Abstract: The present invention relates to an airtight apparatus for separating and purifying an extract, comprising: a chamber cartridge having a plurality of chambers for receiving samples and magnetic beads for separation of biological materials; a cover having a bore capable of being introduced into any one of the plurality of chambers, covering the plurality of chambers, and being liftably coupled to the chamber cartridge; a sealing member provided between the cover and the chamber cartridge to maintain airtightness between the cover and a housing; a cover driving part for raising and lowering the cover such that the bore ascends and descends in the chamber; a rod for inserting into and withdrawing from the bore to attach/detach the biological materials adsorbed on the magnetic beads received in the chamber to/from the surface of the bore or to introduce/discharge the samples with the biological materials separated and the magnetic beads into/from the bore; a rod driver for inserting and withdrawing the rod into/f

Abstract: A system for automatically performing the operations of separating and purifying a variety of biological materials for processing nucleic acids or biological materials from biological samples using solid materials. A base plate, a carriage attachment frame assembly including a frame and a plurality of mounting units, a magnetic bar assembly including a frame, a base plate transport unit, a carriage attachment frame assembly transport unit, a magnetic bar transport unit, and a control unit are utilized. A predetermined number and a small amount of samples can be selectively processed in accordance with a user's needs.

Abstract: The present invention relates to a kit for separating and purifying nucleic acids or a variety of biological materials and a system for automatically performing the operations of separating and purifying a variety of biological materials using the kit. The kit of the present invention comprises a container with a plurality of chambers formed in a row for containing buffers and solid materials suitable for separating the nucleic acids or biological materials from the biological samples, and a carriage including a fiat portion with a hole formed therethrough and a projection having an inside passage of which one end is closed and the other end is open and having a predetermined length such that the projection can be dipped into the buffers. A mounting means is formed on the flat portion of the carriage such that the carriage can be detachably mounted to a transport means for transferring the carriage to the respective chambers.

Abstract: The present invention relates to a method of manufacturing a kit for isolating and purifying nucleic acids, or various biological materials, a kit manufactured by the method, and an apparatus using the kit. The method of manufacturing a kit for isolating or purifying nucleic acids or biological materials from biological samples using solid materials comprises the steps of; fabricating a container having a plurality of chambers and/or column which is configured to contain the solid materials, buffers and/or enzymes suitable for isolation of the nucleic acids or biological materials; fabricating a cover including a protruded portion with a bore formed therethrough; filling each of the chambers or column with the solid materials, buffers and/or enzymes for isolation and purification of the biological materials or nucleic acids; sealing the container with a predetermined sealing material; and packaging the cover and the container, one by one, with a separate case.

Abstract: The present invention relates to a kit for separating and purifying nucleic acids or a variety of biological materials and a system for automatically performing the operations of separating and purifying a variety of biological materials using the kit.

Abstract: An automated centrifuge system. The centrifuge includes a rotor in which at least two swing buckets with at least two microplates mounted thereon are provided, a multi-joint robot with at least three joints which includes a gripper attached to a final arm thereof and a finger attached to the gripper, and a controller for controlling the predetermined procedures and operation of the robot. The centrifuge and multi-joint robot are disposed close to each other on a rigid bottom plate. A sensor for use in position detection is attached to the gripper or finger. At least one marker is attached at a predetermined position on a central frame of the rotor.

Abstract: A flat display panel fixing apparatus includes a flat display panel, a back cover on which the flat display panel is fixed by a fastener, and a front cover fixed on the back cover.

Abstract: The present invention relates to an automated centrifuge system for automatically centrifuging liquids containing biological materials such as nucleic acids using a general centrifuge.

Abstract: The present invention relates to a liquid dispensing and handling system for transferring and moving various liquids containing biological materials and/or the like to predetermined containers and for isolating and purifying the biological materials from the liquids in an automatic fashion according to a predetermined protocol.

Abstract: The present invention relates to a method of manufacturing a kit for isolating and purifying nucleic acids, or various biological materials, a kit manufactured by the method, and an apparatus using the kit.

Abstract: To sequence DNA automatically, fluorescently marked DNA are electrophoresed in a plurality of channels through a gel electrophoresis slab; wherein the DNA samples are resolved in accordance with the size of DNA fragments in the gel electrophoresis slab into fluorescently marked DNA bands. The separated samples are scanned photoelectrically with a laser and a sensor, wherein the laser scans with scanning light at a scanning light frequency within the absorbance spectrum of said fluorescently marked DNA samples and light is sensed at the emission frequency of the marked DNA. The light is modulated from said laser at a predetermined modulation frequency and fluorescent light emitted by said DNA bands at said modulation frequency is detected, whereby background noise from the medium through which the light is transmitted is discriminated against.
