Even
longer and thinner microelectrodes that cannot be
produced from glass capillaries (1/1.2/1.5mm) can be
produced with the PE-22. Multibarreled electrodes are
also producible.
In
nerve center experiments where microelectrodes are
inserted deep into the brain, parallelism is essential
to a long tapered tip. To achieve parallelism required,
the adjustable range of the microswitch has been
increased. As compared to conventional models, the
PE-22 is capable of producing microelectrodes of more
different shapes. The microswitch is now calibrated
and thus easy to adjust, which contributes to improved
reproducibility.
To
enhance the safety, a metal cover is attached to the
heater unit and the shaft. Through the use of a fall
under its own weight and magnets, glass capillaries
are pulled vertically. The device that holds a glass
capillary employs a drill chuck system that accepts ø2
- 6mm glass capillaries. Moreover, using a bundle of
ø1mm glass capillaries, multibarreled microelectrodes
can be produced. Magnet and heater level adjustments
are performed easily through the digital display and
thus reproducibility has improved.

In the event of using glass capillaries of ø4mm or
larger, there is a limit to the wall thickness and
length of a glass capillary. Please contact SPT for
details.
