Abstract

PURPOSE:To manufacture an inexpensive nozzle with a desired inner diameter and smooth inner face by contracting a tube under tension and heating to make the tube funnel shaped and cutting the tube at the sections that have the desired inner diameter. CONSTITUTION:Tension T is applied to both ends of a hard glass tube 1 of internal diameter 1-3mm. phi and outer diameter 3-6mm. phi, and at the same time its central part is heated by a heater H. When the temperature of the heated part rises over its softening point, it is deformed and its diameter contracts. After the tube has cooled, the part that contracted in a funnel shape and has a desired diameter is cut at (a) and (b) to obtain a nozzle 2. In order to augment the mechanical strength of the nozzle 2, a reinforcing material 3 such as hydrophobic resin can be provided.
