- Description
Description
Buchner Funnel Porcelain is designed for efficient vacuum filtration where fast liquid removal, reliable solid retention, and durable bench performance are essential. Used with filter paper and a compatible vacuum filtration flask, a porcelain Büchner funnel supports rapid separation of precipitates, crystals, and suspended solids from liquids, making it ideal for teaching laboratories, research workflows, and routine quality control sample preparation. The straight sided cup design helps hold the filter cake securely during washing and recovery steps, improving filtration efficiency and handling.
Manufactured from high quality laboratory porcelain, the funnel offers strong mechanical durability and good resistance to many common laboratory reagents under routine filtration conditions. The glazed surface supports easier cleaning and helps reduce residue build-up between runs, while the perforated plate provides stable support for filter paper and promotes even vacuum distribution across the filtration area. This helps maintain consistent flow and reduces the risk of filter paper collapse during suction.
For best performance, match the funnel diameter to the correct filter paper size, use a suitable rubber cone adapter for a secure seal on the filtration flask, and inspect the funnel for chips or cracks before use. Avoid sudden temperature changes to reduce thermal shock risk and extend service life in daily laboratory use.
Quality standards reference: manufactured under ISO 9001 quality management systems where applicable, with ceramic whiteware quality verification commonly referenced to ASTM C373 for water absorption, bulk density, apparent porosity, and apparent specific gravity testing of fired whiteware products.
