At micro and nano-scale liquid flow rates, calibration is critical, especially for applications such as volumetric dosing and drug delivery. In particular, for drugs with a very short half-life (in the order of one minute), or for drugs that require a very low blood concentration for toxicity reasons, such as vasoactive or anaesthetic drugs, the exact amount of volume administered as well as the stability of the flow rate are crucial.
Objectives
Establishment of an infrastructure for calibration of drug delivery systems for flows up to 10-100 nl/min
Development of transfer standards for on-site calibration of drug delivery equipment
Performance evaluation of drug delivery devices, dependence on operating conditions and clinical characteristics
Provision of a good practice guide for drug dispensing and improved calibration services for drug delivery devices
