Clear tubing:  Clear quartz has a much higher transmission of ir energy than does translucent tubing.  Clear quartz allows for faster response and generates a shorter wavelength than translucent.  Available in 3/8", 1/2", 5/8", 7/8", or 1" diameters.

Translucent tubing:  Translucent quartz has a longer wavelength, and non-exposed heating element.  Some applications prefer the aesthetics of a translucent tube because the heating element is concealed within the tube.  Available in 3/8", 1/2", or 5/8" diameters.

Standard-Wound:  This element is a single precision wound resistance wire made of iron-chromium-aluminum.  It typically reaches the desired temperature in 10-20 seconds and has a typical life expectancy of 10,000 hours.

Multi-Wound:  This element has tow precision wound resistance wires made of iron-chromium-aluminum wire that are inter-twined.  It typically reaches the desired temperature in 5 seconds and has a typical life expectancy of 5,000 hours.

Internal Ceramic Reflector:  This reflector is a ceramic fiber refractory material that is machined into 1/2 of the inside diameter of the tube.  This design minimizes the time and expense of replacing external reflectors over time. It is only available in 5/8" tubing.

Gold Reflector:  This reflector applies gold on one  side of the tube.  It is highly reflective and directs the infrared energy at the process.  It also eliminates the need for an external reflector.

No Reflector:  Used to replace existing tubes that have no reflectors.
