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. 0401 = 0401 mercurous sulfate electrode (electrode rod diameter 6mm, suitable for inserting electrolytic cell cover hole with diameter of 6.1mm to 6.5mm).

2. 0402 = 0402 mercurous sulfate electrode (the difference between the above double salt bridge mercurous sulfate electrode and the single salt bridge mercurous sulfate 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 advisable to insert the electrolytic cell cover hole with a diameter of 10.1mm to 10.5mm).

3. 232=232 calomel electrode (the diameter of the electrode rod is 6mm, which is suitable for inserting into the electrolytic cell cover hole with a diameter of 6.1mm to 6.5mm).

4. 232-2 = 232-2 calomel electrode (the difference between the above double salt bridge calomel electrode and the single salt bridge calomel 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 advisable to insert the electrolytic cell cover hole with a diameter of 10.1mm to 10.5mm).

5. 0501=0501 single salt bridge mercury oxide electrode (electrode rod diameter is 6mm, suitable for inserting into the electrolytic cell cover hole with diameter of 6.1mm to 6.5mm).

6. 0502=0502 double salt bridge mercury oxide electrode (the difference between the above double salt bridge mercury oxide electrode and the single salt bridge mercury oxide 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 advisable to insert the electrolytic cell cover hole with a diameter of 10.1mm to 10.5mm).
