Abstract
A system for handling hygroscopic metal halide pellets serving as fill material in high pressure metal halide lamps. The pellets are loaded into stoppered transport vials at their place of manufacture. At the place of utilization, the stoppered end of the vial is inserted into a self-sealing opening in a reservoir through which dry gas is flushed to remove any contaminants. The vial is then unstoppered without removing it from the opening and its contents spill out into the reservoir. A transfer device accommodating a set number of pellets is brought into conjunction with an outlet opening, the device is filled, and the pellets transported to their destination through a channel filled with dry gas.
