ABSTRACT:
A pipette puller has a heater coil X-Y position controlled by two knobs. The coil can be vertically positioned along a pipette by moving a third knob for the Z positioning. A dual-heat heat control provides two pre-set temperatures. A movable shield covers the coils when they are heated, eliminating accidental burnings. Sensors run the status panel. The panel tells when to start a pull, the position of the movable chuck, the position of the shield, and when to reposition the coil and indicates a primary stop between two burns of a patch electrode pull. A vertical rail supports all of the major mechanical moving parts, with the exception of the adjustable stop which swings in and out of operative position.
