Julabo CORIO CD-800F refrigerated circulator
The refrigerated circulator is ideal for demanding temperature control tasks in research facilities, laboratories and industrial processes. Its wide temperature range of -40 °C to +150 °C and high cooling capacity make it a reliable solution even for complex applications. At the same time, the device works with an environmentally friendly refrigerant, which contributes to long-term cost and energy savings. Similar compact solutions such as the [Julabo CORIO CP-300F refrigerated circulator] also offer stable temperature control, but this model impresses with its optimized design for a small footprint and outstanding performance at low temperatures.
Versatile performance features
The robust design and well thought-out concept make this thermostat particularly interesting for standardized processes in which constant and precise temperature conditions are required. Thanks to the integrated pressure pump, both internal and external applications can be easily implemented. In addition, the high-quality stainless steel design of the bath tank ensures a long service life and easy cleaning. The appliance works with class-compliant safety equipment in accordance with DIN 12876-1, classification III (FL), to ensure maximum operational safety.
Important features and values at a glance:
- Working temperature range: -40 °C to +150 °C
- Heating capacity: 2 kW
- Cooling capacity: up to 0.85 kW (at 20 °C)
- Filling volume: 5 to 7.5 liters
- Temperature stability: ±0.03 °C
- Pump capacity: 15 l/min at 0.35 bar
- USB interface for convenient control and evaluation
- Natural refrigerant solution with extremely low global warming potential (R1270)
The thermostat also scores points with an LED display that shows the temperature values in an easy-to-read format. The resolution of the display is between 0.01 and 0.1 °C, which is particularly important for sensitive processes. The integrated drain cock and the removable ventilation grille facilitate maintenance work in the laboratory. The user can flexibly adapt the application to the respective setup using the switch function between internal and external circulation. In addition, tube olives for 8 mm and 12 mm internal diameters enable individual connection to external systems.
The use of a natural and energy-efficient refrigerant (filling weight 85 g, GWP value 2) contributes to resource-saving operation. With an output of 0.11 kW at -40 °C, the appliance can also handle low-temperature applications, which are important in pharmaceutical process development, for example. Its compact design (33 x 47 x 70 cm) and weight of around 42 kg allow for flexible installation - especially if space in the laboratory is limited.

Frequently asked questions (FAQs)
How easy is it to switch between internal and external temperature control?
An easily accessible changeover switch makes it possible to switch quickly without additional tools. This makes it easier to adapt to different test setups.
Which maintenance steps are particularly important?
Regularly checking the refrigerant pressure and cleaning or replacing the ventilation grille are the most important maintenance steps. The bath should also be cleaned at defined intervals and checked for fill level.
Is it easy to connect to digital systems?
Yes, temperature profiles can be recorded and controlled via the integrated USB interface. This enables seamless integration into laboratory information and management systems.
Which liquids are recommended for operation
Depending on the application, glycol-water mixtures, ethanol or special thermal oils are common. It is important that the maximum viscosity of 50 cSt is not exceeded.
How is the temperature accuracy ensured?
The PID control with a resolution of up to 0.01 °C guarantees extremely precise control. If necessary, additional adjustments can be made via 1-point calibration.
