Abstract: This disclosure relates to a device for the uptake of capsule parts. The device may include a female member having an internal cavity defined by a contact surface which engages the outer surface of the capsule, or a male member having an outer contact surface which engages the inner surface of the capsule. In each embodiment of the invention the device includes at least one channel opening into the contact surface thereof for supplying a source of underpressure or overpressure to the capsule. The underpressure creates a suction which facilitates the uptake and holding of the capsule, while the overpressure ejects the capsule from the device.
