Efficient and convenient suction filtration device

Abstract

The invention discloses an efficient and convenient suction filtration device. The efficient and convenient suction filtration device is characterized in that the efficient and convenient suction filtration device comprises a filter cup for storing a to-be-filtered water sample, a liquid collection bottle connected with the bottom of the filter cup through a hollow filter pipe, filter membrane card modules arranged in the hollow filter pipe, and an outer sleeve which is connected with the filter cup and the liquid collection bottle and is arranged outside the hollow filter pipe; a vacuum pumpconnected through an exhaust pipe is arranged on the liquid collection bottle; the plurality of filter membrane card modules are arranged in the hollow filter pipe in the axial direction of the hollowfilter pipe; and filter membranes used for collecting plankton are arranged on the filter membrane card modules. By adopting the above structure, the plurality of filter membrane card modules are loaded, so that researchers can filter and collect aquatic planktons with different particle sizes at one time, water sample suction filtration efficiency is improved, and cost is saved.

Description

technical field [0001] The invention relates to a high-efficiency and portable suction filtration device, in particular to a high-efficiency and convenient suction filtration device that satisfies researchers for filtering and collecting aquatic plankton of different particle sizes at one time. Background technique [0002] Aquatic microbial research is full of new opportunities, but also faces new challenges. The study of aquatic microorganisms provides solutions to the crises our society is facing today, and plays an irreplaceable role in solving human crises. The research prospects of aquatic microorganisms are very broad, and will serve more aspects of human beings in the future, so we must continue to study aquatic microorganisms in depth and contribute to the sustainable development of human society. In today's society, people's demands on the earth are increasing day by day. With the development of aquatic microbial technology, people have turned their attention to ...
