Automatic liquid change: after the stirring is accomplished, the operating personnel will trade the interior extension group 13 of liquid and be connected with reaction barrel 8 through joint and clamp, start first peristaltic pump 4 and take out the solution after will stirring for the first time from reaction barrel 8, flowmeter 3 is used for monitoring the flow of discharge liquid, turbidity appearance 2 is used for the turbidity of detection thing liquid, can know the weight of discharge liquid through weighing module 19, after the solution after the first stirring is discharged, start second peristaltic pump 9 and carry the thing liquid to reaction barrel 8, realize changing liquid automatically.
5. After the solution is changed, the solution in the reaction barrel is stirred, magnetically separated and changed again, and the magnetic bead mother solution meeting the requirement is obtained after the solution is changed for a proper time according to the production requirement.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
