Coupling for use with micromanipulator
 The coupling of the present invention is adapted for use with a micromanipulator and a pair of pipettes. The micromanipulator comprises a pair of elongated arms and linkage connected to the arms for moving the arms in a plurality of directions. The coupling includes a housing having an arm receptacle at one end and a pipette holding device at the opposite end. A ball and socket swivel is provided within the housing and comprises a movable socket member which is matingly engaged with a spherical ball. The ball is connected to the pipette holding device. A threaded bolt engages the movable socket member and is adapted to cam the socket member into frictional engagement with the ball so as to lock the ball and socket joint against movement.
