<p><b>ABOUT MAGNETIC STIRRERS:</b></p> <p>This economical SH-2 model Magnetic Stirrer Hot Plate independently controls temperature and stirring speed. The 120 ×120mm Stirring Hot Plate has a 180W heating power and 716°F (380°C) maximum temperature. The magnetic stirrer is adjustable from 100 to 2000 rpm. A support stand with an adjustable thermometer holder is also included. Suitable for industrial, agricultural, medical and health, scientific research institutions, colleges and universities laboratory liquid mixing heating.  <br>Our SH-2 Magnetic Stirrer Hot Plate has a One Year Manufacturer Warranty.</p> <p><b>Specifications:</b></p> <p>Heating power: 180 watts</p> <p>Stirrer motor power: 10 watts</p> <p>Maximum heating plate temperature: 380°C</p> <p>Stirring speed: 100-2000 rpm adjustable</p> <p>Electricity voltage requirements:110V for US/CA/MEX</p> <p>Stirring capacity: 1000ml liquid (H2O) volume</p> <p>Heating plate dimensions: 120mm x 120mm</p> <p>Heating plate material: anodized aluminium</p> <p>Overall dimensions (LxWxH): 200mm x 120mm x 90mm</p> <p><b>Important reminder</b></p> <p>1.The control of heating power does not mean that temperature can be controlled (i.e. the temperature cannot be controlled). You need a thermometer to manually adjust heating operation if you intend to control the temperature.</p> <p>2.It's difficult to perform stirring and heating simultaneously for the stirrer with heating power at 180W only for the stirred liquid keeps losing heat. As a result, we suggest that stirring shall be stopped when heating is performed, or you can get boiling liquid by heating and stirring such liquid in a sealed container.</p> <p>3.If you want to get faster stirring speeds, there is a trim resistor at the bottom of the unit. You can use a screwdriver to fine-tune directly. (However, please exercise caution. It can easily cause the liquid to splash out, if the stirring speed is too fast.)</p>
