The present invention is directed a system for coupling a macroactuator to
a movable element of a micromachined device. The system includes a
micromachined device, a first body for holding a macroactuator, a
macroactuator mechanically mounted on the first body, a second body
having a bore for receiving the first body, a screw arrangement for
fixing the axial position of the first body within the bore of the second
body, and a plate arrangement for mounting the micromachined device on
the second body. The plate arrangement is mounted in such a way that the
macroactuator exerts a predetermined force or pressure on a movable
element of the micromachined device. The present invention further is
directed to a pipetting module that includes the micromachined device and
the macroactuator.
