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.
