Abstract
A sample loading mechanism includes a hopper mounted to a base for positioning the hopper with respect to a furnace for releasably holding a relatively small sample in relation to a crucible used with the furnace. The hopper includes a floor with a movable element for alternately closing the floor for holding the sample and opening the floor permitting the sample to drop into the crucible. A plate is slideably mounted to the base above the hopper and includes an aperture which aligns with the hopper in a first position for admitting a sample to the hopper and is slideable to a second position for selectively sealing the upper end of the hopper. An actuator is provided for selectively controlling the movable element of the hopper for dropping the sample into a crucible aligned below the hopper.
