GSL-1700X-PRY-UL-LD High-Temperature Tube Furnace with Precision Vacuum Pressure Regulation
The GSL-1700X-PRY-UL-LD is engineered for laboratory applications requiring precise thermal processing of materials under vacuum or controlled gas environments. It is particularly suited for sintering new material samples where high temperature and vacuum stability are critical. This tube furnace integrates a high-purity alumina tube with advanced MoSi2 heating elements to reach temperatures up to 1700°C, enabling short-term high-temperature treatments and continuous operation up to 1600°C.
Vacuum conditions are maintained by a sophisticated system featuring a diaphragm pump and a motorized valve with integrated electronics for precise pressure regulation down to 10^-4 torr. The motorized valve dynamically adjusts gas flow to stabilize vacuum pressure, ensuring consistent processing conditions. The furnace temperature is managed by a 30-segment programmable SCR power controller with PID auto-tuning and thermocouple protection, delivering ±1°C accuracy and programmable heating/cooling profiles.
Wichtigste Merkmale
- Maximum temperature of 1700°C with MoSi2 heating elements and alumina tube options (82mm or 101mm outer diameter).

Typische Anwendungsbereiche
Ideal for sintering and heat treatment of advanced ceramics, metals, and composite materials under vacuum or controlled atmospheres. Used in materials science research, chemical synthesis, and development of new material samples requiring precise temperature and vacuum control.
Hinweise zur Konfiguration und zum Betrieb
Optional upgrades include advanced temperature control software (MTS02-Y) and Eurotherm 3504 controller compatible with LabVIEW for enhanced programming and monitoring. The furnace must not be operated under high vacuum conditions above 1500°C to avoid damage. A two-stage pressure regulator is required on gas cylinders to limit pressure below 3 PSI for safe operation. Gas flow rates should be limited to below 200 SCCM. Continuous monitoring of chamber pressure is essential to prevent overpressure damage. The system includes safety features such as overcurrent and overheating protection for pumps and temperature control.
