Distillation coolant pump

thingiverse

This tiny liquid chiller is built for distillation work in laboratories. A standard twenty millimeter, five-volt DC toy motor powers its simple pump system. The unit moves liquid through two meters of lab tubing to keep glassware cool, situated a half meter up from the pump, when using six-volt power supply - or one meter high with eight volts supply. The motor itself is carefully placed above an icy cold bath, which prevents heating up the coolant, an essential requirement for efficient liquid cooling systems.
