Advantec's Polysulfone 47mm Filter Holders are an economical alternative to glass vacuum holders. The durable polysulfone plastic construction is chemically resistant and can withstand mishandling. The recessed polypropylene filter support provides sufficient clearance so the membrane will not tear when the funnel is secured to the base. Funnel and base connect with a simple twist of a hand. Graduated funnels available in 300 mL, 500 mL wide mouth, and 800 mL capacities. All models are supplied with silicone rubber O-rings and No.8B silicone stopper. The No.8B stopper mounts in a standard 1 L side-arm flask or standard cup manifold. Funnels with covers can be vented aseptically using a hydrophobic syringe filter(13JP050AN). Units with covers are supplied with gum rubber caps. FPM O-rings are available. Aseptic System with Receiver also includes a receiver cover and the 11mm OD hose adaptor accepts 3/8" tubing.
