¡á ¿ëµµ(Applications) * For over forty years, Corning¢ç stirring hot plates with the glass-ceramic Pyroceram¢ç top have been a laboratory standard. * Now we've improved them by adding digital temperature and stirring speed displays. * A Model PC-420D is shown to the left with optional temperature controller and support rod (Cat. No. 440129). * Both of these products can be purchased separately or as part of an accessory kit (Cat. No. 6795KIT). * They are available in two top sizes: - PC-420D with a 5" x 7" (12.7 x 17.8cm) Pyroceram¢ç top - PC-620D with a 10" x 10" (25.4 x 25.4cm) Pyroceram¢ç top
¡áƯ ¡ (Features ) Performance Features: * Closed-loop heating and stirring controls that monitor and regulate both temperature and stirring speed. * Microprocessor maintains consistent and repeatable temperature settings from 5¡ÆC (if ambient temperature is 0¡ÆC or lower) up to 550¡ÆC. * Digital LED temperature display is adjustable in 5¡ÆC increments and blinks until set temperature is reached. * Optional external temperature controller (Cat. No. 6795PR) 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-solid solutions. * Digital LED speed display gives you better control of your stirring process. * Stronger, larger magnet improves stir bar coupling combined with automatic ramp up speed adjustment minimizes decoupling. * Operate on 100V/60Hz with standard three-prong plug for use in Japan and other areas with similar electrical requirements.
Safety Features * Bright LED HOT TOP icon lights up when top plate is over 60¡ÆC, even when heat control is turned off. * Separate temperature sensor provides power cutoff if unit overheats. * Optional temperature controller (Cat. No. 6795PR) will shut off unit when controller is not in liquid. * Two piece casting design deflects spills away from electronics and includes a built in mount for an optional 18" (45.7cm) support rod (Cat. No. 440129). * UL and cUL approved
Product Details * The flat, bright-white Pyroceram¢ç glass-ceramic top provides uniform heating and better contrast during applications that require monitoring of color changes. * Pyroceram¢ç tops are easy to clean and highly resistant to scratches, corrosion, and chemicals. * They can also be used at much higher temperatures (up to 550¡ÆC) and are less likely to corrode than metal tops. * The Pyroceram¢ç glass-ceramic material was originally developed by Corning for use in missile nosecones. * Because of its unique properties it was later used in Corningware¢ç kitchen products as well.
