Embodiment Construction

[0070] Figure 1 shows a device 1 comprising an upper part 2 comprising a series of ridges 3 and protrusions 4 which adapt the device 1 to be detachably tested by an instrument (not shown) The grab arm remains. The lower part 5 is snap-fitted on the base of the upper part 2 .

[0071] The lower part 5 is provided with a plurality of vertically arranged openings 6 which allow liquid access to the reagent beads 7 contained therein.

[0072] Reagent beads 7 are added to the lower part 5 before it is mounted on the upper part 2 . The size of the opening is such that the reagent beads 7 cannot fall from the lower part 2 during movement of the device.

[0073] Thus, simply mounting the upper part 2 to the gripper arm of the detection instrument, and thereby allowing the device to be moved as desired, allows easy and reliable transfer of the reagent beads 7 from one reagent container to another within the instrument.

[0074] When the lower part 5 is immersed in the liquid in the r...

Abstract

A device for transferring reagents in solid or liquid form from one place to another on an apparatus, said device comprising an upper portion, adapted to be held, and a lower portion adapted to hold reagents in solid or liquid form, in an available manner. For example, the reagents may be held within a cage structure or retained on an outer surface of the lower portion. Methods for using the device, as well as apparatus for use in conjunction with the device are also described and claimed.

Description

technical field [0001] The present invention relates to devices for mobilizing reagents used in chemical and biochemical assays and methods of using these devices. Background technique [0002] During the performance of chemical or biochemical assays it is often necessary to transfer small amounts of reagents in solid or liquid form from one vessel to another. Increasingly, these assays are performed using automated processes and procedures, thus requiring automated devices that can pick up and transfer large quantities of reagents. [0003] Examples of specific reagents that can be used in solid form are those necessary to carry out amplification reactions, especially the polymerase chain reaction (or PCR). PCR ready-to-go beads for performing DNA amplification are commercially available, such as those sold by Amersham BioSciences, UK. [0004] They contain all the components necessary to perform standard PCR, including buffer reagents, salts or polymerase in lyophilized ...
