ABSTRACT:
A 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 zoom lens, or a selected one of a series of lenses, so that a beam of selected length and configuration is refracted against the glass tubing between the gripping jaws.
