Genevac has introduced the EZ-2 Elite, designed to remove high-boiling-point solvents and deliver enhanced solvent recovery, to its EZ-2 evaporator range.
The EZ-2 Elite is said to improve the 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 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 Elite solvent collection vessel to allow mid-method defrosting and draining.
This controlled draining facility enables 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 on an EZ-2 evaporator for the first time.
According to Genevac, running the EZ-2 Elite is simple.
Users can load their samples, select the maximum safe temperature for the samples, select the solvent type and hit start.
Offering true unattended operation capability, the EZ-2 Elite requires no user training, the company added.
The EZ-2 Elite has been designed to concentrate or completely dry samples.
The system will accommodate a 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.
For 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.
