New Benchtop Evaporator Removes Even Highest Boiling Point Solvents

Genevac has launched the EZ-2 Elite - a new addition to its popular EZ-2 evaporator range. The EZ-2 Elite is designed to remove high boiling point solvents and deliver enhanced solvent recovery thereby improving final drying of stubborn samples and enabling fast lyophilisation of HPLC fractions. The high performance scroll pump used with the EZ-2 Elite delivers deeper vacuum than the diaphragm pumps used on other EZ-2 systems. This advance plus internal enhancements to heat vapour duct and system components enable the EZ-2 Elite to routinely evaporate challenging high boiling solvents including DMSO and NMP. In addition these enhancements ensure that such challenging  solvents only condense in the SpeedTrap, and not anywhere else.

The SpeedTrap™ on the EZ-2 Elite works just like the other EZ-2 models but with the added benefit of automatic defrost and drain technology. The EZ-2 controls the SpeedTrap and the new Elite solvent collection vessel to allow mid-method defrosting and draining. This controlled draining facility enables very high levels of solvent recovery to be achieved. For example, when working with HPLC fractions, higher levels of dryness can be achieved by first draining the volatile organic solvent before tackling the water, allowing full vacuum to be used during final drying. Using the EZ-2 Elite SpeedTrap - the Genevac LyoSpeed™ method of fast lyophilisation of HPLC fractions is possible for the first time on an EZ-2 Evaporator.

Running the EZ-2 Elite is as simple as 1, 2, 3. Just load samples, select maximum safe temperature for samples, select solvent type and hit start. Offering true unattended operation capability the EZ-2 Elite requires no user training, even a beginner can competently use the system within 5 minutes. The EZ-2 Elite has been designed to concentrate or completely dry samples. The system will accommodate a wide selection of sample holders enabling evaporation from most common sample container formats including round-bottom flasks up to 500ml, tubes up to 160mm long, custom reaction blocks and shallow or deep-well microplates. To meet the need of the many life science companies switching their compound generation programmes from serial chemistry to parallel synthesis, the EZ-2 Elite is also able to take tubes, flasks and vials directly from the synthesis process, eliminating a manual handling step, increasing recoveries and removing the chance of cross contamination.
