Recirculating chillers - Model F-305 | F-308 | F-314

Recirculating chillers - Model F-305 | F-308 | F-314 BÜCHI

The BUCHI recirculating chillers are meant to be used with laboratory equipment that requires coolant flow such as rotary evaporators, parallel evaporators, Kjeldahl- and extraction products. The F-300 line is specifically designed for seamless integration into a BUCHI Rotavapor® R-300 system. The temperature can conveniently be set by the interface. Furthermore, it offers ECO-mode, temperature lock and instant start with dynamic pressure adjustment without waiting until the chiller reaches its set temperature.

Main Features
Feature  Description   With interface 
Temperature setting on chiller 

Set the temperature in 0,1 °C increments using the navigation knob.

Actual and set temperature is shown on the integrated display. 

 
Temperature lock 

Lock the set temperature with a push of the navigation knob

to avoid unintentional changes. 

 
Remote control with interface 

In addition to the setting of the chiller, the temperature can conveniently

be set on the central interface thus showing all process parameters at a glance. 

Remote monitoring on smartphone  The Rotavapor® App for iOS, Android and Windows offers push notifications, live view and charting of all process parameters on smartphones. 
Dynamic operation  The destillation process can be started instantly when using the solvent library mode. While the chiller reaches its set temperature, the vacuum is dynamically adjusted. 
Automatic stop  The chiller can be configured to stop automatically when the distallation process is terminated. 
ECO-mode  Alternatively to the automatic stop the ECO-mode switches the chiller into a stand-by mode when not in use. The temperature increases by a definiable ÄT to be cooled down to the set temperature periodically (see graph below). 
* Only applicable when used in combination with Interface I-300 or I-300 Pro
