An apparatus comprises a vessel having an interior chamber formed by a vessel wall. The vessel wall comprises a double-walled structure having an inner wall and an outer wall. A moveable lid is configured to form an airtight seal with the interior chamber in a closed position. A basket is positioned within the chamber. One or more vibration devices, such as transducers, are attached to the basket. A heating coil is positioned within the chamber and surrounding the basket. The heating coil is configured to heat the basket using induction heating. An airtight space is formed between the inner wall and the outer wall and is filled with a gas. The temperature within the chamber may be lowered by cooling the gas.
