Pfizer Bacteriostatic Water for reconstitution
Bacteriostatic water is sterile water with 0.9% benzyl alcohol added as a preservative. The additive suppresses microbial growth between draws, which is what lets a single reconstituted vial be accessed repeatedly across a research period rather than only once. It is the standard diluent for dissolving lyophilized peptides and other freeze-dried reference compounds in the laboratory.
Why the 30 mL format
Supplied as a Pfizer 30 mL multi-dose vial — three times the volume of a standard 10 mL presentation. For work that reconstitutes many compounds or larger masses, the larger vial means fewer vials to open and track, and less packaging per millilitre of diluent.
Working out the volume
The volume of diluent sets the concentration of the resulting solution, so it is decided before the vial is opened. The reconstitution calculator finds the diluent volume for a target concentration, and the step-by-step guide covers technique. See also bacteriostatic vs. sterile water for when each is appropriate.
Storage and handling
Unopened vials are stored at room temperature away from direct light. Once a vial has been entered, note the date — the preservative extends the usable window but does not make it indefinite. Pair it with our sterile single-use syringes for measuring and transfer.
