Funnel Stands

The standout innovation of these filtration racks lies in their screwless magnetic height adjustment system. Unlike traditional metal support stands that rely on tedious thumb screws or mechanical clamps that corrode and slip, Burkle's funnel holders utilize internal high-strength magnets. Technicians can smoothly reposition holders along the chrome-plated steel rod using just one hand, securing the ring instantly at any height up to 450 mm. Each positioner accepts funnels ranging from 40 mm to 180 mm in outer diameter when utilizing the included adapter rings.

Key Functional Benefits:

• Screwless Magnetic Height Adjustment: High-strength internal magnetic core enables stepless, one-handed vertical positioning up to 450 mm, eliminating slipping thumb screws and thumb wear.
• Broad Funnel Compatibility: Accommodates large analytical and powder funnels up to 180 mm in diameter, while included reducing inserts allow secure seating for micro-funnels down to 40 mm.
• Chemical-Resistant & Shatterproof Construction: Molded polypropylene (PP) base plate and holders resist aggressive acids, alkalis, and organic solvent spills while maintaining exceptional impact strength.
• Integrated Drip/Storage Channels: The heavy base plate features molded storage depressions to catch minor drips and hold auxiliary laboratory supplies or receiver vessels.
• Versatile Multi-Position Formats: Available in space-saving 2-funnel double inline and 4-funnel quad square configurations to optimize benchtop space.

Chemical Resistance: The polypropylene base, PVC accents, and chrome-plated steel rod resist brief exposure to common acids and bases. Promptly wipe away highly concentrated, hot oxidizing acids to preserve surface finish.
