UNIVERSAL TUBE FURNACES – FAQ
WHAT IS THE MAXIMUM TEMPERATURE IN A TUBE FURNACE?
Quartz tube furnaces can operate at maximum temperatures ranging from 1200°C to 1700°C. The specific temperature depends on the product range and type of heating elements used in the furnace’s construction.
HOW DOES A TUBE FURNACE WORK?
A tube furnace heats samples inside a work tube. After installing the work tube and loading the samples, you input a setpoint into the furnace controller, and the temperature increases accordingly. The heat applied around the work tube gradually warms the samples inside.
WHAT DIAMETERS AND LENGTHS ARE AVAILABLE FOR A QUARTZ TUBE FURNACE?
Standard tubular furnaces come in a variety of lengths and diameters. They range from the smallest, with a 200mm heated length and 25mm outer diameter, to the largest, with a 1200mm heated length and 200mm outer diameter. Custom lengths and diameters are also available upon request.
DO I NEED A WORK TUBE TO OPERATE MY TUBE FURNACE?
You should always operate a tube furnace with a work tube to contain samples and protect the heating elements. Different shaped vessels can contain samples, as long as they are well-supported and do not contact the heating elements.
WHAT TYPES OF WORK TUBES ARE SUITABLE FOR A TUBULAR FURNACE?
Tubular furnaces typically operate with work tubes made of ceramic materials (like mullite or recrystallized alumina), quartz glass, or metals (such as stainless steel or Inconel). The work tube material should be suitable for your application. It must withstand the maximum operating temperature and resist chemical reactions with the sample materials.
