Case Study: PRESTO W55 Process system
Cooling a Büchiglas 50 l reactor from +20 °C to lowest possible temperature with a PRESTO W55 Process system
Objective
This case study tests the lowest temperature of the JULABO PRESTO W55 Process system with a 50 l glass reactor. The PRESTO W55 is connected to the reactor via two 2 m metal hoses. The PRESTO W55 Process system cools from +20 °C to -52 °C maximum low temperature.
