Aug 29, 2020 Vacuum lines usually have a better vacuum (10 -4 to 10 -7 torr) than Schlenk lines (10 -2 to 10 -4 torr), because vacuum lines typically have a diffusion pump. A way of delineating these would be to use the terms Schlenk line and High vacuum line. Vacuum lines usually connect to the experimental apparatus with joints, which provide a better ...

The dry running nXDS vacuum pumps should be operated with inert gas ballast to avoid condensation of vapours and dilute solvents entering the pump. C-versions should be used if slightly corrosive or aggressive gases/vapours are to be pumped. In addition, a cold trap which is often already part of the Schlenk Line, could further protect the pump.
