Description
Büchner funnel Ø 45 mm is a glazed porcelain laboratory funnel for vacuum filtration, designed for filter paper of 45 mm diameter and manufactured in accordance with DIN 12905. The porcelain construction with glazed surface provides a durable vessel for solid-liquid separations in analytical and preparative workflows. Offered as one piece, this mid-size Büchner funnel from manufacturer Witeg fits routine chemistry, pharmaceutical and teaching laboratory applications. During filtration the perforated plate supports the filter medium while filtrate is drawn into a receiving flask under reduced pressure. Net weight is 0,074 kg, giving a stable yet manageable component for bench-top filtration assemblies. Common uses include recovery of precipitates, isolation of crystalline products after recrystallisation, and clarification of suspensions at moderate sample volumes. Compliance with DIN 12905 helps ensure reliable seating of 45 mm filter paper discs. The glazed finish simplifies cleaning between runs and suits everyday laboratory solvents when handled under normal conditions. This Ø 45 mm porcelain Büchner funnel serves as a practical nutsche-style tool for consistent vacuum filtration tasks.
