Description
Büchner funnel Ø 320 mm is a large glazed porcelain funnel for vacuum filtration using filter paper of 320 mm diameter. Manufactured according to DIN 12905, the Büchner geometry provides a perforated support plate that holds the filter medium securely under suction when separating solids from liquids. The glazed porcelain construction delivers chemical durability and thermal stability for demanding preparative and analytical filtration tasks. With a 320 mm working diameter, the funnel is suited to higher sample loads and bulk recovery of precipitates or crystalline products. Offered as a single unit with a net weight of 9 kg, this funnel from manufacturer Witeg integrates into conventional vacuum filtration setups with appropriate adapters and receiving flasks. Applications span process-scale laboratory filtration, sample work-up and solid isolation after synthesis or crystallisation. The robust porcelain body supports repeated use and thorough cleaning, making it a dependable component for research, production-support and teaching laboratories that need a large-format Büchner funnel built to recognised dimensional standards.
