Abstract: The present invention relates to an improvement to the treatment of needles for safe disposal. The device comprises a support member having at least one recess. Each said at least one recess is configured to receive a needle contained in a corresponding plastic needle cap. The device further comprises a heating element configured to heat the support member, such that the plastic material of the needle cap softens and flows to encapsulate the corresponding needle. Each said at least one recess has dimensions such that, after heating, the needle is fully encapsulated by the plastic material of the corresponding needle cap. A corresponding method is disclosed.

Abstract: A filter element is assembled by first fixturing the parts together so that the assembly may be manipulated by automated assembly equipment before the end cap sealant is fully cured in an oven which is off-line from the automated assembly equipment. In one embodiment, a plastisol sealant is used, which is "kiss-gelled" by rapidly increasing the temperature of the sealant for a few seconds to cure the sealant sufficiently to permit the assembly to be handled but without fully curing the sealant. The end cap on the other end of the assembly is then installed and kiss-gelled before the completed (but uncured) assembly is transferred to a curing oven where the plastisol at both ends of the assembly is fully cured at the same time.
