The Wincom Evaporating Dish is a professional-grade laboratory vessel designed to evaporate excess solvents—mainly water—to produce a concentrated solution or a solid precipitate of the dissolved substance. Crafted from premium high-purity porcelain, this dish features a shallow, wide-mouthed configuration that maximizes the surface area of the liquid, significantly accelerating the rate of evaporation. Outfitted with a non-drip pouring spout, it is a crucial tool for chemical processing, sample concentration, quantitative analysis, and general laboratory heating workflows.

Technical Specifications

• Equipment Type: Round-Bottom Evaporating Dish with Spout

• Material Composition: High-grade, thermal-shock resistant laboratory porcelain (Alumina-Silicate ceramic)

• Surface Treatment: Highly polished internal glaze; exterior glazed up to the flat or round base line

• Thermal Performance: Safely handles direct heat up to 1050°C without cracking or structural deformation

• Available Volumetric Capacities: Diverse size range (e.g., 35ml, 50ml, 75ml, 100ml, 150ml, up to 250ml or larger)

• Pouring Interface: Integrated, precision-molded pouring lip for clean, drop-free liquid transfers

• Chemical Stability: High resistance to acids, alkalis, and aggressive organic solvents at boiling points

Key Features

• Optimized Wide-Surface Geometry: The shallow, open-bowl design ensures the maximum possible liquid-to-air surface interface, promoting fast and efficient evaporation over wire gauzes, hotplates, or water baths.

• Thermal Shock Endurance: Engineered with a low coefficient of thermal expansion, allowing the dish to endure high-temperature stress from open flames, Bunsen burners, and sudden temperature variations.

• Ultra-Smooth Glazed Interior: The glass-like, non-porous internal glaze prevents residual solids and crystals from embedding into the walls, ensuring easy cleaning and maximum sample yield recovery.

• Precision Non-Drip Pouring Spout: Built with a distinctive sharp pouring lip that guides hot liquids or dense concentrates smoothly into collecting flasks without messy running down the sides.

• Inert Chemical Defense: Resistant to almost all standard laboratory reagents and acids, preventing cross-contamination and maintaining the high-purity requirements of analytical chemistry protocols.

Primary Applications

• Solvent Evaporation and Concentration: Boiling away water or organic solvents from a solution to leave behind dry, crystallized chemical salts or solid materials.

• Quantitative Gravimetric Analysis: Heating or incinerating samples to determine total dissolved solids (TDS) or dry mass content in environmental and industrial laboratories.

• Recrystallization Processes: Concentrating hot solutions down to the saturation point before cooling to grow pure chemical crystals.

• Educational Chemistry Labs: Providing a rugged, heat-safe container for school and college students to observe fundamental physical changes, separation techniques, and chemical reactions.
