Case Study: PRESTO A80t Process system

Cooling a Chemglas 20 l reactor from +20 °C to lowest possible temperature with a PRESTO A80t Process system

Objective

This case study tests the lowest temperature of the JULABO PRESTO A80t Process system with a 20 l glass reactor. The PRESTO A80t is connected to the reactor via two 1 m metal hoses. The PRESTO A80t Process system cools from +20 °C to -70 °C maximum low temperature.
