The Thermo Scientific NESLAB RTE 7 Circulating Water Bath is designed to provide temperature control for applications requiring a fluid work area or pumping to an external system. Units consist of a non-CFC air-cooled refrigeration system, circulation pump, seamless stainless steel bath, work area cover, as well as a microprocessor temperature controller. This ensures both reliable and stable control of your liquid temperature procedures.

The RTE Series of refrigerated circulating baths feature powerful cooling and heating, expansive temperature ranges, and sophisticated controller technology, these robust
compact units offer the ultimate in temperature stability and reliability for either external circulation or in-bath applications.
An industrial-grade force and suction pump provides the pressure necessary to circulate fluid long distances to both open containers and closed loop systems. This gives you the flexibility to meet a wide range of application needs.
The Thermo Electron Neslab RTE 7 Circulating Water Bath provides excellent agitation for improved uniformity as well as stability. The SmartSense controller also ensures that your RTE system is performing at its peak.
