Bipotentiostat model CS2350

Two sets of built-in independent potentiostat /galvanostat. Experiments can be conducted simultaneously in each channel. Besides this, the two channels can jointly complete experiment of two-working electrode system such as RRDE and HDT. CS2350 equals to two sets of single-channel potentiostat(CS350+CS150).

CS2350 bipotentiostat has two sets of built-in independent potentiostat /galvanostat. Experiments can be conducted simultaneously in each channel. Besides this, the two channels can jointly complete experiment of two-working electrode system such as RRDE and HDT. CS2350 bipotentiostat is the real double-channel potentiostat. It uses Ethernet connection. The customer can choose to use only one channel or both channels during experiment.CS2350 equals to two sets of single-channel potentiostat(CS350+CS150).

Application

(1) Electrosythesis, electrodeposition (electroplating), anodic oxidation, electrolysis
(2) Oxygen reduction reaction(ORR), oxygen evolution reaction (OER), Hydrogen evolution reaction(HER), carbon dioxide reduction.
(3) Energy and materials (Li-ion battery,solar cell, fuel cell, supercapacitor), advanced function materials, and sensor.
(4) Corrosion behavior of metals, and anti-corrosion evaluation
(5) Fast evaluation of inhibitor, water quality stabilizer, coating, and cathodic protection efficiency.


Typical applications for bipotentiostat

Rotating ring-disk electrode(RRDE)
Oxidation/reduction reaction (ORR) study: while measuring the polarization curve of disk electrode in the main channel, apply a constant polarization potential on the ring electrode, and thus detect the intermediate products on the disk electrode. RRDE test becomes the typical method for ORR study.

Hydrogen diffusion test(HDT)
Two-channel potentiostats are combined with H-cells. By measuring current of cathode hydrogen charging (the left cell) and hydrogen atoms anode oxidation (the right cell), it can further calculate the diffusion coefficient of hydrogen atoms in metal and hydrogen flux.
