Abstract
The invention relates to a method of conveying liquid materials in closed systems without mutual contamination, comprising flushing the conduit with an inert gas between introduction of the materials into said conduit and using a peristaltic pump for introducing said materials, in which after each flushing operation for a moment said pump is made to rotate in the reverse direction. The invention further relates to a method for the automated elution of a radionuclide generator and delivery of a radiopharmaceutical liquid, in particular a Tc99m-pertechnetate solution, whereas said above method is used, and to a device for performing said method for elution and delivery of a radiopharmaceutical liquid.
