Description

Technical Field

[0001] The utility model relates to the technical field of nucleic acid aerosol processing, in particular to a laboratory nucleic acid aerosol collector. Background Art

[0002] Aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gas medium. The density of these solid or liquid particles may differ slightly or greatly from that of the gas. When conducting PCR nucleic acid tests and experiments, aerosols are formed when air rubs against the liquid surface. Therefore, violent shaking of the reaction tube, sampling when opening the lid, and repeated sampling can all cause nucleic acid aerosol contamination. At this time, a nucleic acid aerosol collection and processing device is needed to collect and process the nucleic acid aerosol in the laboratory.

[0003] Some nucleic acid aerosol collection and processing devices currently on the market: for example, the utility model patent with authorization announcement number CN218001725U discloses a device for purifying nucleic acid aerosol pollution in the air. The device cooperates with a high-voltage electric field component and an ultraviolet light source to circulate and purify the inhaled contaminated air. However, since the device can only collect and process the nucleic acid aerosol at the location, the collection and processing effect and efficiency of the nucleic acid aerosol are poor and need to be improved.

[0004] So we proposed a laboratory nucleic acid aerosol collector to solve the problems raised above. Utility Model Content
