Pull Cable
(T in Figure 1-5)
This cable transmits the pulling force of the solenoid to the Puller
Bars via the Upper (F) and Lower Pulley Assemblies. It is made of
flexible metal with a nylon coating. Never pinch or distort the
cable. The cable is terminated with crimped-on clamps or ‘swages’
at the back-end of each Puller Bar.
Glass Stop Mounting
(U in Figure 1-5)
Holes for mounting the glass stop. Either the left side or the right
may be used.
1.5.5 Cabinet
Baseplate The top thick metal plate on which the mechanical assemblies are
mounted.
Base The Base includes the cabinet to which the top Baseplate is
mounted as well as the transformers and the circuit board
contained within.
1.5.6 Electronics
The P-1000 micropipette puller is controlled by a dsPIC microprocessor. The HEAT power
supply is a precision constant-current switching unit. The PULL supply is a constant-current
DC power supply. The velocity trip point is set by a D-A converter. The output of the velocity
transducer is compared to the output of the velocity D-A to determine when the trip velocity
is reached.
