1400℃ Laboratory High Temperature Tube Furnace with Alumina Tube

Introduction

The tube furnace with alumina tube is a piece of laboratory equipment designed for high-temperature applications up to 1400°C. It is commonly used in a variety of processes in research and industrial settings, such as material synthesis, chemical vapor deposition, vacuum sintering and heat treatment. The heating elements, typically made of silicon carbide (SiC), are arranged in the furnace insulation layer outside the alumina tube. The high-purity alumina ceramic tube serves as the central reaction chamber, holding samples and experimental atmospheres while providing excellent thermal stability, high temperature resistance, and resistance to acids and alkalis.

Features

Tube furnaces with alumina tubes are ideal for applications requiring relatively small workspaces and features such as multiple zones, independently controlled. Alumina tubes are required for high-temperature operation, but they are subject to thermal shock. The smaller the diameter of the process tube, the better. KINTEK manufactures tube furnaces for operating temperatures up to 2000 degrees centigrade. In addition to vertical and horizontal tube models, we offer a bottom-loading vertical tube and combination units that allow the tube to be placed either vertically or horizontally. Water-cooled end caps and gas mixing systems are optional.

Warnings

Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
