What is a Laboratory Hot Plate & Magnetic Stirrer?
Laboratory hot plates & Magnetic Stirrer consist of a heating element installed underneath a plate surface, manufactured from conductive steel or plastic, connected to a digital or analog controller.
What is a Laboratory Hot Plate & Magnetic Stirrer used for?
Ubiquitous in clinical, production and research labs, hot plates & Magnetic Stirrer are used to slowly and safely heat samples, reagents and chemicals without the dangers associated with the open flame of a Bunsen burner.
Stirring Hot Plate & Magnetic Stirrer Styles, Components, and Types
Stirrer hot plates are equipped with an overhead or magnetic stirring apparatus to mix the sample during the heating process, ensuring more complete temperature uniformity. For protection, hot plates & Magnetic Stirrer include several safeguards, including over-temperature prevention, audible and visual alarms, and non-sparking components for flammable or explosive samples.
Standard temperature control hot plates & Magnetic Stirrer includes a stirring apparatus for sample mixing during the heating process. Economical than stirring hot plates, standard hot stirrer plates are reliable workhorses requiring minimal maintenance and re-calibration routines.
Magnetic stirring hotplates contain an electromagnet, installed underneath the plate surface, which produces a rotating magnetic field across the plate. The magnetic field causes a stirring bar, immersed within the sample, to spin at a predefined speed (up to 2,500 rpm). Magnetic stirrers do not include a heating element.
Stirring hot plates contain both a stirring apparatus and heating element installed underneath the plate surface for even stirring as the sample heats. While stirring hot plates are more expensive than magnetic hot plate stirrer’s magnetic stirrers or standard hot plates, they provide better heating uniformity for high-volume (over 500 ml) and highly-viscous samples.
