12. Connect the stainless holder rod to the µ-manifold. The end of the holder rod is
a male luer fitting. It can be pressed into the center hole of the µ-manifold for a
secure hold. Fix the holder to a micromanipulator.
TIP
: We recommend WPI’s
KITE-L
for this purpose. It has sufficient precision for
the perfusion tip and an economical price. It has a left hand scale for placing on
the left side of the microscope, leaving the right side free for the patch pipette.
13. Connect the
MPS-4
to a computer USB port.
14. Connect a cable with a BNC plug to the socket on the back panel of
MPS-4
controller corresponding to the channel to be controlled. Connect the other end
of the cable to the equipment that generates the control signal.
