Carefully remove the metal seal and rubber stopper from the vials. (Caution when removing the metal seal: risk of injuries due to sharp cutting edges!). Add exactly 2.0 ml of distilled water into each vial. Return the stopper and incubate for 10 to 15 minutes at room temperature. Swirl the vials to dissolve the contents until homogeneity.
