System and cartridge for processing a biological sample
First Claim
1. A sample processing system for processing a sample contained in a liquid, said system comprising:
- a) a pipettor having a pipette tip for dispensing liquids, and b) a cartridge comprising;
(b.1) a chamber which has an inlet and an outlet, said chamber containing a microarray device having an active surface which is formed by an array of different oligomers at known locations, said active surface being accessible to liquid contained in the chamber, (b.2) an optical interface which provides optical access to said active surface of said microarray device, and (b.3) an inlet port and an outlet port, said inlet port being so configured and dimensioned that it forms an air-tight connection with the pipette tip when said pipette tip is inserted into said inlet port.

Abstract
There is disclosed a sample processing system for processing a sample contained in a liquid. Specifically, there is disclosed a sample processing system comprising a pipettor, and a cartridge. The cartridge comprises a chamber which has an inlet and an outlet. The chamber contains a microarray device having an active surface. The active surface is accessible to liquid contained in the chamber. The cartridge further comprises an optical interface that provides optical access to the active surface of the microarray device, an inlet port and an outlet port. The inlet port is so configured and dimensioned that it forms an air-tight connection with a pipette tip when the pipette tip is inserted into the inlet port.

21. A sample processing system for processing a sample contained in a liquid, said system comprising:
-
(a) a cartridge having;
(a.1) a chamber which has an inlet and an outlet, said chamber containing a microarray device having an active surface which is formed by an array of different oligomers at known locations, said active surface being accessible to liquid contained in the chamber, (a.2) an optical interface which provides optical access to said active surface of said microarray device, and (a.3) an inlet port and an outlet port, said inlet port being so configured and dimensioned that it forms an air-tight connection with a pipette tip when said pipette tip is inserted into said inlet port;
(b) a cartridge holder adapted for holding said cartridge in such a position that the flow-cell inlet lies at a lower height than the flow-cell outlet, whereby liquid supplied to the flow-cell chamber through said inlet displaces air contained in said chamber and enables a complete and bubble free filling of said chamber with liquid, any excess of liquid leaving said chamber through said flow-cell outlet; and
(c) a waste container for receiving excess liquid flowing out of the flow-cell outlet. - View Dependent Claims (22, 23, 24, 25, 26, 27)
