Liquid cell holder

25nm high quality SiNx membrane is used to seal liquid inside the TEM. Thickness of spacing layer ranges from 0 to 1um. 2, 3 or 4 electrodes are avilable for electrochemical measurement.

 

Application example

Electron induced growth of Ag partical in AnNo3 solution.

Gassing cell holder

Gassing cell holder enable the high temperature(800) and high gas pressure(1.2Bar) condition inside TEM. It could be used to study the catalysitic reaction, gas evironmental redox, material gowth and etching. Such system make your TEM to become a nano lab.
