Patent ID: 6908759

Claim:
A method of manufacturing a kit for isolating nucleic acids or biological materials from biological samples using solid materials, comprising the steps of: fabricating a container including a plurality of chambers that are configured to contain the solid materials and buffers suitable for isolation of the nucleic acids or biological materials; fabricating a cover including a protruded portion through which a bore is formed and which can dip into each of the chambers of the container, thereby allowing a magnetic bar to pick up the solid materials through the bore; filling the chambers with the solid materials and buffers for isolation of the nucleic acids or biological materials in a predetermined sequence; sealing the container with a predetermined sealing material; and packaging the cover and the container with a separate case, wherein the container is composed of inner and outer walls, a bottom plate and a plurality of partitions, and each of the chambers is defined by the inner and outer walls, the bottom plate and the two adjacent partitions; and wherein the cover further includes a flat base plate and a central shaft configured to be fitted into a central hole which is defined by the inner wall of the container, and the central shaft is guided into and supported by the central hole such that the cover can be moved upwardly and downwardly with respect to the container.
