Official Peptides supplies USP-grade Bacteriostatic Water specifically formulated for reconstituting lyophilized research peptides. Each vial is sterile-filtered and preserved with 0.9% benzyl alcohol for multi-use stability. We ship from the US with reliable fulfillment and include Bacteriostatic Water as a core research supply item to complement your peptide orders.
Bacteriostatic Water for Injection (BWI) is sterile water preserved with 0.9% benzyl alcohol, which inhibits bacterial growth and allows a single vial to be used for multiple reconstitutions without contamination risk. It is the standard reconstitution vehicle for lyophilized peptides in research settings. The benzyl alcohol preservative maintains sterility for up to 28 days after first puncture when stored correctly. It is not intended for single large-volume injections or neonatal use. For research use only.
Q: Why use Bacteriostatic Water instead of sterile water for peptide reconstitution?
A: Bacteriostatic Water contains 0.9% benzyl alcohol, which prevents microbial growth and allows the vial to be accessed multiple times over 28 days while maintaining sterility. Sterile water for injection is a single-use product with no preservative and should be discarded immediately after opening. For research protocols requiring multiple reconstitutions from one vial, Bacteriostatic Water is the preferred choice.
Q: Can all peptides be reconstituted with Bacteriostatic Water?
A: Most lyophilized peptides dissolve readily in Bacteriostatic Water. A few peptides, such as IGF-1 LR3, require an acidic reconstitution vehicle (e.g., 0.1M acetic acid) for complete solubility. Check individual peptide solubility profiles before reconstituting, and refer to your laboratory protocol for guidance.
Q: How long does Bacteriostatic Water remain sterile after first use?
A: When accessed with a sterile needle and stored at room temperature away from light, Bacteriostatic Water remains stable and bacteriostatic for up to 28 days after first puncture. After 28 days, discard the vial regardless of remaining volume.
