Sample Preparation & Processing
Sample Concentration Prior to Analysis
Genevac Rocket Synergy, HT and EZ-2 series evaporators are designed to be very useful tools for lab scientists wishing to concentrate a sample safely and quickly. Genevac has remained an industry leader by partnering with customers to understand the obstacles involved in using centrifugal evaporation/ concentration systems. This partnership has led to the development of a range of innovations including Dri-Pure®, SampleGenie™, temperature control and highly solvent resistant build quality making Genevac evaporators the leading tools of choice for this concentration of samples prior to analysis.
Traditionally protocols for concentration of chromatographic fractions prior to analysis has involved drying multiple fractions in an evaporator, re-suspending pooled fractions into a single vial and then re-drying before storage and analysis. Even with modern centrifugal evaporators this process typically takes 2-3 days to complete. Now fractions can be pooled into a SampleGenie flask and dried directly into a submission vial in one evaporation run. SampleGenie is proven to reduce processing and evaporation times by up to 66% as well as eliminating the attendant risk of sample handling errors.
SampleGuard and SampleShield temperature control are sample protection features included in all Genevac Rocket Synergy, HT and EZ-2 series evaporators. These proprietary technologies monitor and control the maximum temperature of the samples to protect them from any possibility of overheating when evaporation is complete. In addition, Genevac’s patented Dri-Pure® sample protection system prevents cross-contamination and sample loss due to bumping and is fitted as standard on Rocket Synergy, HT and EZ-2 series evaporators.

New Generation High-Torque and High-Speed Stirrers Introduced
Wiggens introduces the new generation of high-torque and high-speed overhead stirrers with the WB-3000, WB-1800, and WB-6000 series. These units are specifically designed for high torque applications and/or high speed applications where conventional stirrers reach their limit with regard to sample viscosity or speed requirements.
The Wiggens high-torque and high-speed stirrers feature a high resolution TFT display which can show not only the current speed and torque, but also the set speed, gear stage, controlling mode and timer settings. All stirrers come with a BLDC motor, which is highly beneficial to the durability of the product. In comparison to AC motors, BLDC motors are more quiet, robust and maintenance free. In addition, all stirrers employ a two stage gear transmission box for optimal processing of high torque at low speeds or lower torque at higher speeds. A special feature is the smart torque adjustment that enables the stirrer to maintain the set speed even if the viscosity of the sample changes during the stirring process. The latest chuck design makes impeller changes easy and guarantees that the impeller sits perfectly.
The housing is made of die-cast aluminium and features heat reduction fins, which contribute to keeping the unit cool in long-term applications. An RS-232 and RS-485 input as well as analogue control make all stirrers highly versatile and adoptable for different applications. Thus, they can be used as a stand-alone unit or, for instance, integrated in chemical reaction systems.
The Wiggens high-torque and high-speed series are also available as remotely controllable units, with the stirring and controlling box separated. This makes them an even better fit for integration in reaction systems where the controller is required to be in an easily reachable position.

New Ball Mill for High Energy Milling Announced
With the new Emax Retsch has developed an entirely new type of ball mill for high energy milling. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time. The high energy input is a result of an unrivalled speed of 2000 min-1 and the innovative jar design. Thanks to the revolutionary water cooling system, the high energy input is effectively used for the grinding process without overheating the sample. Due to the special grinding jar geometry, the sample is thoroughly mixed which results in a narrow particle size distribution.
Unlike other high energy ball mills, the Emax is capable of continuous grinding operation without interruptions for cooling down. This dramatically reduces the grinding time. The high energy input in combination with the unique cooling system provides perfect conditions for effective mechanical alloying or grinding down to the nanometer range.
A wealth of safety features such as the integrated safety closure of the grinding jar, temperature control with automatic start/stop system, and integrated imbalance controls make operation of the bench-top mill Emax very user-friendly.
