Problems solved by technology

[0002] In the existing laboratory, a large amount of fluid solutions such as tissue culture fluid are filtered naturally through the filter membrane in the clean room. Due to the large space of the clean room, the maintenance and manufacturing costs are high. For experiments that require a large number of filtration operations, It prolongs the experimental process and makes the operator less efficient

Abstract

The invention provides a vacuum filter, which is characterized in that a mass of filtering of fluid solution such as a tissue culture solution can be completed by an operator without a clean room, cleanliness degree is ensured, the experiment flow is shortened, and the work efficiency of the operator can be increased. The vacuum filter comprises an upper cup and a lower reception bottle, the upper part of the upper cup is provided with a lid, the vacuum filter is characterized in that a filtering apparatus is arranged between an lower outlet of the upper cup and an upper inlet of the lower reception bottle, the inlet of the filtering apparatus is connected to the lower outlet of the upper cup, the outlet of the filtering apparatus is communicated with the upper inlet of the lower reception bottle, a filter membrane is arranged in the filtering apparatus, a pipe joint is arranged at the side part of the filtering apparatus, one end of the pipe joint is communicated with an internal cavity of the filtering apparatus, and the other end of the pipe joint is externally connected to a vacuum pump.

Description

technical field [0001] The invention relates to the technical field of cell culture structures, in particular to a vacuum filter. Background technique [0002] In the existing laboratory, a large amount of fluid solutions such as tissue culture fluid are filtered naturally through the filter membrane in the clean room. Due to the large space of the clean room, the maintenance and manufacturing costs are high. For experiments that require a large number of filtration operations, It prolongs the experimental process and makes the operator's work efficiency low. Contents of the invention [0003] In view of the above problems, the present invention provides a vacuum filter, which allows the operator to complete a large amount of filtration of fluid solutions such as tissue culture fluid without being in a clean room, and ensures cleanliness, thereby shortening the experimental process and improving operation. staff productivity. [0004] A vacuum filter, its technical s...
