Techne-water-bath, unheated baths are designed to accommodate a techne thermoregulator to control temperatures between -35°c to +200°c with ±0.01°c uniformity. sub-ambient temperatures are achieved with a techne dip or flow cooler. refrigerated baths are self-contained chilled liquid circulating systems for laboratory applications. temperatures between -35°c and +150°c are achieved with a techne .... The temperature control and life science equipment from techne include; calibration temperture, control heater, thermo-regulators, lab cooling products and waterbaths., fda 2400 requires a circulating water bath for butterfat and coliform test applications. the constant temperature controller features a powerful pressure circulating pump and a rugged, splash-proof case, with all submerged parts being made of either stainless steel or high-temperature plastic..
