In one embodiment, a particle-retrieval device in accordance with the present teachings includes a receiver tube, vacuum-flow providing means and particle-disengaging means. The receiver tube is in fluid communication with the vacuum-flow providing means such that when flow is introduced into the vacuum-flow providing means, a suction or vacuum flow is developed at an end of the receiver tube. The suction causes a particle to adhere to the end of the receiver. A particle is disengaged by discontinuing the suction and, advantageously, by wetting the engaged particle.

A dryer for use with chemical compounds employs controlled vacuum, elevated temperature and dry, inert gas to dry the chemical compounds. The dryer includes a vacuum chamber into which trays containing the compounds are placed. The chamber includes heating elements which elevate the temperature of chemical samples placed within the chamber. Supplying and evacuating manifolds, each with a plurality of orifices for supplying and evacuating dry inert gas, provide a substantially laminar flow of dry inert gas just above the trays of chemical compounds which are to be dried. The laminar gas flow removes the unwanted vapor which tends to form above the tray of chemical compound, thus accelerating the drying process.
