Determining Optimal Gas Flow in an N-EVAP Nitrogen Evaporator

Determining Optimal Gas Flow in an N-EVAP Nitrogen Evaporator

As stated earlier, at a given temperature the optimal gas flow may be defined as the highest velocity at which the gas jet can impinge on the solvent surface without causing excessive turbulence. This being the case there are in essence two potential operational modes (1) a uniform operational mode in which all of the sample vials are identical and all of the samples are

How to Backfill Your System with Inert Gas [Flowchart]

Connect the three-way valve to the vacuum system; utilize vacuum/pressure-safe hose line. To backfill with nitrogen/inert gas, the system must be closed and under vacuum; once setup is assembled and sealed, pull vacuum via the vacuum system. With the inert gas flow regulator closed, open the three-way valve to the inert gas source.
