PYREX® 50 mm Hirsch Funnel with Medium Porosity Fritted Disc – 36210-50M

The PYREX® 50 mm Hirsch Funnel with Medium Porosity Fritted Disc (36210-50M) is a high-quality laboratory filtration funnel designed for efficient separation of solid particles from liquids, precipitate recovery, and preparative chemical procedures. Manufactured from durable PYREX® borosilicate glass, this Hirsch-type funnel features an integrated 20 mm diameter medium porosity fritted glass disc with a pore size range of 10–15 micrometres. The medium porosity filtration surface provides effective particle retention while allowing suitable liquid flow during filtration procedures. The funnel's angled body facilitates convenient removal of collected precipitates, making it particularly useful for applications involving washing, filtration, and redissolving solids using chemicals that may damage conventional filter paper. Designed for repeated laboratory use, this funnel is suitable for analytical chemistry laboratories, pharmaceutical research, educational institutions, chemical processing facilities, industrial quality control laboratories, and scientific research centres. Key Features - 50 mm funnel diameter: Provides a convenient opening for laboratory filtration procedures. - Medium porosity fritted disc: Features a 10–15 µm pore size range for effective solid-liquid separation. - 20 mm integrated fritted glass disc: Offers a reusable filtration surface without requiring conventional filter paper. - Premium borosilicate glass: Provides excellent chemical resistance and good thermal durability. - Hirsch-type angled design: Facilitates convenient removal and recovery of collected precipitates. - Efficient filtration: Provides a balance between filtration flow rate and particle retention. - Chemical-resistant construction: Suitable for procedures involving chemicals that may attack ordinary filter paper. - Controlled porosity: Fritted discs are individually tested and graded for consistent filtration performance. - Reusable and easy to maintain: Suitable for repeated laboratory applications with appropriate cleaning and handling. - Versatile laboratory applications: Ideal for analytical chemistry, precipitate washing, crystallization, sample preparation, and pharmaceutical research.
