Sterile bacteriostatic water for injection (BWFI) containing 0.9% benzyl alcohol as a bacteriostatic preservative. 30ml multi-dose vial. USP grade. Essential supply for reconstituting lyophilized research peptides. For research use only.
Bacteriostatic water is sterile water for injection with 0.9% benzyl alcohol added as a bacteriostatic preservative. The benzyl alcohol allows the water to be reused multiple times without supporting bacterial growth between uses. Supplied here as a 30 ml USP-grade vial for laboratory research only.
Sterile water for injection contains no preservative and must be discarded after a single use. Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits bacterial growth and allows multiple draws from the same vial within the manufacturer-specified period (typically 28 days).
Reconstituting lyophilized research peptides for in-vitro experimental work. The benzyl alcohol preservative is compatible with most peptide chemistries; check peptide-specific compatibility data when working with sensitive sequences.
