A pin holder (600, 700) for a microarraying apparatus (100) comprising at least one group of bodies of circular cross-section (660, 661, 760) packed together to form a network of pathways (810, 820) in gaps between the bodies; and an array of pins (670) slidably arranged in the pathways. The pins are held in parallel to each other automatically as a result of the self organized packing of the circular cross-section bodies, which may be spheres, for example ball bearings, or cylindrical, for example needle roller bearings. The pin holder provides for very accurate parallel alignment of the pins, low pin friction, as well as low cost and complexity of manufacture. <IMAGE> |
