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.
• Separate temperature sensor provides power cutoff if unit overheats.
• 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).
