Heating Stir Plate
This Advanced Magnetic Stir Plate has the great advantage of having an integrated thermometer so you can set what temperature you desire your liquid/yeast starter to be at. For more viscous liquids (oils) these unit should only be used with 1000mls, for the likes of yeast starters, and when using a larger stir bar these units can deal with up to 3000mls.
It has variable speed by a dial.
Speed range: 0-2600 rpm
Heating power: 400w
