4.2.2 Program Line Pull Cycle Parameters
Each of the four programmable parameters in a program line is defined below:
HEAT HEAT controls the level of electrical current supplied to the filament.
The HEAT required to melt a piece of glass is a function of the filament
installed and the particular glass size and composition. It is important
that the HEAT value be set relative to the Ramp Test value as discussed
in the Operation Section. Generally, changes to HEAT will be made in
steps of about 5 units since in most cases smaller changes will have little
effect.
PULL
(Range 0-255)
This parameter controls the force of the hard pull. In general, the higher
the pull, the smaller the pipette’s tip diameter and the longer its taper.
Useful changes in PULL strength are 10 units or more to see an effect.
NOTE: A one-line program containing PULL = 0 and a low VELOCITY
setting (15 – 40), looped 2-3 times, can be used for making short patch-
type pipettes.
