  • Patent number: 10620097
    Abstract: A biological sample processing device includes a base, a purification unit, a metering unit and a first tube. The purification unit is disposed on the base and is configured to purify a sample. The metering unit is disposed on the base and has an inlet, at least one metering trough and an overflow trough. The inlet is connected to the purification unit via the first tube, and the metering trough is connected between the inlet and the overflow trough. The sample from the purification unit is configured to enter the metering unit through the inlet to be moved toward the metering trough, and to be moved toward the overflow trough after the metering trough is filled with the sample.

  • Patent number: 10455985
    Abstract: A mixing vessel includes a vessel body, a clamping device and a stirrer. The vessel body includes a bottom panel and a vessel wall upwardly extended from the border of the bottom panel. The bottom panel defines a top surface, an opposing bottom surface and an opening cut through the top surface and the bottom surface. The clamping device is connected to the bottom panel of the vessel body and clamped on the top surface and the bottom surface of the bottom panel. The stirrer is inserted through the opening of the bottom panel of the vessel body and connected to the clamping device. Thus, subject to fixation of the clamping device to the bottom panel of the vessel body, the mixing vessel presents the bottom panel of the vessel body from deformation due to heat.

  • Patent number: 10005658
    Abstract: A water dispenser includes a main body and a water container. The main body has a receiving space and a connecting socket. The water container includes a container body and a water dispenser connector. The container body has a receiving chamber for storing a liquid. The water dispenser connector is connected to the container body and located at a bottom portion of the container body. When the water container is mounted in the receiving space of the main body, with the water dispenser connector connected to the connecting socket of the main body, the liquid in the receiving chamber of the container body can flow through the water dispenser connecter to the connecting socket of the main body. Once the water container is detached from the main body, the water dispenser connector stops the liquid from flowing out of the receiving chamber of the container body.

  • Patent number: 9756984
    Abstract: A container includes a blending base, an internal wall surface, and an internal bottom surface. The blending base is formed inside the container, extending upward slantwise from a peripheral edge of the internal bottom surface to the internal wall surface. The blending base includes a plurality of turning portions and extended curves at a top edge thereof. The extended curves are linked with the turning portions and cling to the internal wall surface. Thus, the blending base does not adversely affect the appearance of the container and can enhance the blending effect. In addition, the container can be washed and cleaned easily due to the blending base.
