Bacteriostatic Water

What It Is

Sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. Bacteriostatic water is the standard reconstitution solvent for lyophilized (freeze-dried) peptides in research settings. The benzyl alcohol prevents bacterial growth, allowing the reconstituted solution to be used over multiple research sessions without contamination.

How It Is Used

In peptide research, lyophilized compounds are dissolved by adding bacteriostatic water to the vial. The water is drawn into a syringe and injected slowly along the inner wall of the peptide vial, allowing the powder to dissolve without agitation. Once reconstituted, the peptide solution is typically stored refrigerated (2-8°C) and remains stable for multiple uses due to the bacteriostatic preservative.

USP-grade sterile water

Multi-use vial with sealed stopper

Store refrigerated after opening (2-8°C)

Essential Research Accessory

Bacteriostatic water is required for reconstituting all lyophilized peptides sold by 33 Degrees. Unlike sterile water (which contains no preservative and must be used in a single session), bacteriostatic water allows repeated withdrawals from a reconstituted peptide vial while maintaining sterility. It is recommended to have at least one vial of bacteriostatic water for every two to three peptide vials in a research protocol.

USP Grade Meets United States Pharmacopeia standards for purity
