OTF-1200X-PV-HVS High Vacuum Compact Tube Furnace with 1200°C Max Temperature, 8″ Heating Zone, and Integrated Turbo Vacuum System
The OTF-1200X-PV-HVS is engineered for laboratory applications requiring controlled high-temperature treatments under high vacuum conditions. It integrates a compact tube furnace capable of reaching temperatures up to 1200°C with a high-performance turbomolecular vacuum pump system. This combination allows precise thermal processing within a sealed quartz tube chamber while maintaining ultra-low pressures essential for sensitive material synthesis and heat treatments.
The heating chamber consists of a 60mm outer diameter quartz tube sealed with vacuum flanges equipped with gas inlet/outlet fittings, thermocouple feedthroughs, and a mechanical vacuum gauge. The turbopump, connected via a KF40 clamp, enables the system to achieve ultimate vacuum levels as low as 10^-6 torr at ambient temperature. Temperature control is managed by a PID programmable controller featuring auto-tuning and protection functions, supporting up to 30 programmable segments for ramping, dwelling, and cooling with ±1°C accuracy.

Typical Applications
This tube furnace system is ideal for vacuum heat treatments, material synthesis, thin film processing, and research requiring controlled atmospheres at high temperatures. It supports applications in semiconductor fabrication, ceramics, metallurgy, and advanced materials development where precise temperature control and high vacuum are critical.
Configuration & Operating Notes
The furnace includes a pair of quartz blocks to minimize heat loss from the heating zone. Crucibles for sample containment are available separately. The vacuum flange set integrates gas inlet/outlet fittings and a vacuum gauge for process monitoring. The turbomolecular pump system is compact and designed for easy connection via KF40 clamps. Optional LabVIEW software enhances temperature profile management and data acquisition. Users should ensure proper vacuum sealing and follow safety protocols for high-temperature and vacuum operation.
