Abstract

The present invention provides a negative pressure collecting apparatus and a negative pressure collecting method. According to the apparatus, a sucking chamber is formed inside the box body of the negative pressure collecting apparatus; the box body is provided with at least a first placing hole; a placing cover covers the box body, and is provided with at least a through second placing hole; a collecting pipe is inserted into the first placing hole; an adsorbing column is inserted into the second placing hole; a gas sucking gap is arranged between the discharge port of an adsorbing port andthe inlet of the collecting pipe; the sucking chamber is communicated to the gas sucking gap; and a negative pressure sucking device is communicated to the sucking chamber, and is used for sucking thegas in the sucking chamber. With the apparatus and the method of the present invention, the macromolecule adsorbed on the adsorbing column is sucked by using the negative pressure, and is collected into the collecting pipe, such that the negative pressure sucking and collecting experiment becomes possible, the experimental effect is good, and the use is convenient; and the negative pressure collecting apparatus can treat a plurality of adsorbing columns at the same time, and the plurality of the adsorbing columns do not pollute each other, such that the experiment efficiency is high.

Description

technical field [0001] The invention relates to a negative pressure collecting device. [0002] The present invention also relates to a negative pressure collection method using the above negative pressure collection device. Background technique [0003] Macromolecular preparations, such as proteins, nucleic acids, polysaccharides, etc., need to be purified before use. For example, when nucleic acid is purified, the nucleic acid is first cleaned, and the cleaned nucleic acid is adsorbed on the adsorption column. At this time, it is necessary to collect the nucleic acid adsorbed on the adsorption column into a collection tube. The collection method can be negative pressure suction, but there is still a lack of matching experimental devices with better performance on the market. Contents of the invention [0004] The object of the present invention is to provide a negative pressure collection device and a negative pressure collection method, so as to achieve the purpose of...
