Personal Solvent Evaporator Offers Optimised Stored Methods...
20 Oct 2009Product News
Genevac's long experience in vacuum engineering has resulted in the creation of a compact sample concentrator combining great performance, ease of use and compatibility with all commonly used solvents and acids.
Capability to input up to 10 stored methods now allows users to benefit from Genevac's wealth of experience in developing optimised protocols for a wealth of applications including environmental test methods, removal of very low boiling point solvents and degassing of aqueous ammonia or hydrochloric acid solutions.
To enable all users to achieve excellent results every time, the new compact EZ-2 has been made easier to use than a conventional rotary evaporator. In addition to accommodating many more sample formats (round-bottom flasks, tubes, vials, custom reaction blocks and shallow or deep-well microplates), it can operate entirely unattended. Simply set the temperature, select the solvent type, and press Start.
The EZ-2 is fitted with an enhanced version of Genevac's revolutionary SpeedTrap. This highly chemically resistant cold trap is designed to condense solvents, in order to protect the environment, and help to speed evaporation. The SpeedTrap runs at -50ºC to enable it to catch the most volatile solvents. However, it does not freeze the condensed solvent, even when working with water. Solvents collect in the insulated, plastic coated glass vessel, enabling the user to check the progress of evaporation and determine when the trap should be emptied. The glass vessel is removed by a quarter turn, allowing the solvent to be poured directly into the waste container. Replace the vessel with a quarter turn, and the EZ-2 is ready to run again. Incorporating state-of-the-art evaporation technology the EZ-2 is able to remove solvents in typically half the time of traditional evaporator designs.
Requiring no peripherals for operation the compact EZ-2 fits neatly onto a laboratory bench or into a fume hood. All key components on the robust and reliable system are user serviceable ensuring low cost of ownership.

EZ-2 Series
GenevacUsing the most advanced proven technology in evaporation science, the third generation of the EZ-2 Series has been designed specifically for solvent removal in life science research; be that concentration of samples or complete drying. The innovative design of the EZ-2 Series presents many advantages for working in parallel within synthesis chemistry, analytical sample preparation and for general-purpose solvent removal needs in life science laboratories. At the heart of the evaporator is a solvent resistant, oil-free vacuum pump, and the high efficiency, defrost-free, SpeedTrap™, which traps all solvents as liquids, even water. Solvents collect in the insulated, plastic coated glass vessel, enabling the user to see the progress of evaporation and determine when the trap should be emptied. The EZ-2 Elite has a special auto-draining collection vessel fitted to the SpeedTrap, which uses the very powerful Scroll pump. The Elite can therefore evaporate the highest boiling solvents such as DMSO and perform the Genevac LyoSpeed fast lyophilisation method for HPLC fractions. There is a low-cost option available on the Standard, Plus and Elite that allows the routine use of hydrochloric acid and aggressive solvents. By building key elements in Hastelloy®, glass or PTFE, full protection against acid chlorides is achieved. New to the HCl Resistance option is the ability to evaporate concentrated nitric acid. This option must be specified when ordering, as it cannot be retrofitted. All EZ-2 models are resistant to routine use of high concentrations of TFA as standard. An additional option is available to allow safe operation for those wishing to use highly explosive solvents, such as pentane or diethyl ether - the inert gas purge system. This system can also be used to preserve oxygen or moisture sensitive samples under an inert gas blanket until the user returns to the evaporator. The EZ-2 Series can also accommodate a wide selection of sample holders, including round-bottom flasks up to 500ml, tubes up to 160mm long (including Dionex ASE® and Radleys Carousel tubes), custom reaction blocks, and shallow or deep-well microtitre plates. EZ-2 Series Models: The Standard (EZ-2) is suitable for water and volatile solvents The Envi (EZ-2 Envi) is recommended for concentration of volatile solvents The Plus (EZ-2 Plus) is recommended for solvents with boiling points upto 165°C The Elite (EZ-2 Elite) is recommended for solvents with boiling points upto 220°C
