pH Calibration down to minus 10 °C and Lower

Special buffer solutions and electrolytes for pH measurement at temperatures below 0 °C (< +32 °F). We manufacture these solutions specifically and particularly for pharmaceutical companies. Ask us for detailed information.

These electrolyte and buffer solutions are usually not in stock but are produced on request. Therefore, other compositions or other bottle volumes up to 20 L are possible. Other specifications possible on request.
