Key Features & Advantages of KINTEK's Tube Furnace
- Compact & Versatile Design: Optimized for a small footprint without compromising on functionality, making it suitable for diverse laboratory environments and a wide range of applications, including high-temperature pyrolysis and composition analysis.
- Enhanced Safety & Efficiency: Features a double furnace shell design with forced air cooling, ensuring a low surface temperature for operator safety and improved energy efficiency.
- Precise Temperature Management: Equipped with PID programmable temperature control for exceptional accuracy and stable heating. Supports remote monitoring and centralized control for streamlined operations. The KT-TF17 Pro model features a user-friendly 7-inch TFT touch screen for intuitive program setting, historical data analysis, and storage for multiple program recipes.
- Durable High-Purity Alumina Tube: Utilizes a high-purity alumina tube (Al2O3) offering excellent resistance to acids and alkalis, withstands high working temperatures (up to 1700°C), ensures minimal sample contamination, and provides a long service life for a better return on investment. Note: Alumina tubes are subject to thermal shock; smaller diameter tubes generally perform better in this regard.
- Robust Vacuum Capability: Includes stainless steel vacuum flanges with various adapting ports, ensuring excellent sealing for high vacuum pressure applications (rated up to 0.001Pa) and compatibility with different vacuum pump setups.
- Flexible Operation: KINTEK manufactures tube furnaces for operating temperatures up to 2000°C (model specific). We offer vertical and horizontal tube models, bottom-loading vertical tubes, and combination units for maximum versatility.
- Customizable Options: Water-cooled end caps and gas mixing systems are available to tailor the furnace to specific experimental needs, reflecting KINTEK's commitment to providing customized solutions.
Advanced Safety Protections
- Kindle Tech tube furnace owns over-current protection and over-temperature alarming function; the furnace will turn off the power automatically once over-current is detected.
- The furnace has a built-in thermocouple detecting function; the furnace will stop heating and an alarm will be triggered if the thermocouple is broken or a failure is detected.
- The TF17 Pro (and similar advanced models) supports a power failure restarting function; the furnace will resume the heating program when power is restored after an outage.
Versatile Applications
The Tube Furnace With Alumina Tube is a versatile and essential tool in various high-temperature test and analysis scenarios across multiple industries. Its applications are particularly focused on environments requiring controlled heating zones and high-temperature resistance. Key application areas include:
- Material Science Research: Ideal for experiments involving the synthesis, processing, and characterization of new materials at high temperatures, including ceramics, composites, alloys, and refractory materials.
- Chemical Vapor Deposition (CVD) & Physical Vapor Deposition (PVD): Provides the controlled atmosphere and temperature necessary for thin film deposition processes.
- Sintering and Annealing: Used for densification of powders, stress relief, and microstructure modification of various materials.
- Coal Testing and Analysis: Employed for precise heating and analysis of coal samples to determine their properties (e.g., ash content, volatile matter) and suitability for various industrial uses.
- Metallurgical Powder Testing and Analysis: Essential for the heating and analysis of metallic powders, aiding in the development and quality control of metal alloys and composites.
- Chemical and Glass Industry Testing: Used in the heating and processing of glass and chemical samples for property analysis, crucial for developing new compositions and products.
- Pharmaceutical and Biotechnology Industries: Applicable for sterilization, purification, and processing of materials and equipment in controlled high-temperature environments.
Operating Principle
Tube furnaces utilize a heating element, such as a resistive heating coil (e.g., Cr2Al2Mo2 wire) or silicon carbide, to heat a process tube. This process tube, typically made of a high-purity ceramic material like alumina (Al2O3), is positioned within an insulated furnace chamber to minimize heat loss. The temperature inside the process tube is precisely regulated by a temperature controller (often PID-based), which monitors the tube's temperature via a thermocouple and adjusts the power supplied to the heating element accordingly. This controlled heating environment makes tube furnaces indispensable for a variety of applications, including heat treating, annealing, sintering, and material synthesis under controlled atmospheres or vacuum.
