PYREX® 50 mm Hirsch Funnel with Fine Porosity Fritted Disc – 36210-50F

The PYREX® 50 mm Hirsch Funnel with Fine Porosity Fritted Disc (36210-50F) is a precision laboratory filtration funnel designed for efficient separation of fine solid particles from liquids, precipitate recovery, and chemical preparation procedures. Manufactured from high-quality PYREX® borosilicate glass, this Hirsch-type funnel features an integrated 20 mm diameter fine porosity fritted glass disc with a pore size range of 4–5.5 micrometres. Its fine filtration capability makes it particularly suitable for collecting small precipitates and performing filtration procedures requiring effective particle retention. The specially designed angled funnel body facilitates convenient removal of filtered precipitates, while the fritted glass disc eliminates the need for conventional filter paper. It is especially useful when washing or redissolving precipitates with chemicals that could damage traditional paper filtration media. Suitable for chemical laboratories, pharmaceutical research facilities, educational institutions, industrial quality control laboratories, and scientific research centres.
