- • The furnace ca be modified into a HPCVD ( hybrid physical-chemical vapor deposition ) furnace
via DIY a sample susceptor ( click picture below-left to see how ) - • The furnace can be used for brazing of two flat < 1"diameter sample via top dead weight under
vacuum at <1000° ( click picture below -right to see how )

|
• The tube furnaces with quartz tube are designed for using under vacuum and low pressure
<0.2 bar / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°C.
The flow rate for gases should be limited to < 200 SCCM (or 200ml/min) for reducing thermal
shocks to the tube.- • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit
the pressure to below 3 PSI for safe operation.
