Problems solved by technology

[0002] At present, the low-pressure chromatography column in the prior art has a relatively simple filtration structure, and the filtration is not fine enough. Moreover, due to the inconvenient adjustment of the height of the column bed, the compaction force on the packing surface cannot be adjusted accurately, which is very inconvenient to use.

Embodiment Construction

[0022] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0023] Such as figure 1 , 2 Shown, a kind of low-pressure chromatography column, it comprises body, it also comprises:

[0024] A cylinder body 1, the cylinder body 1 is provided with a filler chamber 11 for accommodating fillers;

[0025] The piston part includes a piston assembly and is connected with the piston assembly so as to drive the piston assembly to move, so that the piston assembly is pressed into the packing chamber 11 and acts on the packing. The piston assembly is provided with a piston assembly for pressing the piston assembly When the inlet is in place, the liquid phase is guided to the upper surface of the packing in the packing cavity;

[0026] A liquid distribution assembly for collecting the liquid phase flowing out of the p...

Abstract

The invention discloses a low pressure chromatography column. The column comprises a body, and further comprises a cylinder, a piston part, and a liquid dispensing assembly for collecting the dispensed liquid flowing from the liquid phaseof the filler in a filler cavity. The cylinder is provided with the filler cavity for accommodating the filler. The piston part comprises a piston assembly and apiston drive assembly connected to the piston assembly to drive the piston assembly to move so that the piston assembly is pressed into the filler cavity to act on the filler. The piston assembly is provided with an infusion distribution component guiding the liquid phaseto the upper surface of the filler in the filler cavity when the piston assembly is pressed in the right place.According to theinvention, the height of a column bed can be adjusted based on requirements, the pressing force on the surface of the filler is precisely controlled, so that the pressure acting on the surface of thefiller is more balanced, and a filtering effect is better.

Description

technical field [0001] The invention relates to a low-pressure chromatographic column. Background technique [0002] At present, the low-pressure chromatographic column of the prior art has a relatively simple filtration structure and is not fine enough for filtration. Moreover, due to the inconvenient adjustment of the height of the column bed, the compaction force on the surface of the packing cannot be accurately adjusted, which is very inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a low-pressure chromatography column, which can adjust the height of the column bed according to the needs and precisely control the compacting force on the surface of the packing, so that the pressure acting on the surface of the packing The pressure is more balanced and the filtering effect is better. [0004] In order to solve the above-mentioned technical problems...
