Abstract: A rotary valve comprising a stator with an inner stator face, and a rotor with an inner rotor face arranged in sealing contact with the inner stator face, the rotor is rotatably movable to a plurality of rotor positions about a rotational axis relative to the inner stator face, the stator comprises a plurality of connection ports each being in fluidic contact with a corresponding valve orifice at the inner stator face and the rotor comprises two or more interconnection paths for selective fluidic interconnection of said valve orifices with respect to the rotor position.

Abstract: A rotary valve for selectively connecting at least one component (51, 52) into a fluid path. According to the invention the inner stator face (111a, 211a) comprises orifices (131b-136b; 231b-236b) and said inner rotor face (112a, 212a) comprises at least a first groove (121, 221), a second groove (122, 222), and a third groove (123, 223) so arranged that the rotary valve can take at least three different rotary positions, in which either both components are bypassed, only one of the components is connected and the other bypassed or both components are connected to a main flow.

Abstract: A connector is provided for selectively coupling one or more lines or wires (19?, 19?) to a receiving and/or transporting device (27). The connector comprises at least one line or wire receiving ferrule (7) having a plurality of line and/or wire receiving holes (17?-17?) each capable of receiving one of said one or more lines or wires (19?, 19?), wherein said connector further comprises a body (3) for receiving said ferrule (7) and clamping means (9, 11) for exerting a force on said ferrule (7) in order to simultaneously exert a line or wire clamping force on all said line and/or wire receiving holes (17?-17?). In this way all the fluid lines or wires can be clamped at the same time.

Abstract: The present invention relates to valves with small dead volumes. A valve in accordance with the present invention has a ferrule (7) which receives a plurality of fluid lines (33) which lead to outlets on an end surface (25) of said ferrule (7) and a movable selector body (15) which has a fluid groove (37, 37A) on a surface (23) which is in contact with the end surface (25) of said ferrule (7). Means are provided for exerting a clamping force on said ferrule (7) in order to simultaneously clamp all the fluid lines (33).

Abstract: In connection with a method for determination of the content of at least some substance which is solved in a liquid, is used a measuring device, which is arranged to detect the character of a physical magnitude of the liquid, which physical magnitude is related to the content of the present substance, when the liquid has been treated with an adequate reagent. A volume of the reagent is measured, which volume corresponds to a defined length of a line, in which the reagent is transported, whereafter the measured volume is incorporated in a closed loop (1) in which the measuring device (26) is included, whereby the reagent volume which is incorporated in the measuring loop initially is essentially unmixed with the sample liquid and forms a section (X) in the line of the loop, which for the rest is filled with sample liquid and whereby the length of said section corresponds to or is in direct proportion to said length of the line in which the reagent is transported before it is incorporated into the loop.
