  • Publication number: 20060246487
    Abstract: Provided is an apparatus for performing a chemical reaction using a microchip having at least one micro-channel. The device, which is a semiautomatic operating device for a microchip on which at least one micro-channel with a reagent inlet is formed, includes: a base which accommodates the microchip; a slider with injection inlets corresponding to the reagent inlets that reciprocally move parallel to the base; and a slider moving unit which selectively moves the slider to a first location at which the microchip is opened, after the injection inlet of the slider and the reagent inlet are aligned, and to a second location where the microchip is sealed by a bottom surface of the slider covering the reagent inlet.

  • Publication number: 20060246580
    Abstract: Provided are a polymerase chain reaction (PCR) module and a PCR system including the same. The PCR module includes: a detachable PCR chip including a PCR chamber unit in which a PCR solution is accommodated; a heater unit for heating the PCR solution in the PCR chip with a preset temperature; a detecting unit for detecting a PCR signal of the PCR solution; a PCR chip installation unit for mounting/detaching the PCR chip using a one-touch method, in which the heater unit is adhered to the PCR chip with a predetermined pressure when mounting the PCR chip and the heater unit is separated from the PCR chip when detaching the PCR chip; and a housing covering at least the heater unit and the detecting unit so that they are not exposed to the outside.

  • Publication number: 20060193751
    Abstract: A packing device used to pack a sample inlet formed in an upper cover of a chamber is provided. The packing device has an air vent formed in the surface of an upper portion of the sample inlet contacting a cap or in the surface of a lower portion of the cap contacting the sample inlet. The movement of the sample solution in the chamber can be prevented by using a structural design in which air pressure generated due to the volume of a packing cap inserted into the sample inlet after the sample is injected into the chamber through the sample inlet to react with reaction materials, such as biomolecules, is not generated inside of the chamber. In addition, in a hybridization chamber in which a biochip is placed, the spot area on the biochip can be effectively agitated with the sample solution, thus increasing hybridization efficiency.

  • Publication number: 20060078931
    Abstract: Provided is a microchip unit, including a microchip on which a plurality of micro-channels are formed, a housing disposed below the microchip to fix the microchip; and at least two injecting and sealing elements having through-holes corresponding to inlets of the microchip. The injecting and sealing elements are vertically fixed on the top of the housing and slide in a horizontal direction from a first location to a second location and vice versa. The through-holes are aligned with inlets of the microchip so that a reaction solution can be injected through the through-holes when the injecting and sealing elements are placed at the first location. The inlets of the microchip are sealed by elastic members formed on bottom surfaces of the injecting and sealing elements when the injecting and sealing elements are placed at the second location.
