ABSTRACT:
The micropipette puller of this invention includes a pair of gripping jaws that pull a length of glass tubing in opposite directions. The source of heat is a laser and a beam is directed into a beam directing means, such as a lens or mirror, to refract or reflect the beam against the glass tubing between the gripping jaws. The mirror or lens may be oscillated at various rates and through selected angles in each direction to move the reflected beam a selected amount and at selected rates along a greater length of the glass tubing.
