Description:
<p><strong>Eurostar 20 Digital 15 L Laboratory Stirrer, 115V </strong> </p> <p>Laboratory stirrer designed for simple stirring tasks for quantities up to 15 l (H2O). It automatically adjusts the speed through microprocessor controlled technology within the speed range of 0/30 - 2000 rpm. Safety circuits installed ensures automatic cut-off in an anti-stall or overload conditions. </p> <p>Continuous comparison of shaft speed to desired speed is maintained and variations are adjusted automatically. This guarantees a constant speed even with changes in viscosities of the sample. </p> <p><strong>Features: </strong> </p> <ul><li>Digital speed display </li> <li>Infinitely adjustable speed </li> <li>Push-through agitator shafts </li> <li>Overload protection </li> <li>Short-term overload operation </li> <li>Slim casing </li> <li>Quiet operation </li> <li>Error code display </li> </ul>
