- 2 Using a sterile syringe, draw the desired volume of bacteriostatic water (BAC water).
- 3 Insert the needle into the vial at an angle and slowly dispense the water down the inside wall — do not spray directly onto the powder.
- 4 Gently swirl (do not shake) the vial until the powder is fully dissolved.
- 5 Label the vial with the reconstitution date and concentration.
