Industry news

Solvent removal is an essential process for sample preparation across a wide range of applications in many industries. Many sample formats and solvents are used with no single technique providing a universal solution, but despite this evaporation technology is well-understood and relatively uncomplicated.

But while evaporation is an intrinsic step in so many applications it’s rare to find an evaporation expert in a laboratory. Consequently, many facilities use systems that are slow and cumbersome simply because of a lack of knowledge about evaporation technology and techniques.

‘Introduction to Evaporation’ has been written to provide practical informed advice on how solvent evaporation and concentration can be made simple, safe, efficient and effective. This guide provides a basic grounding in the science, looks at the most effective evaporation technologies for specific applications, offers tips to avoid common evaporation mistakes, and takes a look at the latest developments in evaporation technology.

Sample Genie
Genevac
SampleGenie technology, in conjunction with Genevac Rocket Synergy, HT and EZ-2 series evaporators, enables large sample volumes to be dried directly into vials, eliminating a number of time-consuming sample handling steps and the attendant risk of errors. Traditionally protocols for concentration of chromatographic fractions has involved drying multiple fractions in an evaporator, re-suspending and pooling fractions into a single vial and then re-drying before storage and analysis. Even with modern centrifugal evaporators such processes typically take 2-3 days to complete. Using SampleGenie pooled fractions can be dried directly into the final submission vial, reducing the process time by up to 66%. Available for starting volumes of up to 60ml, 125ml and 250ml, SampleGenie is compatible with a wide range of HPLC, GC and storage vial sizes.

Rocket 4D Synergy Large Volume Evaporator
Genevac
Rocket 4D Synergy is designed primarily to evaporate large sample volumes, with autofeed if required, allowing automatic evaporation of volumes up to 100 litres. Rocket 4D Synergy provides fast, safe evaporation for solvents with a boiling point of up to 165°C (DMF) and can easily dry aqueous samples. The system feeds the solution for evaporation to the evaporation vessel, controls temperature and pressure, prevents bumping and foaming, drains the condenser, stops when dry or concentrated, and if required, redissolves the product in a small volume of solvent, unattended, and with no user intervention. The Rocket 4D Synergy can also be fitted with a removable flask rotor to accommodate the full range of Rocket Sample handling solutions such as flasks, tubes and SampleGenie. Now you don't need to choose between flask or batch/feed evaporation. The Rocket and Rocket 4D Synergy evaporators will accommodate your process, whatever the volume. Each is capable of replacing several rotary evaporators and saving valuable bench space.

EZ-2 Series
Genevac
Using 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
