RELT-100 electrochemiluminescence detecting instrument can be used in the medical test of hormones, tumor markers, and antigens.

RELT—100 flow-injection electrochemiluminescence analysis instrument

   RELT—100 electrochemiluminescence detecting instrument can be used in the medical test of hormones, tumor markers, and infectious agents. It can also be used in the following fields: food safety, environment monitoring, life science and drug development, etc.

The sampling of this detecting instrument uses high-precision injection pump, which can precisely control the doses of the sample and the carrier fluid. It can mix the sample and the carrier fluid under any proportion and inject the mixture to the surface of the electrode at required speed.

This detecting instrument is integrated with multi testing interfaces, multi analysis parameters, and multi control parts. It can indicate and analyze chemiluminescence and electrochemiluminescence signals precisely.
