How low can you go?
The “KISS K6” is our most simple and economic refrigerated circulator. The picture shows it connected to a 1-litre Glass Jacketed reactor from Chemglass. The reactor contained 0.8-litres of Ethanol with the stirrer speed set to 150 RPM. Ethanol was also used as the heat Transfer fluid (HTF). As the display on the KISS K6 shows, this simple and cost-effective circulator cooled the reactor to -18.5°C.
