ALS RE-61V

Screw type Hg/HgO Reference Electrode  RE-61VT  for alkaline solution ALS 014052.

The RE-61VT reference electrode is made of Hg/HgO instead of calomel paste, and 1 M sodium hydroxide is used as an electrolyte solution. It has the specific design to be suitable for the ALS line-up flow cell:

Also, potassium hydroxide solution can be used as a internal solution, instead of sodium hydroxide solution.

HgO + H2O + 2e = Hg + 2OH-  ​E0=118 mV vs RHE (25 ºC)

Material: Polymethylpentene (high chemical resistance)

Junction: Ceramic tip

Diameter: 10 mm
