Our dual stage EP-450 pipette puller
uses several unique methods to make consistent electrodes pull
after pull. The theory of operation is based on time management
and millivolt control of the element for both first and
second pulls. By controlling the time, or at least establishing
a time basis, the user can create a pipette shape and length
consistently and repeatedly. The EP-450 has been designed to
be multi-user friendly. A simple data log book is included
to record electrode glass type, electrode glass diameter, first
pull time, first pull voltage, second pull time and second
pull voltage.
Using this information, any user can easily reestablish
their settings and recreate a specific electrode shape. The
EP-450 has a unique ergonomic design. It is comfortable for
the user to operate on a daily basis. It has been constructed
for easy access to the loading mechanism, which eliminates
operator bending and kneeling. All controls are set at a
45° angle for comfortable viewing. A fine pitch 100TPI
pipette stop adjustment screw makes it very easy to balance
the upper and lower electrodes to ensure symmetric electrode
lengths every pull. The filament carriage travels from the
first pull location to the second pull location and has a
micrometer dial read-out for fine adjustment. The carriage
also has a simple heat shield that uses a standard 25mm x
75mm microscope slide to protect the element during the pull
process.
