• Kit includes digital stirring hot plate and external temperature controller, two 9-inch support rods, and a stir bar retriever.
• Plate temperature range of ambient to 550 degrees C is adjustable in 5-degree increments.
• White glass-ceramic top plate for fast heating and resistance to s and scratches.
• Dual LED readouts display temperature and speed settings.
• Speed range of 60 to 1,150 rpm in increments of 5, 10, 20, or 50 rpm.

The Corning 6795-420KIT PC-420D digital stirring hot plate has a temperature range of ambient to 550 degrees C, a 5 x 7 inch white glass-ceramic top plate, and comes with an external temperature controller, two 9-inch support rods, and a stir bar retriever. The white glass-ceramic top plate (Pyroceram) provides fast heating and resistance to s and scratches. It has dual LED readouts to display temperature and speed settings. Its temperature control knob adjusts temperature in 5-degree increments. The external temperature controller helps ensure regulation to + or - 2 degrees C. This hot plate has a stirring speed range of 60 to 1,150 rpm in increments of 5, 10, 20, or 50 rpm, depending on the speed setting, and it regulates the stirring speed for aqueous, viscous, or semi-solid solutions. Stirring control slowly increases speed for improved safety and enhanced coupling with the stir bar (sold separately). For safety, a hot top light indicates when the unit is over 60 degrees C, even when the power is off. It can hold a support rod for holding the external temperature controller. This 120V stirring hot plate is used to heat glassware and heat and mix liquid solutions for scientific applications.

Laboratory hot plates are electric or -fired benchtop appliances that are used to heat glassware or its liquid or solid contents. Stirring hot plates can stir a liquid solution by means of a stir bar that is spun magnetically inside the vessel holding the solution. Hot plates are commonly used in scientific research, clinics, and classrooms. Corning manufactures consumable glass, ceramics, and plastic laboratory tools under the brands Corning, Costar, Cellgro, Pyrex, Axygen, Gosselin, and Lambda, among others. The company, founded in 1908, is headquartered in New York, NY.
