Corning Stirrer Hot Plate
Corning® Stirring Hot Plates

|
| Figure 1. Corning® stirring hot plates (Model PC-420D shown) can regulate temperatures up to 550°C while stirring at speeds up to 1150 RPM. | |
 |
|
| Figure 2. The PC-220 stirring hot plate offers a 4″ x 5″ (10.2 x 12.7cm) Pyroceram® top and closed-loop stirring for consistent and accurate speed. It gets the job done quickly, efficiently, and safely. | |

For over forty years, Corning’s stirring hot plates with Pyroceram® glass-ceramic tops have been a laboratory standard. Now we’ve improved them by adding optional digital temperature and stirring speed displays.
New digital display Pyroceram® top stirring hot plates (Figure 1) are available in two top sizes:
- PC-420D with a 5″ x 7″ (12.7 x 17.8cm) Pyroceram® top
- PC-620D with a 10″ x 10″ (25.4 x 25.4cm) Pyroceram® top
A standard Pyroceram® top stirring hot plate is available in one size:
- PC-220 with a 4″ x 5″ (10.2 x 12.7cm) Pyroceram®top (Figure 2)
New Digital Stirring Hot Plates offer:
- Digital LED temperature display is adjustable in 5°C increments that blinks until set temperature is reached.
- Digital LED speed display gives you better control of your stirring process.
- Microprocessor maintains consistent and repeatable temperature settings from 5°C (if ambient temperature is 0°C or lower) up to 550°C.
- Exclusive closed-loop stirring control monitors and regulates the stirring speed for aqueous, viscous, or semi-solid solutions.
- Automatic ramp up speed adjustment minimizes decoupling.
- Optional external temperature controller (Figure 3; Cat. No. 6795PR) truly controls temperature inside the vessel and eliminates need to closely monitor liquid temperature.
New Digital Stirring Hot Plate Safety Features:
- Bright LED HOT TOP icon lights up when top plate is over 60°C, even when heat control is turned off.
- Optional temperature controller (Figure 3; Cat. No. 6795PR) will shut off unit when controller is not in liquid.
All Corning® Stirring Hot Plates have:
- Low-Profile design that uses less space on bench tops and under hoods.
- Two piece casting design deflects spills away from electronics and includes a built in support rod mount.
- Hot top indicator light blinks a warning if the top is too hot to touch (>60°C; 140°F) – even when the unit is turned off.
- 2 year warranty
- Extra-large knobs with easy-to-read numbers provide better control, even while wearing bulky safety gloves.
- Choice of three voltages to meet power requirements globally (see Ordering Information below).
