Multi-position (Hot Plate) Magnetic Stirrer LMMS-A21 is a space saving and economical unit with 10 heating/stirring position in a footprint. It is highly efficient and inputted by brushless type DC motor. Equipped with Stainless steel work plate, cover with silicone cushion, resistance to skid and corrosion. It reduces the over noise and its free from maintenance. Maximum stirring quantity in each stirring position is 0.4 L, the powerful magnets and motor give stirring speed up to 1100 rpm with the working temperature range from 5 to 40°C. Its heating temperature ranges from room temp. to 120°C and over protection temp. range is 140°C.
