Abstract: A sorbent tube holder (100) for securing a sorbent tube (10) in position in a fluid-flow system, the sorbent tube holder (100) comprising: an mounting element (126) having first and second opposed ends (126a, 126b) which define a tube mounting axis (A-A); at least one fastener (128) in communication with the mounting element (126) for providing a releasable tube retaining force; at least one sorbent tube (10) engaged with the mounting element (126); and a holder frame (130) to which the mounting element (126) is attached to prevent or limit movement of the mounting element (126) perpendicular to the tube mounting axis. A method of preventing or limiting unintentional damage to a sorbent tube, and a portable tube holder are also provided.

Abstract: A fluid container (10) for fluid containment. The internal surface of the container body (12) defines a fluid-containment chamber (14), which has at least one fluid inlet and/or outlet port (18). Associated with at least one fluid inlet and/or outlet port (18), there is a fluid-flow control device, having a control body (16) integrally formed with the container body (12) as one piece.
