Reconstitution

Carefully remove the rubber stopper from the vial (Caution when removing the metal seal: Risk of injuries due to sharp cutting edges!). Add exactly 5.0 ml of distilled water into the vial. Replace the stopper and allow to sit for 10 to 15 minutes at room temperature. Swirl the vial to dissolve the contents until homogeneity.

Storage conditions

Stored at +2 to +8 °C unopened calibration standards are stable until the expiry date which is stated on the vial labels.

The reconstituted calibration standard should be stored tightly capped at +2 to +8 °C. Generally the calibration standard can be stored for two days at +2 to +8 °C. If the calibration standard cannot be analysed within this period, it should be aliquoted and stored frozen below –18 °C (up to 3 months).
