Application of "arm-and-hand system" in nucleic acid purification device

Lianhe Xing (Guangzhou Opto-mechatronics Research and development Centre, Guangdong 510635)  
Aiming at the current development of molecular biology, we designed the system which is used in distilling nucleic acid with the option of autocontrol and manual controll unit used for research of Molecular-Biology .The control unit based on the single-chip computer 89c58, consisted of A/D converter, LCD display, station switch, control key input, relay output controlled module, photoelec- tricity insulate module etc. The practical operation shows that the system can run well of steady state, excellent distill effect, high efficiency, better security and advinced automation.
