the switch of magnetic valve, the compression of centrifugal pipe close and unclamping and the switch of centrifugal lid.Centrifugal seat can be provided with the centrifugal tube seat of even number as required, during use, centrifuge tube and DNA adsorption column interval are put into centrifugal tube seat, and be described centrifugal seat to be arranged four centrifugal tube seats below, four centrifugal tube seats are numbered No. one to No. four in turn; There is positioning inductor on a centrifugal tube seat side, can automatically be parked on the position of No. after the sensor sensing corresponding on centrifugal work platform.When extracting plasmid, first, manually cleaning centrifuge tube and No. three centrifuge tubes are put into a centrifugal tube seat and No. three centrifugal tube seats respectively, No. two DNA adsorption columns and No. four DNA adsorption columns are put into No. two centrifugal tube seats and four No. three centrifugal tube seats respectively, and the inoculum (about 1.5mL) of the equal volume fermented is added in No. one and No. three centrifuge tubes, then the support of lifting gland rotary lifting mechanism is rotated, lifting gland is turned to the top of centrifugal seat from the side horizontal of centrifugal seat, move down lifting gland again, be pressed on four corresponding centrifuge tubes after four the centrifugal pipe closes be placed in advance below lifting gland are unclamped, then support moves and lifting gland is horizontally rotated to original position.Then, fasten centrifugal lid, Centrifugal vibration device is to the inoculum rotating centrifugal in No. one and No. three centrifuge tubes, centrifugal complete after, centrifugal lid is opened, lifting gland turns to above centrifugal seat from the side horizontal of centrifugal seat, move down again and four centrifugal pipe closes are unclamped simultaneously and is fixed on below lifting gland, buck covers moves, horizontally rotate support again to original position, at this moment bacterial precipitation is in the bottom of No. one and No. three centrifuge tube, the L bracket of liquid adding and extracting device is rotated subsequently, horizontally rotate above centrifugal seat by moving liquid dish, rotate again and move liquid dish and make the first waste liquid suction pipe turn to directly over a centrifuge tube, move down and move liquid dish, the disposable long plastics tubing loaded onto in advance by first waste liquid pipette tip slowly enters a centrifuge tube, supernatant fluid wherein is slowly blotted, then rotating moves above liquid dish to waste liquid tank, waste liquid is discharged in waste liquid tank, rotate again and move liquid dish and make the first waste liquid suction pipe turn to directly over No. three centrifuge tubes, move down and move liquid dish the long plastics tubing of the first waste liquid suction pipe lower end is slowly entered No. three centrifuge tubes, supernatant fluid wherein is also slowly blotted and is discharged in waste liquid tank.Then move liquid disc spins the first liquid adding bottle is moved to directly over a centrifuge tube and adds quantitative re-suspension liquid 250 μ l by solenoid control, then the re-suspension liquid of equal volume is added in No. three centrifuge tubes, by above-mentioned mode, centrifugal pipe close is pressed on centrifuge tube, start Centrifugal vibration device, centrifuge tube thermal agitation 1 minute, make microorganism even suspension, rotate again and move liquid dish and the second liquid adding bottle is moved to above a centrifuge tube and No. three centrifuge tubes respectively and the bacteria lysis solution 250 μ l being added new preparation by solenoid control, according to the above-mentioned method centrifuge tube that vibrates gently, solution is mixed by Centrifugal vibration device, finally rotate move liquid dish the 3rd liquid adding bottle is moved to above a centrifuge tube and No. three centrifuge tubes respectively and by solenoid control add ice-cold in and the neutralization solution 350 μ l of pH, by Centrifugal vibration device according to above-mentioned method vibrate gently centrifuge tube make solution mix after centrifugal.After centrifugal end, mobile and rotate and move the disposable long plastics tubing that liquid dish makes the second pipette end load onto in advance and extend the supernatant fluid slowly sucking-off wherein containing plasmid DNA in a centrifuge tube, rotate again and move liquid dish and will slowly be added in No. two DNA adsorption columns containing the supernatant fluid of plasmid DNA in the second pipette, same use second pipette is by the liquid sucking-off in No. three centrifuge tubes and transfer in No. four DNA adsorption columns, then centrifugal, at this moment plasmid DNA to be adsorbed onto in DNA adsorption column on DNA binding film, and the waste collection filtered is in the bottom of DNA adsorption column.Then rotate move liquid dish make the 4th liquid adding bottle move to successively No. two DNA adsorption columns and No. four DNA
