These quartz pencil lamps are small, low-pressure, mercury-vapor discharge lamps made of double-bore material with both electrodes at one end. They are very stable lamps and maintain a high output of ultraviolet radiation. They have a spectral emission consisting of many well-separated lines in the ultraviolet and visible portions of the spectrum. They are widely used as spectral calibration sources in spectroscopy, chromatography, and photometry.
Note: A 24" cord set with plug is provided for attachment to the Power Supply. Power supply (#70-298) is not included and sold separately. The UV Light Shields (compatible with #40-759) are sold separately.
Separately-housed power supply for efficient operation of the UV pencil lamps above. Dimensions are 4.5" L x 4" W x 3.13" H. The net weight is 5 lbs. The metal housing is provided with an on/off switch, rubber feet, a 7.5 ft power cord, and a 3 ft secondary lamp cord.
Shield A has a 1mm inner diameter drilled hole. Shield B has a 7.9mm x 15.9mm aperture, and Shield C has a 4.8mm x 38.2mm aperture.
