Problems solved by technology
Its shortcoming is: (1) the filtrate that suction filtration obtains is collected in the suction filtration bottle, when the experiment needs to carry out the suction filtration of a large amount of different samples, every time changing a kind of liquid to be suction filtered just need to clean once suction filtration bottle; (2) Multiple sets of funnels cannot be used for suction filtration at the same time
Therefore, the working efficiency of the existing laboratory suction filtration device is relatively low

The invention discloses a box type rapid suction filtration device applicable to a laboratory. The box type rapid suction filtration device comprises a suction filtration box, an air exhausting nozzle, a box cover, a plurality of groups of suction filtration assemblies, an air exhausting pipe and a vacuum pump, wherein the box cover covers the upper end of the suction filtration box; the plurality of groups of suction filtration assemblies are arranged on the box cover respectively; each suction filtration assembly comprises a suction filtration funnel and a sealing valve; each suction filtration funnel is arranged on the box cover and the lower part of each suction filtration funnel penetrates through the box cover to be located in the suction filtration box; each sealing valve is arranged on the corresponding suction filtration funnel and is located above the box cover; the air exhausting nozzle is arranged on the suction filtration box; and one end of the air exhausting pipe is in sealed connection with the vacuum pump. According to the box type rapid suction filtration device, the plurality of groups of suction filtration assemblies are arranged so that the plurality of groups of funnels can be used for sucking and filtering at the same time, and independently controlling; a replaceable filtrate collection bottle is arranged so that the work of repeatedly washing the filtrate collection bottle can be avoided, and therefore, the liquid sample suction filtration efficiency is remarkably improved; and the box type rapid suction filtration device is particularly suitable for sucking and filtering filtrate in batches in the laboratory.
Description
technical field [0001] The invention relates to a filter device, in particular to a box-type rapid suction filter device suitable for laboratory use. Background technique [0002] The existing laboratory suction filtration device is that a suction filtration funnel is installed on a suction filtration bottle, and the suction filtration effect is achieved by connecting the suction filtration bottle and the vacuum pump through a hose. Its shortcoming is: (1) the filtrate that suction filtration obtains is collected in the suction filtration bottle, when the experiment needs to carry out the suction filtration of a large amount of different samples, every time changing a kind of liquid to be suction filtered just need to clean once suction filtration bottle; (2) Multiple groups of funnels cannot be used for suction filtration at the same time. Therefore, the working efficiency of the existing laboratory suction filtration device is relatively low. Contents of the invention ...
