Abstract: The present invention provides a device capable of conducting magnetic solid-phase extraction, including a framework assembly. The framework assembly includes a platform assembly and an electrical cabinet assembly. The electrical cabinet assembly is disposed below the platform assembly, and an electric assembly is packaged in an electrical cabinet of the electrical cabinet assembly. The electric assembly is disposed independent from the platform assembly. Data wires connected to the electric assembly and the platform assembly are placed in the framework frame or a sheet metal structure, preventing reagents and operations on the platform assembly from polluting or affecting the electric assembly. The present invention designs a magnetic solid-phase extraction device. Pretreating samples in a manner of magnetic solid-phase extraction simplifies the extraction process, reduces the processing costs of the device, and overcomes negative effects caused by some other extraction methods in the background.
