The unit is in full working condition and is ready for immediate release. A Julabo ED bath is a laboratory circulating water bath system that combines a bath tank with an immersion circulator for controlled heating and circulation of liquids. These units are commonly used to maintain samples or materials at a stable, set temperature in a lab environment. Typical applications include temperature control of samples during incubation, testing, or reactions, material testing (e.g., plastics, metals), calibration of thermometers or thermal devices, and heat treatment in research and quality control contexts. E suggests an open bath with circulator mounted on a bridge — the immersion circulator sits on top of the bath tank and drives both heating and fluid movement. D designates the controller simplicity level (digital setpoint via keypad with PID temperature control).
