Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal washing, in particular to centrifugal washing equipment for ferroferric oxide nano-microspheres. Background Art

[0002] Centrifugal washing is a separation and cleaning technology that uses centrifugal force to separate solid matter and liquid in the sample. The specific operation steps are to add the sample to the centrifuge tank, then add an appropriate amount of solvent, and after high-speed centrifugation, the solid matter suspended in the liquid will be precipitated to the bottom of the tube, and then the upper liquid will be poured out. Repeat this step several times, and finally clean solid matter can be obtained. Centrifugal washing is widely used in chemistry, biology, pharmacy and other fields, such as separating biological molecules such as DNA and proteins.

[0003] The Chinese patent publication number is CN203360852U, and the authorization announcement date is December 25, 2013. An adaptive centrifugal washing device includes an inner cylinder, a pulsator is arranged at the bottom of the inner cylinder, a driver for driving the pulsator is arranged below the inner cylinder, a small hole is opened in the center of the pulsator, a column is vertically arranged at the bottom of the inner cylinder through the small hole, a rubbing roller in the form of a hollow cylinder is sleeved on the column, bar magnets with the same polarity pointing to the axis are evenly distributed on the rubbing roller, and polar magnets are arranged on the circumference of the outer side of the inner cylinder. A permanent magnet or electromagnet pointing to the axis of the rubbing roller, the permanent magnet or electromagnet is rotated around the outer side of the inner drum by a driving device.
