1. 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 μ
m to about 100 μ
m;
have an aperture ID or OD ranging from about 20 μ
m to about 75 μ
m;
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 μ
L to about 1 μ
L; and
range in number from about 2 to 256;
wherein said capillary tubes are in fluid communication with a manifold.
