Abstract

Disclosed herein is a device for multianalyte detection, and systems and methods for drying reagents in wells in the device in a manner that preserves functional performance. Specifically, disclosed is a system for drying reagents in the wells of a multiwell plate. The multiwell plate is sprayed with air from nozzles positioned above the multiwell plate. Air is exhausted evenly below the multiwell plate. This allows for the rapid, consistent drying of large volumes of liquid in the well of a multiwell plate.

Claims (20)

1. A system for drying reagents in a multiwell plate, the system comprising: a dry tunnel comprising at least one drying zone, the drying zone comprising at least one blower, an exhaust flow controller, the exhaust flow controller in an air flow chamber, the air flow chamber below the drying zone and above an exhaust chamber, the exhaust chamber comprising an exhauster; wherein the exhaust flow controller comprises a plurality of windows and a plurality of window covers configured to unevenly draw air out of the exhaust chamber and evenly out of the air flow chamber.

2. The system of claim 1 , wherein the exhaust flow controller comprises an array of air flow windows and air flow window covers.

3. The system of claim 2 , wherein the air flow window covers from a first plurality of air flow windows positioned directly above the exhauster are closed.

4. The system of claim 3 , wherein the air flow window covers for a second plurality of air flow windows not positioned directly above the exhauster are open.

5. The system of claim 4 , wherein the air flow window covers for a third plurality of air flow windows not positioned directly above the exhauster are partially open.

6. The system of claim 2 , wherein the at least one blower is positioned above a well of a multiwell plate to blow air down into the well of the multiwell plate.

7. The system of claim 2 , wherein the at least one blower is positioned to shower air down over the entire surface of the multi well plate.

8. The system of claim 2 , wherein the at least one blower is a plurality of blowers arranged in a grid to blow air down over the entire surface of the multiwell plate.

9. A system for drying reagents in a multiwell plate, the system comprising: the system of claim 1 having a multiwell plate positioned therein, the multiwell plate comprising a top plate with a first hole in the top plate that is not directly aligned over a first well in the multiwell plate, the dry tunnel comprising a first blower, the first blower not directly aligned over the first hole in the top plate.

10. The system of claim 9 , the multiwell plate further comprising a second well and no blower arranged over the second well.

11. The system of claim 9 , the first blower further comprising a first diameter and the first hole having a second diameter wherein the first diameter and second diameter are different.

12. The system of claim 9 , the multiwell plate in a multiwell plate alignment plate.

13. The system of claim 12 , the multiwell plate alignment plate or multiwell plate is positioned on a conveyer belt, the conveyer belt being asymmetrically shaped to facilitate only one insertion orientation of the multiwell plate alignment plate or the multiwell plate on the conveyer belt.

14. The system of claim 10 , the first hole in the top plate further comprising an axis, the axis not perpendicular to a surface of the multiwell plate.

15. A system for drying reagents in a multiwell plate, the system comprising:

a dry tunnel with a multiwell plate positioned therein, the dry tunnel comprising at least one drying zone having a plurality of blowers, an exhaust flow controller, and an exhauster.

16. The system of claim 15 , the multiwell plate further comprising a load well attached to a read well and each blower in the plurality of blowers is indexed over a load well and not a read well.

17. The system of claim 16 , wherein the reagents are dried in the load well and not the read well.

18. The system of claim 16 , wherein the load well comprises a load well floor that is not flat.

19. The system of claim 15 , wherein the load well comprises a first chamber sidewall with a first shape and a second chamber sidewall with a second shape wherein the first shape and second shape are different.
