Abstract
A device is disclosed for holding a membrane filter with use of a porous metal disk support for a membrane. In the method of assembly the metal disk and membrane are sealed to a fusible enclosure by heat formed in the metal disk by induction heating. Such heat seals the metal disk and also seals the surface of the membrane to the fusible surrounding enclosure. The device is particularly useful in filtering particulate matter from intravenous solutions administered into the circulatory system of a human.
