Description

Technical Field

[0001] The utility model belongs to the technical field of processing equipment, in particular to a sample processing device for detecting plant genetically modified components. Background Art

[0002] Existing technologies for detecting genetically modified components mainly detect nucleic acids or proteins. The main process of nucleic acid-based detection methods is: extracting nucleic acids from the sample to be tested, amplifying the genetically modified components in the sample using the PCR (Polymerase Chain Reaction) method, and detecting the presence of genetically modified components using real-time quantification, agarose electrophoresis or chip technology. During the detection process, the sample needs to be processed, which requires the use of a sample processing device.

[0003] In the current existing technology, when processing samples, the samples need to be centrifuged, which requires the use of centrifugal processing equipment. The centrifugal processing equipment places the sample in a centrifugal processing device and performs rotational centrifugal processing, making it easier for users to extract plant genetically modified components for testing.

[0004] However, when rotating the sample, the existing sample processing device has a poor limiting effect on the sample, causing the sample to change position, thereby affecting the centrifugal processing of the sample and affecting the detection of genetically modified components in the sample. Therefore, to address the above problem, a sample processing device for detecting genetically modified components in plants is proposed. Utility Model Content
