ABSTRACT:
A sealable lid assembly for a vacuum distillation apparatus has a lid pivotally and telescopically mounted to the vacuum distillation apparatus. Spaced-apart wheels are rotatably mounted to the lid. Tracks are disposed on the vacuum distillation apparatus in a position to engage the wheels and raise the lid vertically above a manhole of the vacuum distillation apparatus upon pivotal movement of the lid, which is initiated by nominal physical exertion of a single operator. Extending outwardly from and adjacent the manhole is a flange. The flange has a channel to receive a gasket. A protrusion extends outwardly from a bottom of the lid in a position to extend into the channel and sealably engage the gasket when the wheels disengage the tracts. Clamp assemblies are provided to releasably engage the lid with the flange and draw the protrusion into sealable, releasable engagement with the gasket. The gasket can be an endless type or non-endless type with obtuse faces oppositely and matingly positioned adjacent one another in the channel. A handle extends outwardly from the lid to assist the operator in pivotally moving the lid.
