Pipette puller

DETAILED DESCRIPTION The pipette puller of the invention is designed to meet all pipette, multi-barrel pipette, patch and extracellular needs.
The pipette puller of the invention incorporates a DC constant-current source that provides up to 30 amps of power, allowing use of a wide range of coil materials and sizes.
The new pipette puller is packaged in an integrated puller tower and process controller, making it easy to use and compact.
The pipette puller is user-friendly and is able to meet demanding needs.
This new pipette puller has been designed for scientists.
The superior design includes high grade aluminum and stainless steel construction, which ensures years of trouble-free operation.
The linear bearing technology gives an accurate and smooth gravity feed, pull.
The bayonet-style burning element holder eliminates the need to touch a fragile well-burned coil.
One element holder is pulled out and is replaced with another.
Heat is reset and a pipette is pulled, all without touching a coil.
Any coil can be easily centered using two knobs, which provide X-Y movement of the coil housing.
Using the side mounted coil jog knob, one can vertically position the coil accurately along a pipette or length of glass in a Z axis movement.
A two position jog can be set up for patch electrode fabrication.
The side-mounted coil jog knob eliminates the cumbersome technique of repositioning the glass between two sequential burns.
In addition, one can easily dial in the length of the first pull using the calibrated, removable side-mounted primary stop that provides reproducible pull lengths as long as ten millimeters.
Readability of the adjustment is one-fourth's of millimeters.
Patch electrode architecture is now placed under total control by the invention.
Dual heat controls provide two pre-set temperatures which are available at the push of a button.
Each control is a ten turn locking/calibrated dial for ease of use and repeatable accuracy.
Simply pushing a button selects heat 1 or heat 2.
An advisory lamp above the dial provides an alert that the heat control has been activated
