Refrigerated - 4.5 Liter Heating Circulators - HighTech Series

Category Stirred/Circulating Baths Accessories
Manufacturer Julabo
Overview

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 grid, 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 space to be saved in the laboratory.

F25-HE Refrigerated/Heating Circulator - The powerful upper class unit for demanding applications.

F25-HL Refrigerated/Heating Circulator - Superior model for most demanding applications

    FAQ

    Do the Julabo HighTech Circulators have the capability to ramp up temperature over a set time period?

    The HighTech circulators can be programmed to ramp. The best way to accomplish this is to use the free version of Julabo's EasyTEMP software. EasyTEMP provides a PC interface to create a temperature profile which is much easier than programming directly circulator. The HighTech RS232 port enables connection to a PC using a null modem cable.
