Reconstitution

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 1.0 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.

Storage conditions

Stored below -18°C unopened controls are stable until the expiry date which is stated on the vial labels. The reconstituted control can be stored up to one week light protected, tightly capped at +2 to +8 °C. If the controls cannot be analysed within this period, they should be aliquoted and stored frozen below -18 °C (up to 3 months).
