A pressure gauge and/or relief valve which may be used in a single-use fluid system, such as a sterilizable fluid system. The pressure gauge and/or pressure relief valve may be configured to measure and to relieve fluid within a fluid-containing structure, the pressure gauge relief valve including a housing having a first end, a second end, and an inner surface defining a passage between the first end and the second end, a movable element movable within the passage, wherein the housing first end is configured to be coupled with a fluid-containing structure, the housing second end is spaced from the housing first end; and the movable element is movable with respect to the housing to indicate pressure therein and to allow fluid to pass between the movable element and the inner surface of the passage at a selected pressure.

A method of making and loading a chromatography column includes selecting a column tube having an appropriate elasticity, and inner diameter and length, selecting appropriately sized flow distributors, a second flow distributor having a diameter that is larger than the inner diameter of the tube, permanently securing a first flow distributor to a first end of the tube, loading packing medium into the tube, inserting the second flow distributor into a second end of the tube to drive the second flow distributor into the tube to form a sealed chamber within the tube, adjusting the longitudinal position of the second flow distributor within the tube by applying a force to the second flow distributor until it reaches a desired location within the tube, and/or forcing liquid into the chamber to move the second flow distributor and permanently securing the properly positioned second flow distributor within the tube.
