6213 glass shell double junction reference electrode
The 6213 double-junction reference electrode is suitable for use with various customized ion-selective electrodes.
Features:
1. Reference Solution: Both the first and second salt bridge solutions are user-selectable.
2. Junction: Ceramic
3. Unique double-junction structure reduces contamination. The measured solution can only contaminate the second salt bridge solution in the outer chamber, with minimal impact on the first salt bridge solution in the inner chamber. It also reduces liquid junction blockage and prevents ion exchange reactions between the first salt bridge solution and the measured solution.
4. Customizable Interface
