Filtering Funnels & Adapters
Filtering funnels, also named buncher funnels, are ideal for the filtration of solid particles from liquids or gases. The extractor system carries a cylinder separated from the funnel with a fritted glass disc. Ideal for vacuum-assisted filtering, these funnels are ideal for recrystallized compounds as they help remove moisture from the result.
Manufactured from high-quality materials, this ensures funnel durability and long-lasting performance. The user-friendly design ensures a controlled flow during filtration and removes any possibility of spillage to ensure safety and accuracy. Fritted glass disc options are immediately ready for use and save preparation time within the lab. The funnels are glazed from the outside and inside and available in various sizes to suit plenty of laboratory applications. Accessories available include filter paper and funnel adapters, ideal for detecting micro-organisms and ensuring accurate results.
Also available at Thomas Sci – flasks, funnels, and other glassware.
