PYREX® 50 mm Hirsch Funnel with Coarse Porosity Fritted Disc – 36210-50C

The PYREX® 50 mm Hirsch Funnel with Coarse Porosity Fritted Disc (36210-50C) is a high-quality laboratory filtration funnel designed for efficient separation of solids from liquids, precipitate washing, and preparative laboratory procedures. Manufactured from durable PYREX® borosilicate glass, the funnel features an integrated 20 mm diameter coarse porosity fritted glass disc with a pore size range of 40–60 micrometres. This allows liquids to pass through while retaining appropriately sized solid particles, eliminating the need for conventional filter paper. Its Hirsch-type conical design facilitates convenient removal of collected precipitates, making it suitable for chemical laboratories, pharmaceutical research, educational institutions, industrial quality control laboratories, and general scientific applications. Key Features - 50 mm funnel diameter: Suitable for laboratory filtration and precipitate collection. - Coarse porosity fritted disc: Features a 40–60 µm pore size range for filtration of relatively large particles. - 20 mm integrated fritted disc: Provides a reusable glass filtration surface. - High-quality borosilicate glass: Offers chemical resistance and good thermal durability. - Hirsch-type conical design: Facilitates convenient removal and recovery of filtered precipitates. - Filter paper-free operation: Useful when solvents or reagents would damage ordinary filter paper. - Precision-controlled porosity: Manufactured with controlled pore classifications for consistent filtration. - Reusable and easy to maintain: Suitable for repeated laboratory applications with appropriate cleaning procedures. - Versatile applications: Ideal for chemical analysis, precipitate washing, crystallization work, and solid-liquid separation.
