RELT-200 Flow-injection electrochemiluminescence analysis instrument

RELT—200 flow-injection magnetic separation 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.

This instrument can separate the magnetic labeled antibody-antigen luminescent complex or the magnetic labeled gene hybridization luminescent complex, making them attached to the electrode and improving the detecting sensitivity.

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.
