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.

Abstract: A gravitational liquid-splitting device has a funnel, a dispensing valve, a liquid-splitting part, and a stirring assembly. The funnel has an inner space and a bottom opening connected to each other. The dispensing valve is mounted to the funnel and is configured to close or open the bottom opening of the funnel. The liquid-splitting part is connected to a bottom of the funnel and has an input channel and two output channels. The input channel is formed in the liquid-splitting part and extends upward and downward. An upper end of the input channel forms an input opening on a top of the liquid-splitting part and is connected to the bottom opening of the funnel. The stirring assembly has a stirrer configured to stir liquid in the funnel. Therefore, the gravitational liquid-splitting device improves efficiency and quality, and also reduces risk of contamination in the cell passaging operation.

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 living body specimen transport device for receiving multiple living body specimens has a frame, a rotating bracket, and a storage assembly. The rotating bracket can be rotated with respect to the frame. The storage assembly can receive a container with a living body specimen and be rotated with respect to the rotating bracket. A center of gravity of the storage assembly is lower than a pivoting point where the rotating bracket is mounted on the frame and a pivoting point where the storage assembly is mounted on the rotating bracket. With such structure, even when the living body specimen transport device is vibrated and shaken during transporting and then the frame of the living body specimen transport device is tilted or turned over, the rotating bracket and the storage assembly can rotate to be vertical by themselves, which keeps the living body specimen being soaked in the preservation solution.

Abstract: A culture flask has a flask body. The flask body has two translucent planes, one opening end, one recess end and at least one collecting recess. Both translucent planes are located on the opposite ends of the flask body. A collecting recess is formed on the inner surface of the recess end, while the cross sectional area of the recess end gradually decreases toward the bottom of the collecting recess. By forming a collecting recess with decreased cross sectional area, culture cells can be collected inside the bottom after centrifugation, and therefore the user no longer has to transfer the culture cells and culture medium to a centrifuge tube when replacing culture medium. Consumption of suction tube and centrifuge tube can be avoided, the time to replace the culture medium is reduced, and also the risk of contamination when replacing the culture medium is reduced.
