The Lauda (Brinkmann) Ecoline RE106 Refrigerated Circulating Bath is a versatile thermal control unit widely utilized in laboratories for applications requiring precise heating and cooling, such as rotary evaporation or reactor temperature control. The system is built around the E 100 Controller, a user-friendly digital head that features a bright LED display for simultaneous viewing of actual and setpoint temperatures. This controller utilizes PID feedback mechanisms to ensure high temperature stability (typically ±0.05°C), covering a broad operating range that generally spans from -20°C to 120°C, making it effective for both low-temperature organic synthesis and standard heating tasks. Physically, the unit integrates a 6-liter stainless steel bath, which provides ample volume for immersing small flasks or rack samples directly while maintaining a compact benchtop footprint. A critical feature of the RE 106 is its powerful pressure pump, designed not just for maintaining uniformity within the bath, but for driving thermal fluid through external closed loops. This allows the unit to act as a thermostat for external equipment, such as the condenser of a rotary evaporator or the jacket of a small reaction vessel. The "Brinkmann" branding confirms that this is a robust model known for longevity in research environments. Used; tested; excellent condition.
