How To Choose Lab Equipment Laboratory Hotplates/Stirrers
Posted on:Tuesday, February 17, 2015

Original article on LabEquipmentDepot
Among the most required tools of the qualitative or quantitative laboratory are Hotplates, Stirrers and a combination of Hotplate/Stirrer. Usually these instruments are affordable, reliable and easy to use. A magnetic Hotplate/Stirrer uses a rotating magnetic field, that causes a stir bar to spin thereby mixing a solution. In the lab a container with the liquid to be stirred is placed on the ceramic or metal top (plate) of the Hotplate/Stirrer. The stirring speed and the desired temperature is selected either by a digital readout or with a manual knob on the instrument front panel and stirring and heating is begun. Temperatures from ambient (room) to 550 degrees C may be achieved and stirring speeds from 100 to 1500 rpm are possible.
