This dispenser provides for repetitive delivery of preset microliter volumes. To operate, simply insert a disposable syringe into the dispenser housing and raise the piston rod to fill. Volumes are quickly and easily selected by rotating the volume indicator knob to the desired setting; the corresponding number of repetitions is also shown as a function of volume. The volume indicator knob is color coded to match the syringes. Three sizes of disposable syringes are available to effect a total delivery capability of 10 µL to 5000 µL. Accuracy and reproducibility is better than ±1%.
