The New Era Syringe Systems, Inc. syringe pumps are remarkable. They are perfect for grade-level 9-12, laboratory-course teachers who wish to add STEM chemical-engineering experiments. Large-scale chemical systems – e.g., oil refineries and chemical plants – are flow systems. In contrast, laboratory, small-scale chemical systems – usually round-bottom flasks – are batch systems.
The value of a syringe pump is its enormous range of flow rates – as much as one-million to one -- which depend upon both the inner diameter of the syringe used and the syringe-flow-rate setting.
A syringe pump allows the measurement of residence times and also the reaction kinetics of fixed-bed, tubular reactors.
Chemistry students should understand the difference between “flow” and “batch”. Both are STEM concepts.
