METHOD FOR MAKING A CHOICE OF LIQUID WHEN LIQUID DELIVERY IN ANALYZER AND SAMPLING DEVICE

摘要

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.
