The application discloses a centrifugal tube and assembly for making cell wax blocks. The centrifugal tube comprises a ball-sac-equipped inner thread top cover, a centrifugal tube body composed of a funnel part and a cell enrichment tube, a cell collection capsule, a bottom pad and a bottom-sealed inner thread cover. The cell collection capsule and the bottom pad are arranged inside the cell enrichment tube to collect cells and can be taken in and out of the lower opening of the cell enrichment tube. After installation, detection liquid is added to the centrifugal tube body, and the centrifugal tube body is centrifuged by a centrifugal machine. The cells in the liquid are settled in the collection capsule. The bottom thread cover is unscrewed, the ball sac is pressed, and the cell collection capsule with the internal cell sediment is discharged from the lower opening of the cell enrichment tube under the hydraulic action. Then, the cell collection capsule is taken with the capsule cap and is placed in 10% neutral formalin solution for fixation.

This utility model relates to the field of cell disruption device technology, specifically a high-efficiency continuous cell disruption device, including a cell disruption device body. A cell disruption component is installed at the front end of the cell disruption device body, and a telescopic cylinder is fixedly installed on the side of the cell disruption component. By placing the cell environment on the placement seat, the cells are positioned above the disruption device body. Then, a signal is transmitted from the cloud to the cell disruption device body, causing the lateral positioning end to slide on the side of the adjustment track, moving the cell disruption component to the cell placement seat position. After the anesthetized cells are disrupted, the cell disruption component controls the telescopic cylinder to drive the telescopic rod to descend, moving its end disruption device to the appropriate disruption position. The adjustment key block slides down to disrupt the internal cells. The auxiliary disruption disc stabilizes the telescopic rod, preventing shaking during disruption, thus making the whole device very stable, reliable, and flexible.

This utility model relates to the field of fruit harvesting technology. It discloses a storage box for fruit harvesting, comprising a box body, six movable plates, movable holes, a rotating rod, and two handles. The movable plates are movably connected to the inner cavity of the box body, and the movable holes are located on the side of the box body near the movable plates.
