Abstract

The invention discloses a high-flux automatic opening and closing type filtering suction head which comprises a liquid outlet pipe, a liquid pumping pipe and floating filter element cotton, the liquid outlet pipe comprises a first connecting section, a second connecting section and a third connecting section, the first connecting section, the second connecting section and the third connecting section are sequentially arranged from top to bottom and integrally connected, the first connecting section is of a hollow cylindrical structure, the second connecting section and the third connecting section are each of a hollow conical structure, the first connecting section, the second connecting section and the third connecting section internally communicate with one another, a liquid outlet is formed in the bottom of the third connecting section, the floating filter element cotton is movably clamped at the joint of the second connecting section and the third connecting section, the size of the floating filter element cotton is matched with that of the joint of the second connecting section and the third connecting section, a limiting groove is formed in the top end face of the floating filter element cotton, and the liquid pumping pipe is slidably connected into the first connecting section. The filtering suction head is simple in structure, reasonable in design, convenient to operate, short in extraction period, high in extraction efficiency and low in extraction cost, and has a good application prospect.

Description

technical field [0001] The invention relates to the technical field of biotechnology and clinical sample processing, and more specifically relates to a high-throughput automatic opening and closing filter tip. Background technique [0002] The membrane filtration method refers to the use of positive pressure or centripetal force to make the protein solution pass through the Dow reverse osmosis membrane with a certain cut-off relative molecular mass to achieve the purpose of extracting the protein solution. Although the membrane filtration method can achieve the extraction of protein aqueous solution to a certain extent, it often has the disadvantages of high cost, complicated purification steps, and long time. [0003] Therefore, it is an urgent problem for those skilled in the art to provide a high-throughput automatic opening and closing filter tip with simple structure, reasonable design, convenient operation, short extraction cycle, high extraction efficiency and low cos...
