Case Study: PRESTO A45t Process system

Heating up of an Asahi 20 l reactor from -20 °C to +20 °C with a PRESTO A45t Process system

Objective

This case study tests the heating capacity of the JULABO PRESTO A45t Process system with a 20 l glass reactor. The PRESTO A45t is connected to the reactor via two 2 m metal hoses. The PRESTO A45t Process system has been programmed to heat up from -20 °C to +20 °C.
