   Applications and Industry       
   Your choices are...         
   Biological       The orifice is designed for use in biological instrumentation applications. 
   Burners       The orifice is designed for use in a burner.  Most atmospheric burners have a gas orifice that is accurately fixed in the burner throat providing air inspiration. The hole in the orifice is necessarily small to provide the correct gas flow and to provide sufficient velocity to ensure there is suction available for the correct air inspiration. 
   EDM Wire Guides       The orifice is designed for use in EDM wire guides. 
   Flow Measurement       The orifice is used for flow measurement applications including flow meters. 
   Ink Jet Printing       The orifice is used in ink jet printing applications. Current ink jet print heads utilize 20-micron diameter orifices and printer manufacturers are in the process of reducing that to 10 micron. 
   Medical       The orifice is for use in medical instrumentation applications. 
   Nozzles       The orifice is designed for use in a nozzle for flow control. 
   Particle Counters       Orifices are used in particle counting as an inactive flow control method.  Inactive methods utilize a fixed restriction and rely on a constant pressure, temperature and viscosity 
   Pneumatic Control       The orifice is designed for use in pneumatic control applications. 
   Snubber       An orifice with some provision for pressure shock absorption or dampening.  These are used in applications such as connection gauges or other instrumentation to pressure or process lines.
