Abstract: A nucleic acid extraction device for molecular testing comprises a film-flipping mechanism, a cap mechanism, a dispensing mechanism, an extraction plate transfer mechanism, and a nucleic acid extraction module. A sealing film is adhered onto top of an extraction plate and folded along an outer edge of the extraction plate. A film-flipping head of the film-flipping mechanism abuts against a bottom surface of the extraction plate and pushes an edge of the sealing film to unfold the sealing film. A film gripper clamps and removes the unfolded sealing film. The cap mechanism opens the specimen containers. The dispensing mechanism transfers the specimens from the specimen containers to the extraction plate. The extraction plate transfer mechanism moves the extraction plate with the specimens to the nucleic acid extraction module. As a result, molecular testing is automated to reduce labor and improve quality.

Abstract: A cell and medicament dispensing device for drug screening is configured to dispense minute amount of cells and medicaments. The device has a base, a transfer plate serving mechanism, a transfer plate positioning mechanism, an injection mechanism, a cell culture plate positioning mechanism, and a dispensing mechanism. The transfer plate serving mechanism moves a transfer plate to the transfer plate positioning mechanism. The injection mechanism injects cells and medicaments into recesses in the transfer plate. A cell culture plate is fixed in the cell culture plate positioning mechanism. The dispensing mechanism moves back and forth between a position above the transfer plate and a position above the cell culture plate to dispense the cells or medicaments from the transfer plate to the cell culture plate. As a result, the process of drug screening is automated to reduce labor and improve quality significantly.

Abstract: A pipette-tip connecting device has a base, a first positioning mechanism, a second positioning mechanism, a connecting seat, a pipette-fixing seat, and a tilt actuator. The first positioning mechanism extends along a first direction. The second positioning mechanism is linked to the first slider and extending upward and downward along a second direction. The connecting seat is mounted on the second slider such that positions of the connecting seat along the first direction and the second direction are controlled by the first positioning mechanism and the second positioning mechanism respectively. The pipette-fixing seat is mounted on the connecting seat and is pivotal relative to the connecting seat. The pipette-fixing seat has a pipette-tip connector which moves in the first direction and the second direction when the pipette-fixing seat pivots. The tilt actuator controls a relative angle between the pipette-fixing seat and the connecting seat.
