Case Study: PRESTO W92tt Process system
Cooling a Büchiglas 100 l reactor from +20 °C to lowest possible temperature with a PRESTO W92tt Process system
Objective
This case study tests the lowest temperature of the JULABO PRESTO W92tt Process system with a 100 l glass reactor. The PRESTO W92tt is connected to the reactor via two 3 m metal hoses. The PRESTO W92tt Process system cools from +20 °C to -91 °C maximum low temperature.
