Device for receiving a chip shaped carrier and process for assembling a plurality of such devices
First Claim
1. A device for receiving a chip shaped carrier having on one side a first surface which includes an active surface coated with an array of DNA snippets or the like, a second surface on a second side opposite to said first side, and an edge having a peripheral outer surface which extends between said first and said second surface, said active surface being adapted to be read by an electro-optical reading device, said device comprising(a) a cartridge having an opening for introducing a liquid sample into said cartridge, (b) said cartridge having a casing part which has an inner surface and an outer surface, a first cavity for receiving a chip shaped carrier, (c) a layer of a sealing material which is reversibly transformable at least once from a solid state into a fluid state and which is provided in a sufficient amount to establish a liquid-tight bond between the inner surface of side walls of the first cavity and said peripheral outer surface of the edge of the chip shaped carrier when the latter is placed into said first cavity.

Abstract
A device for receiving a chip shaped carrier having an active surface, e.g. a surface which carries an array of DNA oligonucleids and which is adapted to be read by an electro-optical reading device. The device comprises: a cartridge having an opening for receiving a liquid sample and including casing parts (14, 15); a casing part having an inner surface and outer surface, a first cavity for receiving a chip shaped carrier, and means which provide access to that first cavity and thereby to the active surface of the chip shaped carrier; a sealing material which is at least once reversibly liquidifiable; the shape and dimensions of first cavity, chip shaped carrier, and sealing material, being chosen that the chip shaped carrier fits into the space delimited by the sealing material. The process for mounting the carrier in the cartridge essentially consists in placing the carrier in the first cavity and liquidifying the sealing material. In the liquid state, the sealing material closes any gap between the side walls of the first cavity and the carrier, and after solidification, the sealing material constitutes a strong and liquid-tight bond.

17. A system for carrying out evaluation and/or monitoring methods involving electro-optical reading of an active surface of a chip shaped carrier, said system comprising
(a) a cartridge having an opening for introducing a liquid sample into said cartridge, and a casing part, (a.1) said casing part being comprised in the cartridge and having an outer surface and an inner surface, a first cavity for receiving a chip shaped carrier, and means which provide access to a first cavity and thereby to said active surface of said chip shaped carrier, and (a.2) said first cavity having a flat bottom surface and side wall surfaces which extend between said outer surface of said casing part and said bottom surface; -
(b) a sealing material being provided in said first cavity, said sealing material consisting of an at least once reversibly liquidifiable material, and (c) a chip shaped carrier having an active surface which is adapted to be read by an electro-optical reading device, said chip shaped carrier being positioned in said first cavity of said casing part, and the sealing material filling the gap between the cavity walls, particularly its side walls, and the chip shaped carrier in order to hold the chip shaped carrier firmly and fluid-tightly in the cavity. - View Dependent Claims (18)
