ABSTRACT:
A disposable cell for a diaphragm-actuated fluid-transfer control device, which comprises two cell walls peripherally joined to one another, of which at least one wall is flexible, and is adapted to be flexed from a first position, in which it is located in close proximity to the other wall, reducing the space enclosed between the two walls to a minimum, to at least a second position, in which at least some regions of the flexible wall have moved away from the other wall, thereby increasing the space between the two walls, and an inlet port and an outlet port provided in at least one of the walls. There is also described a combination of a disposable cell with a diaphragm-actuated fluid transfer control device.
