Buffer capsules for 100 ml buffer solution
1.
Fill a plastic bottle with approx. 100 ml of distilled water.
2.
Open the buffer capsule carefully by twisting the capsule halves and pulling. It
should be ensured that nothing is spilled. They can also be used without opening
them; opening the capsules only reduces to time for dissolving.
3.
Place the buffer capsule and its contents in the plastic bottle.
4.
Wait at least 3 hours.
5.
Shake well before using for the first time.
Then you can begin with calibration of the product.
