Safe Evaporation Under Inert Atmosphere

HT-12


Genevac announce HT Series 3 evaporators with Inert Gas Purge (IGP) option enable safe operation even when removing highly explosive solvents such as diethyl ether.

To eliminate these risks, the IGP system purges the air from the HT Series 3 evaporator using an inert gas prior to commencing the evaporation process. As the highest risk of explosion exists at the beginning of the evaporation, when there is a mixture of solvent vapour and oxygen in the evaporation chamber, the IGP may be ‘locked on’ ensuring all users are automatically protected by this facility.
 
The IGP option can also be useful where an inert atmosphere is required to help protect hygroscopic or oxygen sensitive samples at the end of the evaporation or concentration process. IGP controls gases entering the evaporator, therefore at the end of the evaporation process, instead of releasing the vacuum by letting air into the chamber, inert gas is introduced instead. The inert gas atmosphere in the HT Series 3 evaporator is maintained until the user opens the system to retrieve their samples.
