We are an authorized Chromalox distributor. A coiled tungsten resistor is supported by round tantalum spacers which center the resistor in a quartz sheath. Filament is sealed into each end of the sheath.
Sheath is exhausted and filled with inert gas.
White cotton gloves should be worn when handling quartz elements. Never touch elements with bare hands because oils and contaminants from the skin could be deposited upon the quartz sheath and would cause hot spots and possibly premature failure. All other models must only be used in horizontal position. Other Chromalox products are available upon request.
