Configuration & Operating Notes
The furnace includes a rotary quartz tube with mixing blades and flanges equipped with gas inlet/outlet fittings, needle valves, and magnetic fluid dynamic seals to maintain controlled atmospheres. An optional vacuum system with a double stage rotary vane pump is available for processes requiring reduced pressure. Temperature control software based on LabVIEW can be supplied with a dedicated laptop for programming, monitoring, and data recording. Electrical installation requires a single-phase 208–240 V power supply with a 30A breaker. Users should ensure proper ventilation and follow safety protocols when operating at high temperatures and with reactive gases.
