PerkinElmer HGA Contact Cylinders for HGA 500, 400 Graphite Furnaces. 5 Sets - B0180363

HGA Contact Cylinders for HGA 500, 400 Graphite Furnaces. 5 Sets. The graphite contact cylinders used in the HGA Graphite Furnace Assembly have a special fit. Electrical resistances at the contact faces, which might affect the analytical performance, are thus reduced to a minimum. Interface from metal to graphite remains cold, due to efficient cooling. The graphite contacts are shaped to completely encase the graphite tube, placing the tube in a defined environment for uniform radiation conditions. Includes LH Contact, RH Contact, and Shield Ring.
