This adjustable magnetic stirrer is ideally used with a magnetic stir bar.
Simply place your yeast propagation flask (Erlenmeyer Flask) on top of the stir plate and drop in the sanitised stir bar. Switch on the machine and adjust the spin speed to suit. Once a clearly visible vortex is created, this will increase aeration of the mix and increase the rate at which yeast cells will reproduce.
The 150W heater function is sufficient to thoroughly dissolve malts but should not be used once yeast is pitched unless the solution is below the ideal temperature for your yeast. Take care to monitor the starter temperature whilst warming.
Can take Erlenmeyer Flasks up to 5 litre capacity.
