The Vacuum Degassing Oven (VDO) is used to precisely and accurately degas pressure-aged binder samples to meet AASHTO R28-06 and ASTM D6521-05 standards.

The compact, table-top unit is constructed of stainless steel with a hinged lid to conserve space while allowing easy access to the stainless steel vacuum chamber.

The oven holds up to (4) specimen containers and features a self-contained, automatic vacuum system. The high-precision controller features a digital display indicating time, temperature and the current stage of each process, as well as illuminated pre-heat, degas and end/stop buttons. It also features audible and visual alarms, indicating end of process. Over temperature protection is provided by a pressure safety release solenoid valve.
