A vacuum chamber (2) for a direct air capture process and enclosing an interior space (13) for housing an adsorber structure (1) is given comprising a contiguous circumferential wall structure (115) along an axis (15), which circumferential wall structure (115) in an axial direction is closed by an inlet and an outlet axial wall (116), respectively, both axial walls (116) comprising at least one closing stainless steel lid (6) allowing for, in an open position, gas to be circulated through the vacuum chamber (2) for passing an adsorber structure (1), and, in a closed position, to close the interior space (13) and to allow evacuation of the interior space (13) down to pressure of 500 mbar.sub.abs or less.

Disclosed are a linkage control device and a blood gas analyzer adopting the linkage control device. The linkage control device comprises a power unit and a rotating component (4) provided with bosses (41, 42). The power unit generates power to drive the rotating component (4) to rotate. The linkage control device further comprises valve components (5, 6, 7, 8), a signal control unit, sensing switches, and sensing pins (43, 44, 45, 46). The valve components (5, 6, 7, 8) are matched with the bosses (41, 42) of the rotating component (4) in a pushing manner. The signal control unit controls the start or stop of the power unit. The sensing switches are connected to the signal control unit via signals. The sensing pins (43, 44, 45, 46) are arranged in pair with the sensing switches and are arranged on the rotating component (4).

Disclosed herein are embodiments of a valve assembly for preventing dead leg spaces in a container or tubing, the embodiments including a three-way valve system for controlling back-pressure in a fluid generating device, such as a single-use high pressure bioreactor. Also disclosed is a pressurized reactor system for bioprocessing, comprising a single-use container including a flexible wall or a semi-rigid wall.

A closure assembly for a fluid port having a fluid flow channel defined along an axis, the channel ending in a port opening. The assembly includes: a closure cap extending in a first plane arranged to seat across, and close the port opening, in use, in a closed state, a guide arm extending from the cap in a second plane substantially perpendicular to the first plane; a lifting guide to accommodate and retain the guide arm for movement of the guide arm in the second plane as the cap moves axially away from the opening; and a pivot mechanism between the guide arm and the lifting guide about which the cap is able to pivot relative to the lifting guide to an open position.

The invention relates to a drain comprising: a body having at least one fluid intake opening and at least one fluid discharge opening, a valve provided with at least one lug, and a disengagement device comprising: a fixed guide, able to be mounted so as to be fixed with respect to a body, a movable guide, comprising at least one housing for receiving the lug, the fixed guide and/or the movable guide comprising at least one projection and/or at least one recess, in particular having a shape complementary to the projection, and pressure spring, able to bias the movable guide against the fixed guide so that the projection cooperates with the recess.

A fluid control valve is disclosed, comprising: a valve body defining an outer wall for a curved flow path through the fluid control valve; and a valve element defining an opposing inner wall and rotatable relative to the valve body about a pivot point through between a closed position a range of open positions. A separation between the first inner wall and the outer wall along a restrictor portion of the flow path varies between open positions. The first inner wall and the outer wall are cooperatively defined so that for at least some open positions the separation between the first inner wall and the outer wall is constant along the respective restrictor portion of the flow path.
