Abstract: A pneumatic device for holding and moving an elongate object, includes an annular hollow body through which the object passes and which is composed of two end parts forming jaws and a median segment connecting the two jaws to each other, with ease of movement of one with respect to the other under the effect of a controlled deformation of at least one portion of the median segment, where the various parts of the hollow body define respective chambers, the jaws have elastically deformable internal membranes, in the chambers of the two end parts are in fluidic communication with the chamber of the median segment, in each case by way of at least one respective calibrated flow element, the injection of pressurized gaseous fluid being effected by way of a single feed line.

Abstract: A device for selectively grasping a part of a separate elongated body extending through the device, includes at least three partially mobile jaw members defining between them a through hole of variable diameter depending on their mutual relative positioning, supporting and driving elements to which the jaw members are mounted and which are adapted to provide a coordinated motion to the members around the elongated body situated in the variable through hole, resulting in a closing or opening of the through hole. The jaw members have an elongated shape with two opposed ends and the supporting and driving elements include a circular or annular support body to which a first end of each jaw member is connected and a mobile annular driving body to which a second opposed end of each jaw member is connected.

Abstract: Ion-selective sensor (6) comprising a micro-machined chip with an analyte micro-channel (2), adapted to draw an analyte solution and a first liquid membrane micro channel (3) adapted to draw a liquid membrane solution, and an first electrolyte micro channel (1), adapted to draw an analyte solution. The ion-selective sensor (6) comprises a first substrate (100) and a second substrate (200) comprising each a structured surface to form, after assembly of said substrates the analyte micro-channel (2), the first electrolyte micro channel (1) and the first liquid membrane micro channel (3), each provided with their respective inlet and outlet.
