Corning® Digital Stirring Hot Plates

Corning Stirring Hot Plate model PC-420 (EMS #72350) is replaced by our new Digital Stirring Hot Plate, model PC-420D, and model PC-620 (EMS #72349) is replaced by our new Digital Stirring Hot Plate, model PC-620D.

Corning® has now added innovative microprocessor technology into their units with digital display which optimally controles the heating and stirring to the 5" x 7" (12.7 x17.8cm and 10" x 10" (25.4 x 25.4 cm) Pyroceram glass-ceramic stirring hot plates.

Performance Features

• Closed-loop heating and stirring controls that monitor and regulate both temperature and stirring speed.
• Microprocessor maintains consistent and repeatable temperature setting from 25°C (if ambient temperature is 0°C or lower) up to 550°C.
• Digital LED temperature display is adjustable in 5°C increments and blinks until temperature is reached.
• Optional external temperature controller truly controls temperature inside the vessel and eliminates the need to closely monitor liquid temperature.
• Exclusive closed-loop stirring control monitors and regulates the stirring speed from 60 -1150 RPM for aqueous, viscous, or semi-solids solutions.
• Digital LED speed display gives you better control of your stirring process.
• Stronger, larger magnet improves stir bar coupling combined with automatic up speed adjustment minimizes decoupling.

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 will shut off unit when is not in liquid.
• Two piece casting design deflects spills away from electronic and includes a built in mount for an optional 18" (45.7 cm) support rod.
• UL and cUL approved.
