What is a Laboratory Electric Furnace?

A laboratory electric furnace is one of the essential pieces of equipment used in laboratories for applying high temperatures to samples. These furnaces utilize heating elements to warm the internal chamber and achieve temperatures far above ambient conditions. Depending on the type and application, electric furnaces can be adjusted across a wide range of temperatures.

The furnace features a fully insulated chamber made of refractory bricks. It can generate temperatures as high as 1200°C, making it suitable for melting certain materials or determining ash content.

In some cases, this device is referred to as a furnace, electric furnace, laboratory furnace, or oven. It is commonly employed in laboratories and research centers for thermal experiments and processes that require extremely high temperatures.

Laboratory furnaces are one of the most widely used yet highly wear-prone devices. Operating at high-temperature ranges for extended periods makes them one of the most sensitive laboratory devices, increasing the design and manufacturing complexity of these units.

Types of Laboratory Electric Furnaces

Laboratory furnaces are typically classified into Muffle Furnaces, Tube Furnaces, and Microwave Furnaces, available in various sizes to meet different needs. Temperature ranges vary from 1100°C to 3000°C. Naturally, as the temperature range increases, the type of insulation and the heating element materials become more critical. Furnaces can also be categorized based on body material, type of controller, and temperature range.

Here are some common types of laboratory furnaces:

1. Tube Furnace: Composed of ceramic or metal tubes surrounded by heating elements, suitable for experiments requiring controlled gas flow or specific atmospheric conditions.
2. Muffle Furnace: Features a fully enclosed, insulated chamber to prevent direct contact between samples and combustion gases or flames.
3. High-Temperature Research Furnace: Designed for experiments that require extremely high temperatures.
4. Vacuum Furnace: Operates in a vacuum environment, ideal for processes such as degassing samples.
5. Atmosphere-Controlled Furnace: Precisely regulates the flow and composition of gases within the chamber.
6. Arc Furnace: Utilized for melting metals and other materials under extremely high temperatures.
7. Ashing Furnace: Specifically for burning organic samples to determine the amount of residual mineral content.

Each type has unique features and configurations that make them suitable for specific tests and industrial processes.

Key Features of Advanced Furnaces

Electric furnaces usually come with temperature controllers, air exhaust vents (to remove vapors and gases), and timers. Advanced models, such as the FG furnaces, include features like:

• Programmable settings
• Thermal ramp control
• Delayed start timers

FG furnaces are designed with international standards to cater to a wide range of user needs. Notable features include advanced microcontrollers, programmability, and thermal ramp control. FG designers guarantee that these models are competitive with European brands, ensuring user satisfaction upon evaluation.

Important Considerations When Purchasing a Laboratory Furnace

High chamber temperatures can produce vapors and gases, leading to corrosion and damage to heating elements. In muffle furnaces, embedding the heating element inside refractory materials protects it from the effects of emitted gases, thereby extending its lifespan. The presence of an air exhaust vent also enhances the longevity of heating elements by effectively removing vapors and gases.

FG furnaces are currently available in volumes of 2, 4, 6, and 8 liters, with models including FM2P, FM4P, FM6P, and FM8P. Custom designs are also available upon request.

1200°C Furnace

The outer body of this device is made from electrostatic powder-coated iron sheets, while the internal chamber of FG furnaces is constructed from refractory bricks and castable refractory material. The heating elements are independently positioned along the sidewalls using the CHP method, making replacement easy. The air exhaust vent, conveniently located, allows users to expel vapors and gases from the chamber, preventing element corrosion.

The 1200°C FG furnace features a state-of-the-art controller with advanced microprocessors. These intelligent controllers contribute significantly to precise temperature control and thermal stability. Additionally, the unique air exhaust mechanism enhances usability and has been widely praised by users in this field.

Models include FM2P, FM4P, FM6P, and FM8P, which can be customized based on specific customer needs.
