The Coarse Control Lever moves the end of the micropipette through a
maximum of 4mm in the x-y plane for coarse positioning of the pipette.
The Fine Control Lever moves the pipette through a maximum of 0.75mm
in the x and y planes, and is used for accurate positioning of tools and
specimens for all normal procedures.
On each control the movement of the pipette exactly follows the
movement of the control lever. So, for example, moving a lever to the
left will move the pipette to the left.
The Fine Control Lever also provides Z movement of up to 5mm by the
rotation of the lever.
Petri Dish Positioning
Stage movement is controlled by the X and Y controls as described on the
previous page. The stage will move a maximum of 40mm in each direction
ie 20mm from the centre position. This allows viewing of a specimen
within the area of a Petri dish that is accessible to micropipettes.

Petri Dish Choice
For most applications, we recommend plastic Petri dishes that are
certified for use in ART clinics, which have a diameter of 50 to 60mm. A
dish with a low wall height may be preferable to allow the maximum area
of the dish to be accessible by the pipettes.
