摘要:
A biological sample holder for holding a solid phase sample, including a handle, and a seal area suitable for being received in an opening of a sample receiving chamber of a cassette, mountable to a sample analysis instrument. The holder further includes a stem connected to the seal and a sample retainer connected to the stem for retaining solids in the retainer, the sample retainer including a perforated wall region for allowing fluids to pass through the wall but preventing the solid phase sample from passing through the wall.

A controlled transfer biological sample material collection device is disclosed which comprises: a body; and a sample collection member for collecting the biological sample material (not shown), the body housing a sample storage medium for generally dry storage of the biological material, the collection member being moveable from an exposed position (shown in FIG. 8) where collection of a biological sample is possible, to a transfer position (shown in FIG. 9) which effects transfer of at least a portion of the collected sample to said medium. The device is characterized in that the body slideably supports the sample collection member, and in that the body or collection member include a ramp-like projection portion (116 FIG. 10) operable to force the collection member into the transfer position against the medium and to effect said transfer as the collection member slides within the body.

Disclosed is a biological sample holder, a container for storing multiple holders, and an automated holder retrieval system. The sample holder may comprise an elongate generally planar support including a handle end and an opposing biological sample storage end, wherein, a substrate for accepting a biological sample is mounted to the holder at said sample storage end. Optionally the substrate is so mounted within a recess in the surface of the support and the recess has a local surface providing a reaction surface for allowing a sub-sample to be removed from the medium by mechanical action, such as cutting or punching. The container may include an array of wells each well being generally square or rectangular in plan and the holders dimensioned so that they are held diagonally in a respective well. The automated biological sample storage apparatus may include a mechanical handling device, and an associated electronic control capable of controlling the mechanical handing device to pick a predetermined sample holder from an associated well, or to place a predetermined sample holder into an associated well, optionally removing or replacing a container lid where a lid is used.

A microfluidic device 100 is disclosed comprising a body 112 including a biological sample S and/or reagent R receiving slot 122. The sample and reagent are carried on a solid support 10. The device 100 includes two punch assemblies 130 for removing portions of the solid support 10 and delivering them, together with the sample and/or reagent(s), to a receiving chamber 126 for subsequent processing. The device can be used for various assays including those which require just the addition of water in the reaction chamber with no pre-treatment of sample prior delivery into the chamber.

The present invention provides a device comprising: a housing comprising a first opening for connecting to a liquid source, a second opening for connecting with an apparatus for drawing in and expelling liquid, and a valve means comprising a filter carrier and a filter, the filter carrier supporting the filter and being movable within the housing; wherein the valve means permits liquid that is drawn into the housing from the liquid source by the apparatus to enter the apparatus by bypassing the filter but which forces liquid that is subsequently pushed from the apparatus through the second opening into the housing to be filtered through the filter.

The disclosure relates to an in-hand operable compressor 200 for compressing syringeless filter devices 100. The compressor 200 includes a base 220 having a receiving well 222 adapted to receive a bottom portion of the uncompressed device 100, and a discrete top 210 having a receiving recess (212 FIG. 4) adapted to receive a top portion of the uncompressed device 100, said base and top being brought together in use by hand compression to cause compression of the device 100 located in the well and recess of the compressor. Surface formations 250 and 252 (FIG. 2) are complementary and inhibit misalignment of said well and recess during the in-hand compression.
