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.

A disposable cell for mounting inside a diaphragm-actuated, positive-suction and expulsion fluid-transfer control device having a split housing comprised of two substantially contiguous halves with said cell being clamped at its periphery between a peripheral zone of one half of said split housing and a peripheral zone of said diaphragm, comprising: two cell walls permanently and fluid-tightly joined to one another at their periphery, both of which walls are flexible, one of said walls being adapted to be flexed from a first position, in which it is located in close proximity to the other wall, reducing the space enclosed by said two walls, to at least a second position, in which at least some regions of said one wall have moved away from said other wall, thereby increasing said space between said two walls, and an inlet port and an outlet port provided in at least one of said walls, wherein in the mounted and operative state of said disposable cell, the walls thereof constitute an impervious lining of one half of said split housing on the one end, and of said diaphragm on the other.
