Mini Tube Furnace

Description

Introduction:

This series of single-zone tube furnaces is a general-purpose high-temperature heat treatment equipment for laboratories. It uses a high-purity quartz tube as the working tube, combined with a closed furnace chamber structure and high-quality resistance heating wire, achieving stable heating up to 1200℃. The equipment integrates a precise temperature control system, a double-layer air-cooled shell, and multiple atmosphere interfaces, meeting various process requirements from basic material annealing to complex atmosphere protection.

Core Structure:

• Furnace Chamber: Made of high-purity alumina ceramic fiber material, offering excellent insulation performance and low heat loss.
• Heating Element: High-quality Fe-Cr-Al resistance wire (molybdenum-doped), distributed around the furnace chamber to ensure uniform temperature.
• Temperature Control System: 30-segment programmable PID controller, temperature control accuracy ±1℃, with over-temperature alarm and thermocouple breakage protection functions.
• Furnace Tube: High-purity quartz tube (corundum tube optional), standard dimensions: outer diameter 50/60/80mm, length 600-1200mm.
• Sealing flange: Stainless steel quick-sealing flange with gas inlet/outlet, pressure gauge, and valve, supporting vacuum/atmosphere environments.

Optional configurations: Vacuum system (mechanical pump/molecular pump), multi-channel gas mixing system, remote computer monitoring interface, etc.

Features

1. Excellent dynamic sealing system can vacuum and ventilate the atmosphere. The furnace tube and the flange are extruded and sealed with a silicone O-ring, which is easy to remove and has strong sealing performance. It can be evacuated and filled with pr.
2. Temperature control accuracy can reach ±1℃. The temperature control system adopts PID method and can set 30-stage temperature rising and cooling programs. The temperature control accuracy can reach ±1℃.
3. The furnace tube is made of high-purity quartz glass material, which has extremely low thermal expansion coefficient, high temperature resistance, good chemical stability and good electrical insulation.
4. At the same time, we can customize different temperatures, styles and control methods specifically for customers. Welcome to inquire.
5. Vacuum/Atmosphere Dual-Use. Supports vacuum (≤10⁻¹ Pa) and inert/reducing/oxidizing atmospheres.
6. Comprehensive safety protection. Over-temperature, over-current, thermocouple disconnection alarms and automatic power-off.
