Criterion Water Bath

water bath

The L-K Industries Criterion Water Bath Heater distributes 900 watts of heating power. The unit is designed to provide precise heating of solvents and 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 Criterion series uses water to transfer heat. The unit can accommodate two 1-gallon bottles of solvent, 14 Long Cone (C) centrifuge tubes, 14 Capillary (E) tubes or 12 Short Cone (D) style tubes. It is preprogrammed to a temperature set point of 140°F (60°C) and can maintain that set point with unrivaled precision. The Criterion Water Bath heater features digital temperature control, which allows for extended, consistent heating. The design enables efficient rotation of heated solvent samples and less down time due to optimal tube capacity. Its modular construction creates versatile options for lab configuration.

The unit is certified by ETL (Electrical Testing Laboratory) for Class I, Division 2, indoor use. It is rated for Group A, B, C and D Hazardous and Ordinary Locations (Pollution Degree 2). It meets the requirements of ANSI/ISA-STD 12.12.01 and 61010.1. Due to these certifications, the unit requires hard-wiring. In the fall of 2016, all Criterion water baths will feature a stainless steel tub, which reduces corrosion and makes the bath more robust.

TradeMark Heater

The L-K Industries Trademark Heater is a dry block unit built for use on a laboratory benchtop. Starting in the fall of 2016, all units will be certified for Class I, Division 2 locations and rated for 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 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.
