Operating System

 

1. Operation system has 7.5 inches large color touch display screen, SIEMENS CPU control platform, and can be connected to wireless mouse.

2. It has Chinese display interface with perfect man-machine interaction function, and the operational process is easy to operate and understand.

3. Two operating modes, automatic analysis and manual analysis, can meet requirements of different experiments.

4. USB data communication interface, standard configuration, is convenient for users to inquire raw data.

5. Wireless mouse, standard configuration.

 

Executive system

It adopts self-priming diaphragm pump imported with original packing from British to feed liquid and thoroughly weeds out pneumatic diaphragm pump used by many domestic factories. Feeding liquid by self-priming pump can put liquid-feeding barrel under the operation floor which has advantages of effectively saving lab room, choosing large capacity liquid-feeding barrel, etc.
