PYREX® 350 mL Buchner Funnel with Fine Fritted Disc – 36060-350F

The PYREX® 350 mL Buchner Funnel with Fine Fritted Disc (36060-350F) is a high-quality laboratory filtration apparatus designed for efficient solid-liquid separation, fine particle filtration, vacuum filtration, and chemical sample preparation. Manufactured by Corning from durable PYREX® borosilicate glass, this funnel features an integrated 80 mm diameter fine-porosity fritted glass disc with a pore size range of 4–5.5 micrometres. The built-in porous glass disc enables filtration without conventional filter paper in suitable applications, particularly when handling chemical substances that may attack or damage ordinary filter paper. Its 350 mL capacity, chemically resistant construction, reinforced beaded rim, and reusable filtration surface make it suitable for pharmaceutical laboratories, analytical chemistry, universities, industrial quality control laboratories, chemical processing facilities, and scientific research institutions. Key Features - 350 mL capacity: Suitable for medium-volume laboratory filtration and sample preparation. - Fine porosity filtration: 4–5.5 µm pore size for retaining fine particles. - 80 mm fritted glass disc: Provides a wide, integrated filtration surface. - PYREX® borosilicate glass: Offers excellent chemical resistance and thermal durability. - Filter paper-free filtration: Eliminates the need for separate filter paper in suitable applications. - Vacuum filtration compatibility: Suitable for compatible laboratory vacuum filtration systems. - Beaded upper rim: Provides a smooth, reinforced funnel opening. - Reusable construction: Can be cleaned and reused following appropriate laboratory procedures. - Chemical resistance: Suitable for many laboratory reagents that may damage conventional filter paper. - Laboratory-grade design: Supports analytical testing, chemical processing, and research applications.
