This product is temporarily out of stock online.
For making calibration solutions for pH meters. Consists of two capsules, orange for pH 4 and green for pH 7. Creates a consistent pH level for meter calibration.

Buffer solution preparation:
1. Remove the capsule from the packaging.
2. Empty the powder from the capsule into a container.
3. Add 100 ml distilled water.
4. Mix the powder until it is completely dissolved.
 
For precise measurements the instrument should be calibrated using a buffer solution before each use. Recalibration does not need to be done during use, provided that this period does not exceed 1-2 hours.
 
Prepared solutions are normally used only once and any remaining solution is typically disposed of. However, this solution can also be stored for up to a year if stored in a sterile container. Store chilled, preferably in a refrigerator.
