Abstract

A suction device for a matrix array of pipette tips includes a tray configured to hold a liquid dispensed by the pipette tips. The tray includes an open-pore tray bottom. A suction tray cooperates with the open-pore tray bottom so as to form a vacuum chamber with the open-pore tray bottom forming a constituent of the vacuum chamber. A suction element is indirectly connected to the tray via the vacuum chamber so as to be configured to actively draw liquid over an entire surface into the vacuum chamber by suction via the tray bottom.

Claims

1. A suction device for a matrix array of pipette tips, the suction device comprising:

a tray configured to hold a liquid dispensed by the pipette tips and including an open-pore tray bottom;

a suction tray cooperating with the tray bottom so as to form a vacuum chamber, and

a suction element indirectly connected to the tray via the vacuum chamber so as to be configured to actively draw liquid over an entire surface into the vacuum chamber by suction via the tray bottom.

2. The suction device recited in claim 1, further comprising a mount including an interrupted contact surface, the mount being disposed underneath the tray bottom so as to facilitate the formation of drops in the vacuum cleaner.

3. The suction device recited in claim 1, further comprising a hydrophilic pad disposed on the tray bottom so as to allow passive suction by capillary forces of the pad.

4. The suction device recited in claim 2, further comprising a hydrophilic pad disposed on the tray bottom so as to allow passive suction by capillary forces of the pad.

5. The suction device recited in claim 3, further comprising a baseplate configured to position the suction device in a defined space of a carriage of a transport device, the baseplate being connection to the suction tray by spring legs so as to prevent excessive compression of the pad, which reduces capillary force and permeability of the pad.

6. The suction device recited in claim 4, further comprising a baseplate configured to position the suction device in a defined space of a carriage of a transport device, the baseplate being connection to the suction tray by spring legs so as to prevent excessive compression of the pad, which reduces capillary force and permeability of the pad.

7. The suction device recited in claim 1, wherein the tray includes an inlet disposed above the tray bottom so as to form a washing tray.

8. The suction device recited in claim 2, wherein the tray includes an inlet disposed above the tray bottom so as to form a washing tray.

9. The suction device recited in claim 3, wherein the tray includes an inlet disposed above the tray bottom so as to form a washing tray.

10. The suction device recited in claim 5, wherein the tray includes an inlet disposed above the tray bottom so as to form a washing tray.

11. The suction device recited in claim 1, further comprising a baseplate connected to the suction tray by four soft spring legs so as to ensure that they tray bottom is disposable parallel to ends of the pipette tips.

12. The suction device recited in claim 2, further comprising a baseplate connected to the suction tray by four soft spring legs so as to ensure that they tray bottom is disposable parallel to ends of the pipette tips.

13. The suction device recited in claim 3, further comprising a baseplate connected to the suction tray by four soft spring legs so as to ensure that they tray bottom is disposable parallel to ends of the pipette tips.

14. The suction device recited in claim 5, wherein the spring legs include four soft spring legs so as to ensure that they tray bottom is disposable parallel to ends of the pipette tips.

15. The suction device recited in claim 7, further comprising a baseplate connected to the suction tray by four soft spring legs so as to ensure that they tray bottom is disposable parallel to ends of the pipette tips.
