Summary of the invention
The utility model is for solving the defective of the above prior art complex operation, inefficiency, a kind of centrifugal treating is provided and saves as the device of one, it comprises hydro-extractor body and motor, it is characterized in that: also comprise the sample disk assembly, described sample disk assembly comprises sample disk and centrifugal conduit saddle, described centrifugal conduit saddle rotatably is connected on the described sample disk, and described sample disk assembly is installed on the rotation axis of described motor, can make high speed rotating thereupon.
According to embodiment, below the utility model also can adopt preferred embodiment:
Described sample disk is circle or regular polygon, and its edge offers recessed U-shaped breach to the center, and described U is capable, and breach has two or more, evenly distributes.
Described U-shaped breach both sides are near the perforate of end along continuous straight runs symmetry, and described centrifugal conduit saddle both sides along continuous straight runs is symmetrical arranged bearing pin, and described bearing pin inserts respectively in the described hole.
Also be separately installed with axle sleeve in the described hole, described bearing pin inserts in the axle sleeve respectively.
Described centrifugal conduit saddle is the tubbiness of upper end open at least.
Described centrifugal conduit saddle both ends open, wherein the internal diameter of an end is slightly less than the other end.
The inside of described centrifugal conduit saddle also is provided with elastic insert.
Described sample disk assembly is installed on the rotation axis of described motor by the centre of its sample disk.
The beneficial effects of the utility model are:
Sample disk is the centrifugal treating device when rotated, and then as memory storage, thereby centrifugal treating and sample storage is integrated, the operation of saving manual transfer centrifuge tube has improved efficient when stopping.
Circle or regular polygon sample disk, quality evenly distributes, and vibration is little during rotation.
Installation is conveniently processed and is easy in symmetry perforate and bearing pin is set.
Adopt axle sleeve and bearing pin to cooperate, can reduce the wearing and tearing in hole on the sample disk, and axle sleeve is changed convenient and cost is low.
At least at the centrifugal conduit saddle of the tubbiness of upper end open, make things convenient for packing into and taking out of centrifuge tube.
The equal opening in centrifugal conduit saddle two ends, the centrifuge tube that then can lift from the centrifuge tube bottom further facilitates and takes.
Elastic insert can be protected centrifuge tube, makes it to be difficult for broken.
With the sample disk center is rotation center, and balance is good, vibrates little.
