Ultra -High Temperature Graphite Tube Furnace

This graphite tube furnace can be operated in either a horizontal and vertical position, and has a maximum operating temperatures to 3000°C. The tube diameter is 4″ and the available heated length is 8″ or 12″ long. This ultra high temperature furnace is a great tool for research and development.

A hollow tube is made from graphite, used for heating the sample (graphite tube furnace). The sample is located in the tube, and the furnace heats the tube to very high temperatures. In atomic absorption spectroscopy (AAS), for example, small quantities of sample are introduced into the tube and then specific heating is applied to vapourise the sample for analysis. They are also analytical and have a tube furnace that is used for sample heating.

This graphite tube furnace can be operated in either a horizontal and vertical position, and has a maximum operating temperatures to 3000°C.  The tube diameter is 4″ and the available heated length is 8″ or 12″ long. This ultra high temperature furnace is a great tool for research and development.

 

Switch seamlessly between vacuum (down to 10-2torr) and inert gas atmospheres (argon, nitrogen, helium) to protect sensitive materials, or utilize the optional muffle tube for oxidizing environments up to 1750°C.

 

The graphite tube furnace of features:

Ultra-high temperature performance: It can reach a temperature of up to 3000°C (5432°F), which can meet the needs of material research and industrial processing that have strict requirements for extreme high temperatures, and maintain stable thermal performance in high-temperature environments.

Excellent versatility: It supports both horizontal and vertical configurations, which can be flexibly adjusted according to the workflow; the heating length is available in 8 inches (203 mm) and 12 inches (300 mm), and the tube diameter is 4 inches (100 mm), which is suitable for both small-batch laboratory tests and large-scale industrial production. At the same time, it can seamlessly switch between vacuum (down to 10-2torr) and inert gas atmospheres (argon, nitrogen, helium) to protect sensitive materials, and can also be used in oxidizing environments through the optional muffle tube, with a maximum temperature of 1750°C.

Precise control capability: The temperature uniformity in the heating zone is within ±5°C, and the control accuracy reaches ±1°C, achieving precise temperature control with the help of advanced thermocouples and optical pyrometers. It supports programmed heating up to 30°C per minute, ensuring the repeatability of experimental or production results, and is suitable for various processes such as ceramic sintering, alloy annealing, and graphitization of carbon materials.

Durable and easy to maintain: It adopts an all-graphite hot zone and fiber insulation materials, which improves the efficiency and service life of the equipment; the quick-change furnace tube design reduces downtime for maintenance and improves work efficiency.

Enhanced safety guarantee: Equipped with a double-walled water-cooled chamber and an automatic air curtain door, it effectively prevents pollution and provides more reliable protection for operators.
