MICRO FLOW FACILITY FOR TRACEABILITY IN STEADY AND PULSATING FLOW

Hugo Bissig, Martin Tschannen, Marc de Huu

Abstract

Micro and nano flow calibrations are important in several medical applications such as drug delivery where the knowledge of the exact amount of the delivered drug is crucial for efficient health care treatment and safety of the patient. However, international traceability in the micro and nano flow is not validated up to date for flow rate ranges below 33 μl/min. METAS develops in the framework of the EMRP project “HLT07 Metrology for Drug Delivery” a primary standard to cover the flow rate range from 1 ml/min down to 100 nl/min. The setup of the facility and the working principle are addressed in this paper.
