The L-K Industries Trademark Heater is a dry block unit built for use on a laboratory benchtop. All units are certified for Class I, Division 2 Groups A, B, C and D Hazardous and Ordinary Locations. Due to these certifications, the unit requires hard-wiring. The unit is designed to provide precise heating of solvents and crude oil samples prior to use in a centrifuge or other equipment. It has a resistive heating element with RTD temperature feedback to a temperature controller. The resistive heating element is controlled by a solid-state relay. This allows the temperature controller to fail “OFF” if a signal is lost and prevents runaway heating. The TradeMark series uses aluminum to transfer heat to glass centrifuge tubes. It is offered in 110 or 220VAC and available in finger (A), pear-shaped (B), long cone (C) or short cone (D) style tube configurations. The digital programmable temperature controller regulates the temperature and is adjustable from 72°F to 250°F. This allows versatility for use in multiple applications. It features an insulated body to minimize heat loss and heat up the unit more efficiently. The dry bath helps prevent corrosion.
