Sanitize
Wipe each vial stopper and the BAC water vial with an alcohol swab; let dry.
2
Draw diluent
Draw your target volume of bacteriostatic water into a sterile syringe.
3
Reconstitute
Inject the water slowly down the vial wall — never directly onto the powder. Swirl gently; do not shake.
4
Store
Refrigerate reconstituted vials at 2–8°C and log lot, date, and concentration.
