PRODUCT PARAMETERS
Description
1200℃ Single-Zone High-Vacuum Tube Furnace
The 1200℃ single-zone high-vacuum tube furnace is an experimental high-temperature heat treatment device integrating high vacuum, atmosphere protection, and precise temperature control. The entire unit adopts an integrated design of the control system and furnace body. The furnace chamber is made of vacuum-formed high-purity alumina lightweight material, combined with a high-temperature alloy resistance wire heating system, enabling a stable high-temperature vacuum/atmosphere experimental environment.
The equipment has a maximum operating temperature of 1200℃ and a maximum vacuum level of 10⁻³ Pa. It supports the introduction of various gases (nitrogen, argon, hydrogen, oxygen, etc.) and is widely used in sintering, annealing, diffusion, and chemical reaction experiments in university research, materials development, and industrial testing.
Product Features
- High Vacuum Level 10⁻³Pa, Dual-Use Vacuum and Atmosphere Furnaces
Utilizes a mechanical pump + molecular pump unit, achieving a vacuum level ≤10⁻³Pa. Pure titanium metal flange seal (double rubber rings) provides excellent sealing performance. Can accommodate various gases such as oxygen, nitrogen, argon, and hydrogen, meeting the dual process requirements of vacuum sintering and atmosphere protection.
- High-Purity Quartz Glass Furnace Tube, Transparent and Temperature-Resistant
The furnace tube is made of high-purity quartz glass (SiO₂≥99.9%), with a diameter of 150mm and a length of 950mm, providing an effective heating zone of 300mm. The high transparency of the quartz tube facilitates observation of sample conditions, while the high-purity material prevents sample contamination.
- Hinged Furnace Chamber for Convenient Loading and Unloading
The furnace chamber features an upper and lower hinged opening structure, allowing for easy opening of the furnace chamber to replace the furnace tube and load/unload samples. Compared to traditional fixed tube furnaces, the openable design significantly improves operational convenience and equipment maintenance efficiency.
- Precise Gas Flow Control with Mass Flow Meters and Pressure Protection System
Equipped with two 0-300 ml/min mass flow meters for precise gas flow control. The pressure protection system uses signals from an electrical contact pressure gauge or pressure sensor to drive the control module to close the electromagnetic inlet valve, activate the electromagnetic exhaust valve and alarm, preventing excessive furnace tube pressure and potential hazards.
- 50-Segment Programmable Temperature Control with Multiple Interfaces
The programmable curve segments can be set to one group of 50 segments, two groups of 24 segments, or three groups of 16 segments. It features 30-segment programmable control (customizable), enabling arbitrary slope temperature rise and fall control, and includes programmable commands such as jump (cycle), run, pause, and stop. It is equipped with multiple computer interfaces including RS485, RS232, and USB.
