Tube Furnace

A tube furnace is an essential piece of equipment in the fields of material science, chemistry, and engineering, serving a pivotal role in controlled, high-temperature processing. Characterized by their cylindrical heating chambers, tube furnaces are designed to uniformly heat materials placed within them. The inception of these furnaces traces back to the early 20th century, driven by the demand for precise temperature control in a variety of industrial and scientific research applications.

Vacuum Tube Furnace

Vacuum Tube Furnace

Crucial for conducting materials research in reduced atmospheres or specific gas environments.

High Vacuum Tube Furnace

The high vacuum tube furnace can maintain pressures below 10^-7 torr, essential for minimizing oxidation and other gas-related reactions to prevent contamination. This capability is crucial in fields like materials science and nanotechnology, where precise atmospheric control is necessary for accurate material studies and synthesis.

High Temperature Tube Furnace

High Temperature Vacuum Tube Furnace

High temperature tube furnaces are specifically designed to achieve extremely high temperatures, often up to 1800°C or more. This capability allows processing materials that require very high heat, such as advanced ceramics and material synthesis.

Laboratory-scale Rotary Kiln

Rotary Kiln for Labs

Laboratory rotary kilns are often used for pilot-scale studies or small production runs in research and development labs in industries. It typically operate under ambient atmospheric conditions or sometimes under a controlled but not completely vacuumed environment.

Vacuum Rotary Tube Furnace

Similar in basic design to rotary kilns, these furnaces have additional features to maintain a vacuum and control the atmosphere inside. Vacuum rotary furnaces provide superior temperature and environmental control, which is crucial for processing materials that are highly reactive or require high purity.
