A compact capillary dispenser has been designed that reliably stores f
ragile glass capillaries in a known orientation and positively inserts
one on demand into a robotic gripper head. A unique feature of the de
sign keeps the capillaries from jamming. A successful prototype was bu
ilt that stores 3800, 5 mu L glass capillaries (55 mm length, 838 mu m
outside diameter) in an 8 cm cube, excluding the space required for t
wo small pneumatic cylinders. The fundamental design of this dispenser
can be scaled to dispense virtually any size round cylindrical object
