Case Study: PRESTO A45 Process system

Heating up of an Chemglas 20 l reactor from -10 °C to +20 °C with a PRESTO A45 Process system

Objective

This case study tests the heating capacity of the JULABO PRESTO A45 Process system with a 20 l glass reactor. The PRESTO A45 is connected to the reactor via two 2 in. metal hoses. The PRESTO A45 Process system has been programmed to heat up from -10 °C to +20 °C.
