Multi-channel parallel pretreatment device

A multi-channel parallel pretreatment device, comprising a magnetic separation and transfer device configured to perform separation and transfer and a first drive device configured to drive the magnetic separation and transfer device to move, wherein

• the magnetic separation and transfer device comprises a second mounting bracket;
• the second mounting bracket is provided therein with an injector chamber;
• a mounting plate is provided above a top of the injector chamber and is provided with piston rods;
• the piston rods are connected to the injector chamber in a movable and sealing manner;
• and the second mounting bracket is further provided thereon with a second drive device;
• the second drive device is configured to drive the mounting plate to linearly reciprocate in a vertical direction;
• the injector chamber is provided with loading heads;
• each of the loading heads is configured to load a tip head or a magnetic separation sleeve and has a hollow structure;
• and
• free ends of the piston rods are fixedly connected to magnetic rods;
• the magnetic rods are configured to adsorb magnetic beads in a magnetic particle reagent;
• and the second drive device is configured to drive the magnetic rods on the piston rods to pass through the loading heads.
