Filtering device for biochemical experiment

Abstract

A filtering device for a biochemical experiment comprises a mounting base, a first container is arranged on the mounting base, a second container is arranged above the first container, the height of the second container relative to the first container can be adjusted, the second container is connected with a plurality of filtering units, and the filtering units are connected with the mounting base. The filtering unit is arranged higher than the second container in a normal state, the height position of the filtering unit can be adjusted, liquid flowing into the second container from the first container or liquid flowing into the first container from the second container can be filtered, and the filtering unit has multiple specifications and can be replaced. According to the present invention, the common filtration process can be completed, according to the relative position of the first container and the second container, a variety of different filtration modes can be selected, different filtration units can be selected, and different filtration experiments can be performed, for example, after the filtration unit of the apparatus uses the semipermeable membrane as the filtration layer, the filtration of the protein can be completed.

Description

technical field [0001] The invention relates to the field of biology, in particular to a filter device for biochemical experiments. Background technique [0002] Filtration is the most commonly used operating method for separating solutions and precipitates. When the mixture of solution and precipitate passes through a filter, such as filter paper, the precipitate remains on the filter and the solution passes through the filter into a receiving container. Filtration in the traditional sense refers to the method of using porous media to intercept solid particles in suspension, and then separate solid and liquid. In addition to centrifugation, bacteria, cells and their fragments can also be separated by conventional filtration. Therefore, the filter device is a very commonly used device in biochemical experiments. [0003] However, the existing filtration devices are basically only fixed on the filtration of conventional solutions, and new equipment is required for protein ...
