Clean and in near immaculate condition. This is the F25 with the EH head and comes with the tubed optional heat exchanger lid as shown.

Powered, ran quietly with all functions operating as designed. Menu operation was flawless, as was the fluid pumping systems.

Tested various setpoints for long periods to check control and accuracy. Heats quickly and maintains setpoint to within 0.1°. Cooling was initially a bit underpowered but improved immensely after refrigeration service. The only issue of note is the display which has 2 overly bright segments. This did not effect usability but does detract slightly from the immaculate appearance of the system. 

Hassle-free warranty.

Manufacturer Description 

F25-EH Refrigerated/Heating Circulator for internal and external temperature applications

JULABO Refrigerated & Heating Circulators for heating and cooling are suitable for external temperature tasks and for temperature applications directly in the bath. A model from three different series’ with different capacities can be selected. Powerful circulating pump systems and high heating and cooling capacities guarantee short heat-up and cool-down times. The inevitable dust accumulation that occurs in refrigeration systems is solved by means of an easily removed venting grill, which allows for easy cleaning. Depending on the model, the units are equipped with handles or castors for an easy transportation. All models have a drain tap on the front allowing the fluid to be drained easily. The compact assembly of each unit enables a space to be saved in the laboratory.
