Case Study: PRESTO W91tt Process system

Heating up of an Büchiglas 100 l reactor from -50 °C to +20 °C with a PRESTO W91tt Process system

Objective

This case study tests the heating capacity of the JULABO PRESTO W91tt Process system with a 100 l glass reactor. The PRESTO W91tt is connected to the reactor via two 2 m metal hoses. The PRESTO W91tt Process system has been programmed to heat up from -50 °C to +20 °C.
