Thermolyne F48020-DB Muffle Furnace, Single Setpoint, 5.8L, 240V

Thermolyne F48020-DB Benchtop Muffle Furnace, 5.8L, 240V

The Thermolyne Benchtop Muffle Furnace is an essential piece of laboratory equipment designed for high-temperature heating and analysis. It is ideal for a wide range of applications, including ashing, ignition tests, gravimetric analyses, and volatile matter determinations. For the construction and geotechnical sectors, this furnace is indispensable for testing materials such as soils, aggregates, and cement.

Constructed with rugged components and premium materials, this furnace is engineered for maximum durability and a long service life, ensuring reliable performance test after test.

Key Features and Controls

This model features a single set-point digital controller with a ramp function. This allows the furnace to heat directly to the desired temperature and dwell there for a specified period. The bright 0.3-inch (7.6mm) LED display clearly shows either the actual chamber temperature or the set-point, and can be switched between Celsius and Fahrenheit.

• Temperature Range: 100°C to 1200°C (212°F to 2192°F)
• Chamber Capacity: 5.8L (0.2ft³ or 350in³)
• Control: Single set-point controller with ramp-to-set-point functionality.

Advanced Safety and Performance

Operator safety and sample integrity are paramount. The furnace is equipped with several advanced features to ensure safe and efficient operation:

• Thermocouple Break Protection: Automatically cuts power to the heating elements if a thermocouple failure is detected, preventing overheating and potential damage.
• Door Safety Switch: An interlock system immediately cuts power to the heating elements when the furnace door is opened, protecting the operator from direct heat exposure.
• Over-temperature Protection: Guards against thermal runaway, preserving both the furnace and its contents.
• Efficient Heating and Insulation: Two open-coil heating elements on the chamber sides provide rapid and uniform heating. The entire chamber is encased in thermal-efficient ceramic insulation to maintain temperature stability and enhance energy efficiency.
• Venting System: A built-in vent port effectively removes moisture and contaminants during operation, which helps extend the life of the heating elements.
• Monitoring Port: A rear port allows for independent temperature monitoring with a separate measuring device, enabling precise calibration and verification.

Construction and Uniformity

This benchtop furnace is designed for optimal heating. Elements are located on the sides, top, and/or bottom. As the door and back are not heated, the central two-thirds of the chamber is considered the uniform temperature zone. It is important to select a chamber size that accommodates your samples within this uniform area.
