Case Study: PRESTO W50 Process system

Heating up of an QVF 50 l reactor from +20 °C to +150 °C with a PRESTO W50 Process system


This case study tests the heating capacity of the JULABO PRESTO W50 Process system with a 50 l glass reactor. The PRESTO W50 is connected to the reactor via two 2 m metal hoses. The PRESTO W50 Process system has been programmed to heat up from +20 °C to +150 °C.
