We offer a single channel laboratory syringe pump which offers better precision. Multi-syringe accessories considerably degrade the precision of delivery and produce flow fluctuations, also in immediate flow rate. This is inevitable, because syringes have dimensional tolerances on the diameter, but also the mechanical resistances in each syringe vary from position to position. The relative force effects adapt to these resistances and, in addition to the dimension tolerance on the syringe diameter, produce flow variations.
