The Corning 6795-620KIT digital stirring hot plate has a temperature range of ambient to 550 degrees C, a 10 x 10 inch white glass-ceramic top plate, and comes with an external temperature controller, two 9" support rods, and a stir bar retriever. The white glass-ceramic top plate (Pyroceram) provides fast heating and resistance to chemicals 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 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. The hot plate can hold a support rod for 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 gas-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.

Top Customer Reviews
First impressions: Overall, the unit is well built and packed nicely in the box. It features a large ceramic top, neutral-gray cast base, and easy-to-read red LED digital displays for stirring speed and temperature. The design is sleek and modern. It looks good in the lab. The AC cord is a heavy-duty Euro-style detachable three-prong cord, which I like, as the cord is easy to replace if needed. It is also consistent with the types of cords found on test and measurement equipment. This unit operates on 120VAC and can draw over 1.1KW at full temperature.
The Kit version of the PC-620D also includes a magnetic stirrer, 18" vertical support rod (it screws into the rear of the base), as well as an external probe-type temperature sensor. After comparing other models on the market, it was the external temperature sensor that sold me on this Corning model. There is a comparable Corning model in a smaller footprint that also supports this sensor, but I opted for the additional power and heating area.
For those not familiar with hot plates, the external sensor is very important to maintaining reasonable temperature control of the medium. Let me explain. On most hot plates, the temperature of the LED display is the spot temperature on the underside of the ceramic (or sometimes aluminum) substrate. In the case of ceramic, there is a substantial temperature gradient from the center to the edges.Read more ›
