Method and arrangement for levelling out tension variation of an optical

A valve system, applicable for instance to analyzers, consists of a plurality of electromagnetically operating clamp valves, purposed to unclamp and/or clamp an elastic tube passing through the valve, thereby respectively turning on or shutting off fluid flow in said tube. The apparatus comprises a magnet table carrying a plurality of electromagnets, a cover part adjacent the magnet table carrying closing pegs movable with the aid of the electromagnets, and a tube cassette between the magnet table and the cover part, in which cassette the tubes may be disposed in a given array for the functions of the analyzer.

A procedure for implementing the liquid selection of analyzer liquid dispension, includes the steps of selecting a liquid vessel from among a plurality of such vessels, and taking liquid into the dispensing system for further treatment. The liquid path from the liquid vessel that has been selected is so connected to the dispensing unit that (i) the sealing surfaces constituting the connection do not substantially slide against one another and that (ii) sealing at the connection is accomplished by means of elastic deformation of at least one of the bodies being coupled.
