Buchner Funnel

The Buchner Funnel with a Fritted Disc represents the pinnacle of precision glassware for high-performance vacuum filtration. Unlike traditional Buchner funnels that require filter paper, this advanced apparatus integrates a permanent, fusedglass disc (frit) directly into the glass body above the stem.

This crucial feature eliminates the hassle, cost, and risk of contamination associated with filter paper. The fritted disc provides an extremely robust and chemically inert support structure for your filter cake. Manufactured from premium Borosilicate 3.3 Glass, this funnel offers superior resistance to nearly all corrosive chemicals, heat, and thermal shock.

The key to its versatility is the specified porosity of the disc (e.g., Coarse, Medium, Fine, or Ultra-Fine). By choosing the correct porosity grade, you can precisely control the retention of particles without the need for additional media, ensuring faster flow rates and superior solid-liquid separation.

Sizes other than those listed are available, please call for pricing.
