Methods A series of replicate solutions were dispensed using the SMART-FILL® Dispensing System. In each case the accuracy of the volume was determined (i.e. how close the measured value is to the actual requested volume) as well as the precision across multiple replicates of the same volume (i.e. repeatability of the dispensing process). Furthermore, since the Dispensing System has the capability to prepare both radioactive liquid and capsules, both of these process were examined by dispensing samples of known volume in two different ways, namely in glass vials and in phosphate-filled capsules. Results In general, the precision or repeatability of the dispensing volume using the SMART-FILL® System was very good. The relative standard deviation (i.e. RSD) for both experiments was below 5% for samples greater than 15 µL. When dispensing volumes of approximately 5 µL, the error in the measurement is between 10-15% but for even smaller volumes (i.e. 2 µL) the uncertainty increases to greater than 20%. When dispensing capsules in the range of 2-220µL, the relative error in the measurement is less than 5%. Conclusions The SMART-FILL® Dispensing System dispenses accurate volumes with good precision in the range of 15-220 µL. In this range, the relative standard deviation, which represents the uncertainty in a measurement, is below 5%.
