49 Sample Preparation & Processing Fully Automated Sample Preparation System Accelerates Chromatography Workfl ows
The new Thermo Scientific EXTREVA ASE Accelerated Solvent Extractor is the first system to automatically extract and concentrate analytes of interest from solid and semi-solid samples, such as persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs) or pesticides, in a single instrument, eliminating manual sample transfer for a walk-away sample-to-vial workflow.
The system is also the first to perform four sample extractions and concentrations in parallel, significantly improving sample throughput and laboratory productivity. With manual intervention significantly reduced by a factor of three, in some cases, results can be more accurate and reliable - allowing users more time to focus on value-added tasks. Analytical labs extracting from solid or semi-solid matrices can pair the sample prep instrument with gas chromatography (GC), GC-mass spectrometry (MS) or liquid chromatography (LC)-MS systems.
“Traditional sample preparation for chromatography with solid or semi-solid samples is labour-intensive, prone to errors and can stifle lab productivity,” said Dino Alfano, Vice President and General Manager, Ion Chromatography and Sample Preparation, Thermo Fisher Scientific. “Even with current automation solutions, the process can involve time-consuming manual navigation of multiple instruments. By seamlessly performing sample extraction and evaporation of four samples in parallel, the EXTREVA ASE system redefines this cumbersome workflow. Streamlining workflows allows our customers to reduce manual sample preparation steps from hours to minutes, thereby increasing their productivity, minimising errors, and dramatically reducing solvent use; ultimately helping them meet sustainability and cost goals.”
Matthew MacLennan, director, LC/MS/MS DevOps, Pacific Rim Laboratories, said: “We are looking to innovate our processes with technologies that will enable us to extract the most difficult and complex matrices with ease. EXTREVA ASE does just that for our POPs extractions.”

IR Hotplate/Stirrer Delivers Superior Heating and Mixing
The latest infrared heating technology has been used in the design of the WH280-NH hotplate-stirrer from Wiggens. Thanks to this radiation heating technology, the Wiggens WH280-NH can be used for rapid heating up of various shaped vessels, including round-bottom flasks, and the solution inside can be heated up to a maximum of 450°C in a very short time.
The new Wiggens hotplate stirrer enjoys the benefits of a Schott glass ceramic surface with exceptional chemical resistance, a high surface quality, and a resistance to temperature shocks of more than 700°C, providing users with an optimal solution compared to conventional heating surface materials. The poreless smooth surface enables even the most stubborn dirt to be easily cleaned. The high infrared permeability ensures that the heating energy is transferred quickly and with very limited loss, therefore, it heats liquids fast and saves time and energy. Intelligent Cascade Control enables self-optimising to reach perfect temperature stability. If the Pt-100 sensor is connected, temperature-controlled work with stability of +/- 2°C can be reached in most applications.
In addition to rapid heating capability and superior temperature control, the WH280-NH also offers well controlled gentle to intense mixing of liquids, and is also suitable for large volume viscous media.
The stirring and heating can be controlled separately by convenient turning knobs. All functions can be viewed and monitored on a bright touch screen, including most frequently used parameters, such as, working temperature, stirring speed, working time, and safety temperature. Memory function for stirring speed and temperature setting makes it convenient to start the experiments with fixed conditions. A residual-heat display protects the users from burning their hands.
With the aforementioned benefits, and many other features, the Wiggens hotplate stirrer is the optimal solution for heating and mixing of liquids in labs, for gentle to intense applications.

Scalable Continuous Flow Photochemistry
The PhotoSyn™ high power LED photoreactor, from Uniqsis, eliminates problems associated with traditional batch methods enabling synthetic chemists to routinely scale-up their photochemistry reactions from milligrams to several kilograms / day.
The PhotoSyn™ is designed to provide scientists with a high-power LED light source for continuous flow applications. Using a pair of enclosed curved cooled LED arrays, the PhotoSyn™ efficiently focuses light inwards onto a central coil reactor. Each array is composed of 360 individual LEDs that provide a high photon intensity to facilitate reactions in coil reactors (up to 52 ml) and enabling easy reaction scale-up.
The unit is available with different standard LED configurations including 365nm and 455nm as well as a 3-colour option of green, white, and blue. Custom excitation wavelength versions of the PhotoSyn™ are also available on request. Offering the versatility to be optimised to suit your photochemical application, the PhotoSyn™ is designed to integrate with the Uniqsis Cold Coil™ and the Polar Bear Plus Flow™ reactor modules.
To maximise safety, PhotoSyn™ has been designed to operate without any light leakage, and therefore does not require a tinted or light-tight enclosure. Safety interlocks are also fitted to prevent the possibility of accidental exposure to high intensity LED light should an attempt be made to remove the PhotoSyn™ from the reactor module whilst in operation.
