Remarks
- Be careful not to contaminate this product with substances like antibiotics, other drugs, cleaning agents or disinfectants.
- Clean hands, bench etc. with soap and rinse extensively with tap water.
Preparation
- Tear off the aluminum seal of the bottle. Carefully remove the stopper from the bottle and place it upside down on the bench.
- Add 15 ml (± 0.5 ml) of distilled or demineralized water to the bottle with a clean pipette.
- Replace the stopper. Hold the stopper in place and gently mix the contents by inverting the bottle twenty times.
Avoid foaming. Make sure that a homogeneous solution is obtained. Otherwise proceed with the mixing till all particles are dispersed. Allow the contents to equilibrate at room temperature for 20 minutes and remix gently.
Storage
- Store bottles between 2 – 8°C.
- Keep reconstituted Controls at 2 – 8°C (or on ice) between uses, and use only on the day of reconstitution.
- Reconstituted Controls may be portioned out into small volumes and frozen for later use as follows:
Use clean vials of appropriate size. Label vials with the batch number and
date of preparation. Reconstitute as described above and without delay pipette
the required amount (e.g. 2 ml) into vials, close the vials tightly and place
vials directly in a freezer of -18°C. Use within 2 months.
On the day of use, thaw the sample by putting the closed vial for a short time
in lukewarm water and mix the contents. Thawed samples may be used on the same
day only, if kept at 2 – 8°C (or on ice).
