    Abstract: Disclosed are capsule/tube connector/tube assemblies that eliminate a connection point in a filter capsule apparatus. A relatively soft tube is thermally or sonically bonded to a relatively hard tube connector that may have a tube receiving bore, a frustoconical tube receiving channel or a straight tube receiving channel. The tube connector is bonded to a filter capsule port. The manufacturing process can be either a one-step process bonding the tube and capsule during formation of the tube connector in one step, or a two-step process that binds the tube to the tube connector in one step and binds the tube connector to a filter capsule port in a second step. Single and dual-walled tubes may be used as well as single and dual-walled tubes having reinforcing material superposed about or embedded in the tube wall(s). A tube support collar is also disclosed. Also disclosed are capsule port/tube connector/tube combinations in which capsule port tips and tube connectors are combined to create tube-receiving gaps or channels to secure a tube to a capsule assembly. Multiple capsule/tube connector/tube assemblies may be connected to form a filter train.

    Abstract: A valve comprising: a valve body; and a valve stem disposed at least partially within the valve body, the valve stem comprising a sidewall defining a central lumen and at least one opening in the sidewall, wherein the valve is adapted to prevent fluid flow through the lumen when the at least one opening is disposed within the valve body and permit fluid flow through the lumen when the at least one opening is exposed from the valve body, and wherein the valve is essentially free of a spring.
