Filter funnel with glass disc

Filter Funnel with Glass Disc - Laboratory Filtration Equipment

Our premium filter funnels with glass disc are essential laboratory glassware designed for efficient filtration processes in analytical chemistry, research, and quality control applications. These precision-engineered funnels feature integrated glass discs that provide superior filtration performance while maintaining chemical resistance and durability for demanding laboratory environments.

Key Features

• Integrated glass disc with precise porosity for optimal filtration efficiency
• Borosilicate glass construction ensuring excellent chemical resistance
• Standard ground glass joints for secure connections to vacuum systems
• Smooth interior surfaces preventing sample retention and contamination
• Heat-resistant design suitable for high-temperature applications
• Multiple porosity grades available to meet specific filtration requirements

Applications

These laboratory filter funnels are ideal for gravimetric analysis, sample preparation, crystallization processes, and separation of precipitates. They excel in pharmaceutical testing, environmental analysis, food quality control, and academic research where precise filtration is critical for accurate results.

Technical Specifications

Available in various sizes from 25mm to 90mm diameter, our glass disc filter funnels feature porosity ratings from coarse to extra fine (P1 to P5). The borosilicate glass construction ensures compatibility with most solvents and reagents, while standard taper joints provide leak-proof connections to filtration apparatus and vacuum systems.
