  • Patent number: 11761974
    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.

  • Patent number: 8986982
    Abstract: A thermal cycle system and method suitable for mass production of DNA comprising a temperature control body having at least two sectors. Each sector has at least one heater, cooler, or other means for changing temperature. A path traverses the sectors in a cyclical fashion. In use, a piece of tubing or other means for conveying is placed along the path and a reaction mixture is pumped or otherwise moved along the path such that the reaction mixture is repetitively heated or cooled to varying temperatures as the reaction mixture cyclically traverses the sectors. The reaction mixture thereby reacts to form a product. In particular, polymerase chain reaction reactants may continuously be pumped through the tubing to amplify DNA. The temperature control body is preferably a single aluminum cylinder with a grooved channel circling around its exterior surface, and preferably has wedge-shaped or pie-shaped sectors separated by a thermal barrier.

  • Patent number: 8246919
    Abstract: A rack for a plurality of capped tubes, including a frame having a longitudinally extending bottom base member having a row of spaced open top recesses adapted to receive the capped tubes. Vertical supports at the ends of the row of recesses fix a cover member above the base member. The cover member has openings therethrough smaller than the capped tubes. A wall is along one longitudinal side between the base member and the cover member, with the other longitudinal side between the base member and the cover member being open. Support fingers extend horizontally from the wall toward the open longitudinal side and are vertically aligned between the recesses to secure capped tubes in a generally vertical direction in a longitudinally extending vertical plane. The base member and cover member are vertically spaced a distance sufficient to permit tipped capped tubes to be moved into the frame with the tipped tubes then dropped into the recesses and tipped back to an upright vertical position.

  • Patent number: 8080411
    Abstract: Disposable units in current use for performing PCR are limited by their heat block ramping rates and by the thermal diffusion delay time through the plastic wall as well as by the sample itself. This limitation has been overcome by forming a disposable plastic chip using a simple deformation process wherein one or more plastic sheets are caused, through hydrostatic pressure, to conform to the surface of a suitable mold. After a given disposable chip has been filled with liquid samples, it is brought into close contact with an array of heating blocks that seals each sample within its own chamber, allowing each sample to then be heat treated as desired.

  • Patent number: 8017383
    Abstract: A solution temperature control device in a biological cell observing chamber (30) used for the detection of chemotaxis and chemotactic cell separator, comprising a first temperature controller (62) and a second temperature controller (63). The first temperature controller (62) measures the temperature of a solution filled in a pair of wells and a flow passage in the chamber and controls the temperature to a specified temperature, and the second temperature controller (63) measures the temperature of a heating part (64) which heats the chamber (30) from the outside to indirectly heat the solution filled in the pair of wells and the flow passage and controls the temperature to a specified preheat temperature. Since the state and quantity of cells moving from one well to the other through the flow passage while holding the temperature of the solution at a specified temperature can be accurately observed and measured, accuracy for controlling the temperature of the solution can be remarkably increased.
