摘要：A method for washing and vacuum drying long necked laboratory flasks. Theapparatus includes a cabinet which presents a washing and drying compartment and apump and rotary spray arm. A special rack which can be rolled into and out of thecompartment includes a central manifold and a plurality of distribution arms extendingradially from the manifold. Upright spindle tubes extend from the distribution arms toreceive the inverted flasks such at that the tubes extend through the narrow necks of theflasks with the open ends of the tubes located within the bodies of the flasks. Adiaphragm coupling allows water to be pumped to the manifold for delivery to thespindle tubes during washing and rinsing cycles. The tubes spray the water directly insideof the flask bodies for thorough washing and rinsing. A vacuum conduit extending fromthe manifold carries a seat which engages a gasket to couple the manifold with a vacuumblower when the rack is moved into the cabinet. During the drying cycle, the blowerapplies vacuum through the manifold to the spindle tubes to draw moist air out of theflasks and replace said moist air with drier air from the compartment. The vacuum dryingsystem recirculates and heats the air and mixes said air with dry outside air for enhanceddrying of the flasks.
