vial with the compound, concentration, solvent lot and date. Tracking the bacteriostatic water lot alongside the peptide lot makes troubleshooting much simpler if an assay result looks unusual.
Is bacteriostatic water the same as sterile water? No. Sterile water has no preservative and is meant for single use. Bacteriostatic water contains 0.9% benzyl alcohol for multi-use research vials.
Does it ship from the USA? Yes. Genetic Peptides USA ships all orders domestically.
