The Wincom Combustion Boat is a highly specialized, ultra-high-temperature refractory vessel designed for elemental analysis, organic compound incinerations, and metallurgical testing inside tube furnaces. Forged from high-purity porcelain or unglazed alumina ceramic, its narrow, elongated design allows it to slide effortlessly into standard quartz or ceramic combustion tubes. Engineered to withstand intense thermal shocks and extreme heat spikes without structural failure, this vessel provides a non-reactive base that ensures precise, contamination-free testing for carbon, sulfur, and alloy verification assays.

Technical Specifications

• Equipment Type: High-Temperature Laboratory Combustion Boat / Sample Tray

• Material Composition: Ultra-pure unglazed Alumina ($Al_2O_3$) ceramic or high-grade thermal porcelain

• Geometric Structure: Narrow, low-profile elongated rectangular trough with open or eyelet handles

• Thermal Endurance Range: Safe for continuous operations up to 1050°C to 1200°C (Alumina variants stable up to 1600°C)

• Available Dimensional Profiles: Multiple lengths and widths tailored to fit standard tube furnace inner diameters (e.g., 77mm, 88mm, 97mm, or 100mm lengths)

• Handling Features: Integrated small outer loop/eyelet at one end for seamless insertion and extraction via boat-pulling hooks

• Chemical Resistance: Exceptional resistance to aggressive alkaline fluxes, volatile chemical vapors, and slag erosions

Key Features

• Exceptional High-Heat Deflection: Engineered with a near-zero coefficient of thermal expansion, preventing cracking, breaking, or bending when introduced directly into hot, pre-heated tube furnace chambers.

• Zero Elemental Contamination: The ultra-pure ceramic matrix contains negligible trace minerals, ensuring that zero foreign carbon, sulfur, or metal elements bleed into the target sample during processing.

• Slag and Erosion Resistant Build: Features high-density, non-porous sidewalls that resist chemical erosion from melted metals, hot chemical fluxes, and corrosive gas streams.

• Dedicated Eyelet Pull Interface: Designed with a built-in eyelet or specialized ridge on the leading edge, allowing technicians to pull hot boats out safely with a steel hook without risking hand burns or dropping samples.

• Flat Non-Slip Base Contact: Outfitted with a precision-ground, unglazed flat bottom that ensures stable seating on furnace tubes, avoiding accidental tilting or chemical spilling during heating loops.

Primary Applications

• Carbon and Sulfur Analysis: Serving as the sample vehicle inside automated elemental analyzers to measure carbon and sulfur volumes in steel, coal, and soil.

• High-Temperature Tube Melting: Holding small alloy samples or specialized chemical powders inside horizontal tube furnaces under vacuum or inert gas conditions.

• Ashing and Ignition Assays: Vaporizing volatile elements from complex mineral compounds to evaluate total ash weights and raw dry masses.

• Catalyst and Semiconductor Treatment: Sintering, firing, or baking delicate industrial crystal substrates and catalysts away from open atmospheric contamination.
