Because molecular biology is in the universal and application of every subjects, industry, utilize the sample type of molecular Biological Detection day by day complicated, from cell, bacterium, animal vegetable tissue to soil, environment sample, timber, legal medical expert etc., the problem of sample preparation is also seemed more and more important.
Usually, for the process of sample, generally all comprise the pulverizing of sample and centrifugal.And existing pulverizing and centrifugation apparatus are independent.Therefore the process for sample needs to be equipped with disintegrating apparatus and centrifugation apparatus, and the cost of these two kinds of equipment is relatively high.And when carrying out pulverizing and centrifugal continuous process to sample, need in the expensive time in the transfer of sample, thus, the efficiency of process is general lower.
Summary of the invention
The object of the invention is to, a kind of pulverizing centrifugal method and device of sample is provided.It can make the pulverizing of sample and centrifugally to complete in an equipment, thus saves equipment cost, improves sample preparation efficiency.
Technical scheme of the present invention: a kind of pulverizing centrifugal method of sample, be characterized in: the motor vertically placed with is for power source, drive and rotate with the tilting member that motor upper end is connected with machine shaft, tilting member is tray type structure, and be provided with the fixing station of sample tube, thus sample tube along with tilting member rotates in fixing station, can realize the centrifugal of sample; Between tilting member and motor, rotating disc is set, and rotating disc is connected with pulling parts with tilting member, after braking rotating disc, motor is to the driving force of tilting member and pull the pulling force of parts to tilting member mutually to resist, form vibrations, make the sample in sample tube realize pulverizing under vibrations; When needs centrifugal treating, only need cancel the braking to rotating disc, rotating disc is rotated together with tilting member, thus make to possess at an equipment to pulverize and centrifugal dual-use function.
In the pulverizing centrifugal method of aforesaid sample, described rotating disc is braked by electromagnetic brake.
In the pulverizing centrifugal method of aforesaid sample, arrange electromagnetic clutch between described tilting member and rotating disc, when needs carry out centrifugal treating, electromagnetic clutch does joint action, and electromagnetic brake does separating action; When needs carry out pulverization process, separating action made by electromagnetic clutch, and electromagnetic brake does joint action.
In the pulverizing centrifugal method of aforesaid sample, described in pull parts use Flexible Connector.
Realize the pulverizing centrifugal device of a kind of sample of preceding method, be characterized in: comprise support, upper part of the frame is provided with the rotating disc rotated on support; Rotating disc lower end is provided with vertically arranged motor, and motor is fixed on the motor fixing frame of bottom; The upper end of rotating disc is provided with main shaft, and main shaft connects the rotating shaft of motor, and main shaft is provided with the tilting member of disc type, and tilting member is provided with the fixing station of sample tube; By pulling parts to be connected between rotating disc with tilting member; Also be provided with electromagnetic brake bottom described rotating disc, electromagnetic brake is fixed on brake support frame, and brake support frame and motor fixed rack fix or be structure as a whole.
In the pulverizing centrifugal device of aforesaid sample, between described main shaft lower end and rotating disc, be provided with electromagnetic clutch.
In the pulverizing centrifugal device of aforesaid sample, described in pull parts to be Flexible Connector.The parts that pull of different elasticity coefficient will produce the vibrations of various amplitude, frequency.
Compared with prior art, the present invention increases rotating disc and pulls parts on sample centrifugal treating equipment, and by switching the fixing of rotating disc and rotating, make sample centrifugal treating equipment also can carry out pulverization process, make the centrifugal of sample and pulverize to carry out in same equipment, and without the need to shifting sample.Therefore, the present invention reduces the equipment cost that sample is centrifugal and pulverize greatly, in fact can save almost half equipment cost, and substantially increases centrifugal and pulverize processed continuously speed, processes each time and at least can save 20 minutes.Ingenious part of the present invention is, make use of the interaction pulled between the pulling force of parts and the torque of motor, form vibrations, and then realize pulverizing, so rotating disc only need be increased and pull parts that this equipment can be made to possess crushing function on the basis of sample centrifugal treating equipment, again in conjunction with electromagnetic brake and electromagnetic clutch, can switch between pulverizing and centrifugal function like a cork.
