The Wincom Combustion Tube is a premium, high-temperature refractory chamber designed for elemental analysis, chemical vapor depositions, and gas-solid reactions inside horizontal tube furnaces. Forged from ultra-pure alumina ceramic or high-silica quartz, it acts as a reliable, vacuum-tight containment shield that withstands extreme thermal stress and high pressure gradients. This tube provides a completely inert, non-reactive environment, making it an indispensable tool for precise carbon and sulfur determination, sintering processes, and catalyst testing across research and industrial laboratories.

Technical Specifications

Key Features

• Superior Thermal Shock Resistance: Engineered with an exceptionally low thermal expansion coefficient, allowing the tube to maintain its structural integrity during rapid heating or cooling cycles without cracking.

• Ultra-High Gas-Tight Integrity: The high-density, non-porous material matrix prevents any atmospheric leakage, allowing technicians to run precise experiments under strict vacuum setups or inert gas purging (Argon/Nitrogen).

• Zero Elemental Background Bleeding: Built with high-purity raw minerals to guarantee that no trace carbons, sulfurs, or metallic contaminants gasify or bleed into the sample stream during high-temperature analysis.

• Straight and Uniform Geometry: Precision-molded with completely uniform wall thickness and excellent straightness parameters, ensuring balanced heat distribution and preventing localized thermal stress points.

• Heavy Chemical and Slag Defense: Highly resistant to acidic fumes, alkali vapors, and slag erosions, ensuring a long operational life even when continuously processing volatile metallurgical or chemical compounds.

Primary Applications

• Carbon and Sulfur Determination: Working as the main reaction chamber in automated elemental analyzers to combust samples of steel, iron, coal, and ore.

• Chemical Vapor Deposition (CVD): Serving as the high-purity process chamber for depositing thin films and synthesizing advanced nanomaterials or semiconductor substrates.

• Atmosphere Heat Treatments: Sintering, calcining, and annealing advanced ceramics, metallic powders, or catalysts under vacuum or controlled gas streams.

• Academic High-Heat Research: Providing a safe, closed thermal loop for university physics and chemistry students to study gas phase behaviors and high-temperature reactions.
