Corning 6796-620D Stirrer and Hot Plate, never been used, UK version, cord and plugs missing. The Corning® PC-620D stirring hot plate has a 10 x 10 (25.4 x 25.4cm) Pyroceram® top and digital temperature and stirring speed displays. It is designed to operate on 230V/50Hz with either the BS 1363A or CEE7-7 plug for use in parts of Europe, Asia, Africa, Australia and other areas with similar electrical requirements. Microprocessor maintains consistent and repeatable temperature settings from 5°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 set temperature is reached. Exclusive closed-loop stirring control monitors and regulates the stirring speed from 60-1150 RPM for aqueous, viscous, or semi-solid solutions. Stronger, larger magnet improves stir bar coupling combined with automatic ramp up speed adjustment minimizes decoupling.
