Cytiva, 4019, Fritted glass support base/No. 8 silicone stopper (1/Pk)

Made of 100% borosilicate glass, assures resistance to even the most aggressive solvents. One-liter 47 mm glass funnel/support assembly permits filtration of an entire liter at once. Support assembly's unique base design with integral vacuum connection prevents contamination of the vacuum line with filtrate. One-liter glass funnel is graduated from 300 to 1,000 mL in 50 mL increments. 300 mL glass funnel is graduated from 100 to 250 mL in 25 mL increments. Stepped stem fits into standard one-hole stoppers (9 mm). 47 mm Glass Filter Funnel with Stopper Support Assembly Materials of Construction All parts are borosilicate glass except: Stopper: Silicone No. 8 Clamp: Aluminum Effective Filtration Area 9.6 cm ^2 Dimensions Overall Height: (Base: 11.7 cm (4.6 in) Funnel: 11.1 cm (4.4 in) Diameter: Base: 5.8 cm (2.3 in.)
