Abstract

The invention discloses a liquid-separatable centrifuge tube, which is composed of a tube body and a switch part, wherein the bottom of the tube body has a drum-shaped piston cavity, the upper and lower ends of the piston cavity are small and the middle is raised, and the bottom of the tube body has drainage holes , the drainage hole communicates with the space of the pipe body and the side wall of the piston chamber, the upper part of the switch part is a drum-shaped piston matching the piston chamber, there is a fluid channel in the switch part, the fluid channel connects the side wall of the piston and the bottom of the switch part, and the drainage hole is in the piston chamber The horizontal position of the side wall outlet is consistent with the horizontal position of the fluid channel at the side wall outlet of the piston. The piston is placed in the piston cavity. By turning the switch part, the fluid channel can communicate with the drainage hole, so that the liquid can flow out from the bottom of the switch part. The liquid-separable centrifuge tube of the present invention prevents liquid leakage during centrifugation, and is particularly suitable for centrifugal liquid-separation operations.

Description

technical field [0001] The invention relates to the technical field of extraction, in particular to a liquid-separatable centrifuge tube. Background technique [0002] Extraction is an experimental technique widely used in chemistry, chemical engineering, biology, medicine and other fields. During the experiment, it is often necessary to use a centrifuge to accelerate the centrifugation of the experimental object to promote the stratification of the mixed solution in a short time. Most of the test tubes used in the laboratory are bottom-sealed and cannot be used for liquid separation; the separatory funnel used can only be used for liquid separation and cannot be used for centrifugation. Centrifugal liquid separation is a very important link in the experimental process. Due to the various drawbacks of the test tubes and separatory funnels currently used, the centrifugal liquid separation of the mixed system is very complicated, resulting in a lot of time wasted on the centr...
