Clean Vacuum

The vacuum chamber is a heat resistance, Cylindrical Pyrex with 300 mm OD and 200 mm H. The system is fitted with an internally mounted 90 L/s turbomolecular pump, backed by a two-stage rotary pump which introduces clean vacuum without oil contamination that is normally present with an ordinary diffusion pump.
