Abstract
This invention provides improved components (e.g. array “pins”, print head, substrate platen, print head platen, and the like) for microarray printing devices as well as microarray printing devices incorporating such components. In one embodiment, this invention provides a microarray print head comprising a plurality of glass or quartz spotting capillaries disposed in a support that maintains a fixed spacing between the spotting capillaries and that permits the spotting capillaries to move in a direction parallel to the long axis of the capillaries.
Claims13
A microarray print head, said print head comprising:
- a plurality of glass or quartz spotting capillary tubes disposed in a support that maintains a fixed spacing between said spotting capillaries and that permits the spotting capillary tubes to move in a direction parallel to the long axis of said capillary tubes, wherein said capillary tubes:
- have an internal diameter ranging from about 20 μm to about 100 μm;
- have an aperture ID or OD ranging from about 20 μm to about 75 μm;
- have an outside diameter ranging from about 0.4 mm to about 1 mm;
- have a center-to-center spacing ranging from about 1 mm to about 10 mm;
- have a load volume ranging from about 0.05 μL to about 1 μL;
- and
- range in number from about 2 to 256;
- wherein said capillary tubes are in fluid communication with a manifold.
