OTF-1200X-VT-80 Split Vertical Tube Furnace with 80mm Quartz Tube, Vacuum Flanges, and 1100°C Max Temperature
The OTF-1200X-VT-80 is engineered for laboratory applications requiring precise thermal processing under vacuum or controlled gas atmospheres. Its vertical split tube design facilitates rapid sample heating and quenching, making it suitable for quenching tests and accurate temperature measurements. The furnace incorporates an 80 mm outer diameter high-purity quartz tube, which supports a maximum working temperature of 1200°C, ensuring chemical inertness and thermal stability during processing.
This model features a robust double-layer steel casing with air cooling to maintain surface temperatures below 65°C, enhancing operational safety. The heating zone is 440 mm long with a 150 mm constant temperature region controlled to ±1°C. The furnace is mounted on a heavy-duty mobile cart for convenient relocation within the laboratory environment.

Hinweise zur Konfiguration und zum Betrieb
The furnace includes vacuum flanges with integrated gauges and valves. Optional accessories include mullite tubes for higher temperature operation and advanced temperature control software packages. Users must install a two-stage pressure regulator on gas cylinders to limit pressure below 3 PSI for safe operation. The quartz tube is designed for vacuum and low-pressure use below 0.2 bar and temperatures up to 1000°C under vacuum conditions. Calibration before use is recommended to ensure temperature accuracy.
