35 Personal Solvent Evaporator Offers Optimised Stored Methods
Genevac Ltd has announced the launch of a new third-generation version of its popular EZ-2 personal solvent evaporator. Using advanced evaporation science, it has been designed specifically for productive, sample-safe solvent removal, be that concentration of samples, or complete drying.
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, 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.
Circle no. 405 ADVERTORIAL Multiply your Rotavapor®
Büchi Labortechnik AG, known as a market leader in rotary evaporation, breaks new ground in multiple sample processing.
The Multivapor™ P-6 / P-12 are compact instruments for the parallel evaporation of up to 12 samples simultaneously. It has been specially designed so that it can operate either as a stand-alone instrument, or in combination with an existing Rotavapor®
.
This synergistic and compact design saves space in the lab and is designed to fit into specific process workflows where the evaporation of multiple samples is considered a bottleneck. The Multivapor heats and agitates up to 12 samples in individual cylindrical transparent water bath. A flexible sealing system with a range of specific adapters allows the system to be used with a broad range of common glassware – including Carousel tubes, microwave vials, and PSE vials - rendering the time-consuming sample transfer steps obsolete. Bumping is prevented by inducting a vigorous vortex in the sample by means of the orbital agitation. Additional splash protection frits guarantee a fast and safe parallel evaporation without the risk of cross-contamination. This feature makes the Multivapor the ideal way to work up samples quickly, easily and safely!
In addition to the combination with a rotary evaporator, the Multivapor is also available as a stand-alone parallel evaporator with a vertical PLASTIC+GLASS coated condenser and the Büchi vacuum pump V-700. Equipped with the sophisticated vacuum controller V-855 parallel evaporation is a cinch. This technique is in accordance with the regulations of ISO 14000 which require most environmental health processes as possible.
