Description

This pH buffer is used to calibrate pH combination electrodes.

To ensure exact calibration, buffer solutions must be handled carefully. All dirt is to be avoided. Therefore, never pour buffer solutions back into the storage bottle or calibrate directly in the storage bottle. Used buffer solutions are disposed of and not used a second time.

In the case of alkaline buffer solutions (pH > 7), the CO2 in the air causes a gradual neutralisation of the buffer. The storage bottles should therefore be resealed as soon as possible after use and contact with air reduced to a minimum.
