AONES’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.
