GSL1000X20 Mini Tube Furnace with 20mm Quartz Tube and Vacuum Flange
The GSL1000X20 is a compact tube furnace engineered for laboratory-scale thermal processing of small samples requiring precise temperature control up to 1000°C. It is particularly suited for experiments conducted under vacuum or controlled atmospheres, such as vapor-liquid-solid (VLS) growth, chemical vapor deposition (CVD), and gas analysis. Its small footprint and flexible orientation options allow integration into gloveboxes or other confined setups.
This furnace features a 20 mm outer diameter fused quartz tube (17 mm inner diameter, 192 mm length) included with the unit, along with stainless steel vacuum flanges—one KF25 quick clamp flange and one screw-tightened flange with a 1/4″ gas inlet—enabling vacuum levels down to 20 millitorr when used with a mechanical pump. The furnace and its PID temperature controller are separable, allowing flexible installation either horizontally or vertically to accommodate various experimental setups.
Wichtigste Merkmale
- Maximum temperature of 1000°C for short durations; continuous operation up to 900°C.
- Precision PID controller with auto-tune and 30 programmable segments for heating, dwelling, and cooling cycles.
- Heating zone length of 55 mm with a constant temperature zone of approximately 20 mm ±5°C.
- Fe-Cr-Al alloy heating elements doped with molybdenum for stable and efficient heating.
- Protective shield mounted on the furnace to prevent scalding at temperatures above 800°C.
- Includes ceramic tube blocks to reduce heat radiation and optional quartz blocks for high vacuum applications.
- Compatible with 110V or 220V power supplies via included transformer; supports series connection of two furnaces at 110V.

Its compact size and vacuum compatibility make it suitable for integration into gloveboxes and other controlled environments.
Hinweise zur Konfiguration und zum Betrieb
The furnace and temperature controller are separable, allowing flexible installation either horizontally or vertically. Included are ceramic tube blocks to minimize heat radiation; quartz blocks are available optionally for enhanced vacuum sealing. The unit includes a protective shield to prevent burns at high temperatures. For vacuum operation, a mechanical pump is required but not included. The furnace supports connection of two units in series for 110 VAC operation. Replacement consumables such as quartz tubes and O-rings should be ordered separately.
