Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further explained, but the utility model is not limited thereto embodiment.
With reference to Fig. 1, be a kind of pretreatment unit checked for lupus cell of the present utility model, comprise magnetic stir bar device and clot smashs sub-device to pieces.
Wherein, magnetic stir bar device comprises the pedestal 1 that can provide rotating magnetic field, is held on the glass container 2 for splendid attire clot of pedestal 1 upper surface, and is placed in the stirrer 3 of the magnetic bar shaped of band in glass container 2.
This glass container 2 is test tube.This pedestal 1 has housing, and this housing is nonmagnetic substance, and the output shaft that housing bottom is provided with output shaft the second motor 4, second motor 4 has upwards been horizontally disposed with bar permanent magnet 5.
