Abstract: The present invention relates to a suction dispensing device having a removable tip, which can suction or dispense liquid by allowing a dispensing tip to be mounted thereon and can automatically remove the mounted dispensing tip, the device comprising: a driving base module which raises and lowers a movable plate; and a syringe operation module having at least one syringe installed therein so that when the movable plate rises from a reference position to a suction position, liquid can be suctioned therein, and when the movable plate returns to the reference position from the suction position, the liquid can be dispensed, wherein, in the syringe operation module, when the movable plate moves downward from the reference position to a tip removal position, a tip removal plate may be formed so that the dispensing tip forcefully engaged in the front end of the syringe can be removed.

Abstract: The present invention relates to a complex sample pretreatment apparatus that enables extraction of a DNA or RNA component from a complex sample, such as excretion, which is a mixture of liquid and solid phases, through a series of pretreatment processes. The apparatus may comprise: a housing; a cartridge seating device which is installed inside the housing and onto which a cartridge is seated; a spin drive device which is installed in the housing, is coupled to an object to be spun which is mounted on the cartridge or mounted on the cartridge mounting device, and rotates the object to be spun; and a pump drive device which is installed in the housing, is coupled to a dispensing tip mounted on the cartridge or on the cartridge mounting device, and dispenses a sample or reagent by using the dispensing tip.

Abstract: Provided is a collected sample pretreatment apparatus capable of rapidly and accurately analyzing a deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) sample collected by a swab or another collector, through a series of automated processes, the collected sample pretreatment apparatus including a housing, a cartridge mounting device to hold a cartridge, a spin drive device coupled with a spin tip provided in the cartridge or the cartridge mounting device to rotate the spin tip, a pump drive device coupled with a dispensing tip provided in the cartridge or the cartridge mounting device to dispense a buffer solution by using the dispensing tip, and a tip removal device to remove the spin tip from the spin drive device or the dispensing tip from the pump drive device by using relative motion of the spin drive device and the pump drive device.

Abstract: Provided is a cartridge system for extracting a collected sample. The cartridge system may include: a cartridge body; a dewatering tip-receiving unit in which a dewatering tip is received such that a collecting member to which a sample is collected can be received; a spin cover-receiving unit in which a spin cover is received such that a spin head of a robot device can be equipped with the spin cover; a buffer chamber unit in which a buffer solution is received such that the sample from the collecting member through dewatering by the rotation of the spin head can be received in the buffer solution; and a dispensing tip-receiving unit in which a dispensing tip is received such that a pump head of the robot device can be equipped with the dispensing tip to suction the buffer solution including the sample.

Abstract: The cartridge system for extraction of a complex sample may include: a cartridge body; a complex sample collector for collecting a complex sample to provide same to the cartridge body; a buffer solution receiving unit formed in the cartridge body and configured to accommodate a buffer solution therein and provide a space in which, after a collecting unit of the complex sample collector is immersed in the buffer solution, the collecting unit is rotated by a spin head of a robot device such that the complex sample is mixed with the buffer solution or mixed beads included in the buffer solution; and a complex sample collector disposal unit formed in the cartridge body and configured to temporarily store the complex sample collector to discard same after the complex sample is provided to the buffer solution receiving unit.
