Abstract: This disclosure relates generally to a containment system for containing a fluid. More specifically, the disclosure relates to a fitment for attaching a liner within a container and providing a fluid path from the liner to an outside of the containment system. The liner and at least a part of the fitment provide the wetted surfaces for the containment system, while the fitment has a portion that can be joined to an outer container that, for example, provides rigidity and light protection. The fitment may be a two-piece fitment with a liner fitment to which the liner may be joined, and a retainer that may be joined to a container, where the liner fitment and the retainer are joined to one another, for example by a mechanical connection. The liner and liner fitment may be fluoropolymers or other non-reactive polymers. The container and retainer may be UV-blocking polymers.

Abstract: A removable filter cartridge includes a filter housing containing a filter, a sealing valve coupled to an open end of the filter housing and configured to removably couple the removable filter cartridge to a filter head.
