Abstract:
A device for use in the isolation of a biological material from a basic material containing said biological material and binding said biological material to a solid phase, comprisinga container for holding a mixture of the basic material and a solid phase which binds the biological material;a connector for connecting and disconnecting the container to an inlet for washing fluid and eluant fluid;a connector for connecting and disconnecting the container to an outlet for the washing fluid after washing the biological material bound to the solid phase, and a connector for connecting and disconnecting the container to an eluant reservoir for collection of the eluant fluid with the dissolved biological material;a filter which is constructed so as to allow the passage of fluid and is capable of retaining the solid phase, said filter being positioned between the container and the outlets, wherein the connector to the outlet for the washing fluid and the connector to the eluate reservoir are coupled to a shut-off element which is constructed so as to direct a fluid flow from the container either to the outlet for the washing fluid, or to the eluate reservoir; andan inlet element which can be connected to the inlet and is movable between a top position for discharging sample fluid and a bottom position for passing through washing fluid and eluant fluid.
