GSL1800X60 High-Temperature Vacuum and Tube Furnace with Kanthal Super-1900 MoSi2 Heating Elements
The GSL1800X60 tube furnace is engineered for precise thermal processing of material samples under vacuum or controlled gas environments, crucial for sintering and advanced material research. Its design accommodates a high-purity alumina tube with an outer diameter of 60 mm and a length of 1000 mm, enabling uniform heating within a 300 mm heating zone and a tightly controlled 100 mm constant temperature zone.
This bench-top furnace integrates Kanthal Super-1900 grade molybdenum disilicide (MoSi2) heating elements, known for their durability and high-temperature capability, supporting continuous operation up to 1750°C and short-term peaks to 1800°C. The temperature is regulated by a 30-segment programmable SCR digital controller with PID and auto-tune functions, achieving ±1°C accuracy. The furnace structure includes a double-layer steel casing with internal air cooling fans to maintain safe external temperatures.
Wichtigste Merkmale
- High-purity alumina tube (99.8% purity) with ZrO2 ceramic liner for thermal insulation and energy efficiency.
- Vacuum sealing flanges equipped with double silicone high-temperature O-rings, needle valves, and a dial vacuum gauge for immediate vacuum operation.
- Maximum power consumption of 7 kW with single-phase 220V AC input and 50/60 Hz frequency.
- Heating rate up to 5°C/min below 1600°C and 2°C/min above 1600°C for controlled thermal ramping.
- Includes four alumina foam tube blocks to minimize heat radiation loss inside the tube.
- Optional PC control module and Eurotherm 3204 temperature controller available for enhanced temperature profile management and data logging.
- Air-cooled double-layer steel casing with two internal fans to keep external temperature below 60°C.

This furnace is ideal for sintering new material samples, thermal treatments, and research experiments requiring controlled atmospheres and high vacuum conditions. It supports processes in material science, chemistry, ceramics, and semiconductor research where precise temperature control and vacuum integrity are critical.
Hinweise zur Konfiguration und zum Betrieb
The standard package includes the alumina tube, vacuum flanges with valves and gauge, Kanthal Super-1900 heating elements, alumina foam tube blocks, and a B-type thermocouple. Optional accessories include a PC control module with software, Eurotherm 3204 temperature controller, digital vacuum gauges, and various vacuum flange fittings to enhance vacuum performance.
Users should perform temperature calibration before operation to ensure accuracy. The furnace is designed for vacuum and low-pressure gas use below 0.02 MPa. Graphite crucibles should not be used inside the alumina tube. Gas flow rates must be limited to under 200 SCCM to maintain system integrity.
