High Temperature Hybrid Muffle and Tube Furnace 1700C Programmable PID Controlled Box System with Vacuum Flange and Alumina Processing Tube

Product Overview

This high-temperature hybrid furnace represents a sophisticated advancement in laboratory thermal processing, ingeniously combining the capabilities of a 1.7-liter muffle furnace with a 1-inch internal diameter tube furnace. Engineered for material science researchers and industrial R&D departments, this equipment serves as a space-saving, dual-mode solution for high-precision heat treatments. The primary value proposition lies in its versatility: it functions as a compact box furnace for bulk sample processing while seamlessly transitioning into a vacuum-sealed tube furnace for controlled atmosphere experiments. By integrating these two essential laboratory tools into a single, compact footprint, the system reduces capital expenditure and optimizes laboratory real estate without compromising on high-temperature performance or accuracy.

Designed for rigorous academic and industrial applications, the unit is frequently utilized in chemical vapor deposition (CVD), sintering of advanced ceramics, and the annealing of specialized metallic alloys. The robust construction allows it to thrive in environments requiring consistent high-temperature cycles up to 1700ºC. Target industries include semiconductor manufacturing, aerospace material testing, and battery research, where the ability to switch between atmospheric box processing and vacuum-sealed tube processing is critical for iterative prototyping. This dual-purpose architecture ensures that researchers can move from sintering bulk powder samples to performing specialized thin-film growth or atmosphere-controlled reduction without switching equipment.

Operational reliability is the cornerstone of this system's design. Utilizing 1800ºC grade Molybdenum Disilicide (MoSi2) heating elements and high-purity alumina fiber insulation, the equipment is built to withstand demanding thermal profiles. The integration of advanced PID control logic ensures that the thermal environment remains stable and repeatable, minimizing batch-to-batch variation. Every component, from the heavy-duty vacuum flanges to the precision-machined alumina tube, is selected to ensure performance longevity and structural integrity under high-vacuum and high-temperature conditions. Users can operate with confidence, knowing the system provides the thermal consistency required for high-stakes research and industrial-grade quality control.

Key Features

• Dual-Mode Hybrid Architecture: This system provides the unique capability to function as both a 1.7L muffle furnace and a high-performance tube furnace. A precision-machined 40mm access port in the front door allows for the insertion of a high-purity alumina tube, enabling users to switch between bulk sample heating in the chamber and controlled atmosphere processing within the tube in minutes.

• High-Temperature MoSi2 Heating Elements: Equipped with four U-shaped 1800ºC grade Molybdenum Disilicide heating elements, the furnace achieves a maximum working temperature of 1700ºC. These elements are specifically chosen for their exceptional oxidation resistance and ability to maintain structural integrity during rapid thermal cycling, ensuring a long service life in industrial environments.

• Advanced 30-Segment PID Controller: The unit features a high-precision digital temperature controller with Proportional-Integral-Derivative (PID) logic. It allows for the programming of up to 30 segments, including specific ramping rates, dwelling times, and cooling steps, providing total control over the thermal profile with an accuracy of ±1ºC.

• Integrated Vacuum and Atmosphere Control: When configured in tube mode, the system includes a complete vacuum flange kit with high-quality valves, a mechanical vacuum gauge, and a KF25 port. This setup facilitates high-vacuum operations reaching 10-2 torr with mechanical pumps or 10-5 torr with turbo-pumps, as well as the introduction of inert or reactive gases for specialized material synthesis.

• High-Efficiency Fibrous Alumina Insulation: The heating chamber is lined with premium-grade alumina fiber insulation, which offers superior thermal reflectance and low heat storage. This engineering choice results in faster heating rates (up to 20°C/min), improved energy efficiency, and a cooler outer shell temperature during operation.

• Safety and Monitoring Systems: Safety is prioritized with built-in over-temperature and thermocouple failure alarms. The system utilizes an S-type thermocouple for reliable high-temperature measurement and includes an integrated air breaker to protect the electrical circuitry from surges or malfunctions.

• Precision Loading Interface: The ergonomic drop-down door design serves a dual purpose: it provides a stable platform for easy sample loading when used as a box furnace and acts as a secure support structure when the alumina tube is installed, preventing mechanical stress on the ceramic components.

• Data Connectivity and Software Support: A default DB9 PC communication port is integrated, allowing for remote monitoring and data logging. Optional Labview-based software enables researchers to edit temperature profiles, manage complex heat-treatment recipes, and record real-time data for audit trails and publication-quality reporting.
