An integrated nucleic acid processing apparatus includes a first operation area, a second operation area and a separation wall. The first operation area includes multiple carrying boards for placing objects and reagents for processing nucleic acids in samples, and multiple operation modules for performing operations of nucleic acid processing. The second operation area includes two extraction regions for respectively performing nucleic acid extractions. The separation wall separates the first operation area from the second operation area and includes two openable door sheets spatially corresponding to the two extraction regions. Nucleic acid extraction plates can be moved from the first operation area to the second operation area by means of the carrying boards as the two openable door sheets are opened, and be isolated in the second operation area for performing nucleic acid extractions as the two openable door sheets are closed.

A sample collection device includes a tube, a closure and a partitioning member. The tube includes an opening and is used to receive a sampling swab. The closure is engaged with the tube for enclosing the opening. The partitioning member is disposed in the tube and includes a blocking portion and a position-limiting portion. The blocking portion is disposed close to the opening and covers a portion of the opening so as to leave another uncovered portion as an entrance for passing the sampling swab therethrough. The position-limiting portion is connected with the blocking portion and extended into the tube, so as to limit the sampling swab in a space corresponding to the entrance inside the tube after the sampling swab passes through the entrance.

An automated liquid handling system includes a transfer robot unit, a handling module, and a fixing unit which is coupled to a head of the robot unit and on which a pipette assembly is to be mounted, wherein the handling module is provided with a mounting part detachably mounted on the fixing unit. The fixing unit includes a body part, a fixing part hook formed at an upper portion of one side of the body part and a lower protrusion disposed at a lower portion of the one side of the body part, the mounting part includes a body, a movable hook part formed at an upper portion of one side of the body and a lower groove formed at a lower portion of the one side of the body to correspond to the lower protrusion, a catching step is formed at the lower groove, and the lower protrusion extends from the lower portion of the one side of the body part to support the catching step from below, and the movable hook part is hook-coupled to a fixing unit hook.

A multifunctional pipette set includes a pipette module, a heater module and a magnetic module. The pipette module includes one or more pipette heads. The heater module has a first joint part, and the heater module configured to removably connect to the pipette module by coupling the first joint part to at least one of the plurality of pipette heads. The magnetic module has a second joint part, and the magnetic module configured to removably connect to the pipette module by coupling the second joint part to at least one of the plurality of pipette heads. The multifunctional pipette set can be further applied in an automatic detection machine.
