The ESP is an ultraflat magnetic stirrer with no moving mechanical components, it is therefore maintenance-free. The stirring system consists of coils that induce a rotating magnetic field. A gentle start-up ensures optimum progression of the stirring speed whilst its modern, ergonomic structure is made of materials that ensure a high resistance to chemical reagents. Electronic speed regulation: up to 1100 rpm Stirring volume (H2O): up to 5 L
