Instructions Fisher Isotemp Water Baths Congratulations on your new Fisher Isotemp Water Bath. Isotemp Water Baths offer the versatility needed to handle virtually any clinical laboratory procedure — incubation, inactivation, agglutination — as well as most serological, pharmaceutical, biomedical, and industrial procedures. These water baths are available with chamber capacities of 2, 5, 10, 20, and 28 liters. The 2 liter unit is available configured with either a standard or shallow chamber. Also, a dual chamber unit is available with 5 and 10 liter chambers, with independent controls for each. All units are available to operate from either 120 or 230 volts. The baths work equally well with water or bath oil as the medium. All models offer the same temperature ranges: ambient to 60°C without the supplied cover, and ambient to 100°C with the cover in place (within physical limitations). These baths are microprocessor controlled for precise temperatures and reliable, trouble-free operation. Dual thermostats — one controlling the set point temperature and the other operating as a safety — virtually eliminate the possibility of overheating. Although not designed to operate dry, the bath will not be damaged if it is allowed to run dry.

The cover also allows the water bath to reach higher temperatures. The hinged, seethrough gable cover features unique “fins” that keep hands away from hot vapors for easier, safer opening. The cover stays open at the 90° position or, because of its quickattach hinge, can be lifted off completely to accommodate large glassware. To avoid personal injury: • Do not use in the presence of flammable or combustible materials; fire or explosion may result. This device contains components which may ignite such materials. • Do not remove or modify the grounded power plug. Use only properly grounded outlets to avoid a shock hazard.
