The mall is specialized in the production and sales of high-purity experimental products for "scientific research institutes, universities and other" scientific research institutions and laboratories. When purchasing high-purity industrial products for production in non low-cost factories, relatives should buy them according to their own actual use to avoid "claiming" that they can also enter the laboratory as experimental products and the same industrial production products, which will affect the accuracy and accuracy of experimental results.

1. R0301= silver chloride electrode, the electrode rod is made of polytetrafluoroethylene, and the diameter of the electrode rod is 8mm.

2. R0302= silver chloride electrode, electrode rod diameter is 3.8mm, connected with ceramic penetrant.

3. R0302-1= silver chloride electrode, electrode rod diameter is 4mm, PTFE permeable liquid connection.

4. R0303= silver chloride electrode, electrode rod diameter is 6mm, length is 60mm.

5. R0305= saturated silver chloride electrode, electrode rod diameter is 5.75mm, length is 50mm.

6. R0305-1= saturated silver chloride electrode, electrode rod diameter is 5.75mm, length is 75mm.

7. R0305-2= saturated silver chloride electrode, electrode rod diameter 6mm, length 65mm.

8. R0305-3 = R0305-3 double salt bridge saturated silver chloride electrode (the difference between the above double salt bridge saturated silver chloride electrode and the single salt bridge saturated silver chloride electrode is that there is a protective sleeve outside the lower electrode rod. The diameter of the protective sleeve is 10mm, and the diameter of the inner electrode rod is 6mm. After the protective sleeve is put on, it is best to insert an electrolytic cell cover hole with a diameter of 10.1mm to 10.5mm).
