[0002] Centrifuge tubes are tools that centrifuge reagents into layers. Depending on the way they are used, centrifuge tubes can be plastic, glass, or steel. Steel centrifuge tubes are strong, non-deformable, heat-resistant, freeze-resistant, and chemically corrosion-resistant. They are widely used, but when used, they should also avoid contact with highly corrosive chemicals, such as strong acids and alkalis. Try to avoid corrosion from these chemicals.

[0003] The existing stainless steel centrifuge tubes on the market are of one-piece design and have no filtering function. Under high-speed centrifugation conditions, they can only separate materials into layers but cannot achieve separation effects. Utility Model Content

[0004] The utility model provides a stainless steel high-speed centrifugal filter tube, which is used to solve the technical problems raised by the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model provides a stainless steel high-speed centrifugal filter tube, comprising an upper tube body, a lower tube body and a bottom cover, the upper tube body is round-bottomed, the lower tube body is flat-bottomed, and the bottom cover can be detachably installed under the lower tube body, and the upper tube body can be detachably installed above the lower tube body, a filter plate is provided inside the upper tube body, and filter holes are opened on the filter plate, and a plurality of filter holes are provided, and the plurality of filter holes are evenly arranged.

[0006] Preferably, a threaded connector is fixedly installed at the bottom of the lower tube body, a threaded groove is provided at the connection between the upper tube body and the lower tube body, and the upper tube body and the lower tube body are meshed.

[0007] Preferably, an outer side of the lower portion of the lower tube body is processed with an external thread, an inner side of the bottom cover is processed with an internal thread, and the lower tube body is meshingly connected with the bottom cover.

[0008] Preferably, the outer diameter of the filter plate is consistent with the inner diameter of the upper tube body, that is, the filter plate is overfitted with the upper tube body.

[0009] Preferably, the upper tube body, the lower tube body and the bottom cover are all made of stainless steel.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The utility model discloses a stainless steel high-speed centrifugal filter tube, which is connected in three sections by an upper tube body, a lower tube body and a bottom cover, and a filter plate is clamped on the top of the upper tube body. During the centrifugation process, the filter plate can be used to perform layered filtration, thereby achieving a separation effect. BRIEF DESCRIPTION OF THE DRAWINGS
