Case Study: PRESTO W56 Process system

Heating up of an Büchiglas 100 l reactor from +20 °C to +150 °C with a PRESTO W56 Process system


This case study tests the heating capacity of the JULABO PRESTO W56 Process system with a 100 l glass reactor. The PRESTO W56 is connected to the reactor via two 2 m metal hoses. The PRESTO W56 Process system has been programmed to heat up from +20 °C to +150 °C.
