Description
Set of calibration powders for pH meter
The kit consists of 3 calibration solutions for the pH meter:1. pH 4.00
2. pH 6.86
3. pH 9.18
Preparation of the calibration solution: dissolve one sachet of powder in 250 ml of distilled (deionized) water with a temperature of 25 ° C in a clean glass container. Only 20 ml of the solution is sufficient for one calibration.
It is necessary to store ready buffer calibration solutions in a dark, cool place (not in the refrigerator and at a temperature no higher than 25 °C) away from direct sunlight to prevent photochemical degradation. In addition, buffer calibration solutions must be protected from carbon dioxide ingress and stored in a tightly closed package.
Weight: 2 grams (for the preparation of 250 ml of solution)
Accuracy: ±0.01pH
