Table-top Buchner funnels with coarse porosity (90-130 microns) with a removable punctured filter plate. The high density polyethylene rigid plate is 4.8mm (3/16") thick. Holes are 4.8mm (3/16") diameter on 11mm (7/16") centers. A removable filter plate allows easier cleaning and…

Glassware system for vacuum filtration using 47mm membranes. This assembly uses a standard taper 40/35 joint to connect the support base to the filtering flask, eliminating the possiblility of phthalate contamination from rubber stoppers. Recommended for filtering corrosive solutions, particulate…

Clear polysulfone funnel with imprinted graduations. Magnetic coupling of funnel to stem for fast filter changes. Used with 47 mm membrane filters for coliform testing and prefiltration of many fluids. Fits standard manifold systems with #8 rubber stopper connections. Capacity 300 mL (10 oz).…

Glass Long Stem Funnels, 60 degree angle, Stem length is 150mm.

Set of seven neoprene adapter cones designed to fit Buchnew and fritter glass funnels, porcelain filters without headpieces, and for reverse flow cleaning for filter crucibles. Adapters can be used to support funnels, Gooch crucibles, filter tubes and other apparatus in filtration…

Economical, disposable and sterile Features a graduated, “peel-away” upper, which easily separates from the collar to allow quick retrieval of the cellulose nitrate membrane for microbiological analysis 250 mL, polypropylene upper with 47 mm, 0.2 or 0.45 µm membrane The 0.45 µm…

Useful for direct filtration applications of small volumes under vacuum. Complete apparatus consists of a Buchner funnel with 14/20 top outer and lower inner joints, and a 50mL Erlenmeyer flask having a 14/20 outer joint.

Unique gravity-sealing design Two-piece construction One-handed operation Large membrane access points for forceps Available in polysulfone or polypropylene No clamps or locking devices to manipulate. Less expensive than stainless steel, glass or magnetic funnels, yet compare favorably with…

With fixed perforated plate Glazed except for rim

Table-top Buchner funnels with medium porosity (45-90 microns) fixed filter plates are 6.4mm (1/4") thick high density polyethylene with a non-porous circumference to better fasten filter paper to the plate. The high density polyethylene rigid plate is 4.8mm (3/16") thick. Holes are 4.8mm…
