4.3.2 Vaccum routing

General memory aid for vacuum routing

Independent of the installed glassware setup the vacuum pump has to be connected at the end of

the cooling path. Depending on the used setup this can either be subsequently at or after the last

condenser.

Example 1:

Vapor temp. sensor

End of cooling path

Connection to vacuum source

Connection to vacuum controller

Vapor path

NOTE

In case the Rotavapor is not equipped with a vacuum controller a blind cap must be used to close

the vacuum controller connector to achieve a tight setup. The vapor temperature sensor always has

to be installed before the vapor inlet of the ﬁrst condenser.
