Safe control of potentially explosive
mixtures
The EZ-2 Inert Purge unit from Genevac provides laboratory managers with a fail-safe tool to meet the requirements of the Atex directives relating to safe removal of solvent vapours
The EZ-2 solvent evaporator can safely remove most organic solvents without forming an explosive mixture of organic vapour and air, but for use with inflammable liquids such as diethyl ether or pentane it is now mandatory to use the EZ-2 Inert Purge unit The Inert Purge unit works by controlling the flow of nitrogen from a cylinder to the evaporation chamber and is interlocked with the EZ-2 operating system

Control of explosive mixtures in the workplace
Inert purge unit was developed to enable laboratories to comply with a new European Union law on the control of explosive mixtures in the workplace - the Atex directive
Flooding the chamber with nitrogen before evaporation commences removes the explosion risk entirely.
A run can only commence when the chamber has been purged to a pre-set over pressure, which is automatically detected by the EZ-2.
If this pressure is not reached, for example because the lid has not sealed properly or the drain valve has been left open, the EZ-2 fails safe and will not allow evaporation to commence.
In addition, the Inert Purge unit has an easy to read regulator indicating cylinder gas pressure and an interlock, which prevents purge commencing if the cylinder pressure is too low.
A key switch allows managers to dictate that purge must be used at all times if this is deemed necessary.
Taken together, this makes the new EZ-2 Inert Purge unit a valuable tool to help managers meet the requirements of the Atex directives in full and for any working solvent, says Genevac. Request a free brochure from Genevac ...
