Genevac evaporators are robust systems designed to be resistant to the most common solvents and acids used within the chemistry laboratory, including TFA, DCM (methylene chloride), and DMSO.
For laboratories who wish to use strong acid chlorides, special models of Genevac systems exist which are specifically designed to be resistant to these highly corrosive acids. Some manufacturers claim that their unmodified systems are resistant to HCl, however the experience of Genevac engineers shows that to be truly suitable for routine evaporation of acid chlorides special resistant materials such as Hastelloy® and PTFE must be used in place of materials which would suffer from HCl attack. Materials such as these are used in Genevac HCl resistant systems.
Genevac HCl resistant systems must be used in conjunction with suitable vapour handlingand/or neutralising apparatus. Despite the efficiency of Genevac condensers HCl vapour does pass through the system and must be ducted safely away. HCl cannot be used in any Genevac system other than those specifically designed for the purpose.
HCl resistant systems are designed for use with high concentrations (e.g. 6N) of HCl and Thionyl Chloride. HCl resistant versions of the HT-4X, HT-12 and EZ-2 evaporators are available. The third generation EZ-2 Plus, HCl resistant, is also able to evaporate samples containing concentrated Nitric Acid - only this model EZ-2 can do this, please do not try to evaporate Nitric Acid in any other Genevac system. If you are not sure of the compatibility of your system for any acid or solvent, please contact Genevac before using it in your system.
