Abstract

A filter funnel incorporates a conical base, a filter element, a flexible joint and a cylindrical upper vessel, which are separable. The base has a shoulder and is widened and flat at the edge so as to receive the filter element and the joint. The vessel has a flat part at one end which holds the filter element and the joint in the shoulder. The base and the vessel are held together by simple clips. The other end of the base is joined to a tube with a bevelled or a ground joint. The flexible joint may be in PTFE, PVC or other material. The filter element is a porous plate which may have any suitable porosity. The whole of the filtered product is recoverable by lifting out the plate after removing the upper vessel. The funnel may be of different materials, e.g. glass, steel, stainless steel, plastic, ceramic. In research, synthesis or control laboratories, chemical factories, pharmaceutics, electronics etc. Recovery of solids, and cleaning of the appts. are much simpler than in existing appts. in which the filter plate is solid with the rest of the appts.
