Abstract
The method of the present invention consists of the steps of heating an area along the length of a small diameter glass tube while the tube is being rotated, pulling the heated tube using an unidirectional force to rapidly extend the heated area while mechanically maintaining the heat source centrally located along the portion of the tubing being extended. The extended tubing is subsequently cooled and separated at the narrowed portion to produce two capillary tubes.
