Filter funnels

Filter Funnels - Laboratory Glassware

Filter funnels are essential laboratory glassware designed for efficient solid-liquid separation and filtration processes. These precision-engineered funnels feature integrated filter plates or perforated bottoms that enable effective filtration while maintaining chemical resistance and durability in demanding laboratory environments.

Key Features

• High-quality borosilicate glass construction for superior chemical resistance
• Precision-manufactured filter plates with uniform pore distribution
• Various pore sizes available for different filtration requirements
• Heat-resistant design suitable for hot filtration applications
• Smooth interior surfaces minimize particle retention
• Compatible with standard laboratory filter papers
• Available in multiple sizes from 25mm to 150mm diameter

Applications

Filter funnels are widely used in analytical chemistry, quality control laboratories, and research facilities for gravimetric analysis, sample preparation, and purification processes. They excel in crystallization procedures, precipitate collection, and routine filtration tasks in pharmaceutical, chemical, and academic laboratories.

Technical Specifications

Our filter funnels comply with international laboratory standards and feature precise pore sizes ranging from coarse (40-100 μm) to extra fine (4-10 μm). The borosilicate glass construction ensures thermal shock resistance up to 500°C and excellent chemical compatibility with acids, bases, and organic solvents.
