24 High Speed Digital Homogeniser Introduced


Wiggens introduces a new generation of digital high speed homogeniser D-500D, which enable the best possible result whether used for homogenisation, emulsification or suspensions.


The high-performance dispersing instrument is used for volumes range from 0.05 to 2500 ml and come equipped with a large digital display. The electronic control system continuously monitors the speed and automatically adjusts it, keeping it constant with changing viscosity. The homogeniser offers a wide speed range up to 30,000 rpm that enables users to work at high circumferential speeds even with small aggregates diameters. The high efficiency and uniqueness of the aggregate can meet all kinds of applications in sample preparation, chemical, pharmaceutical, cosmetic, and food industry, as well as the life science branch.


Many different styles of aggregates are available, from 3mm in diameter for volumes down to 0.05 ml, and 25mm for volumes up to 2500ml. Advanced technology ensures the quick-connect coupling/removing and fast cleaning. Single use aggregates in 7 and 12 mm diameters are also available for the cross contamination unacceptable application.

The new Type 8766A lightweight, triaxial accelerometer from Kistler Instruments uses the, patented PiezoStar®


crystal developed by


Kistler to provide ultra-stable performance with very little sensitivity deviation with temperature changes. Over a temperature range of -50°C to +165°C a PiezoStar®


sensor has a sensitivity


deviation with temperature which is over thirty times better than a similar quartz sensor. The Temperature Coefficient of Sensitivity of a quartz triaxial accelerometer is 0.18 %/°C, compared with only 0.005 %/°C for a 250g measurement range for the new PiezoStar triaxial accelerometer.


24th - 26th January 2018, Cardiff, UK 15th International Symposium on


Hyphenated Techniques in Chromatography and Separation Technology


HTC 15 will take place in the historic city of Cardiff and will cover all fundamental aspects, instrumental developments and applications of hyphenated chromatography techniques. These include hyphenation between chromatography and new detection systems, multi column (multi-dimensional) chromatography, and the coupling between sample preparation and separation techniques. Many aspects of chromatography are addressed, including automation, miniaturisation, and micro fabricated analytical devices, high pressure and high temperature LC.


Besides the core scientifi c programme, the symposium will host an attractive technical exhibition where companies active in the fi eld will present their latest developments in instrumentation, software and applications related to the hyphenation of separation, detection and sample preparation techniques topped with technical seminars.


The new accelerometer has been designed specifically to bring these unique properties to applications demanding high accuracy measurements in varying temperature up to 165°C. The small cubical, hermetic titanium housing has threaded mounting holes on each of three sides to facilitate calibration and simplify installation for tests whilst the low mass of only 4g reduces any influence on the test structure. The Kistler PiezoStar® shear element design provides a flat frequency response over a wide operating frequency range and extremely low sensitivity to temperature changes.


The IEPE sensor combines the PiezoStar® crystal with high gain, integral, hybrid microelectronics to achieve very low sensitivity variation over the wide operating temperature range, compared to other sensing element designs, and high immunity to base strain errors. The Transducer Electronic Datasheet (TEDS), embedded in the chips integrated within the IEPE sensor, enable data acquisition systems to automatically recognise the sensor specification and so reduce set up time, minimise risk of human errors and eliminate the need for manual point-to-point connection identification.


Five variants cover the measurement range from ±50g to ±1,000g all with a 100% overload capability plus a high temperature option for temperatures of up to 165°C. In contrast to ceramic and quartz, the extremely stiff piezoelectric crystal sensing element offers a flat frequency response with no slope across the entire useable frequency range of 0.5 to 20,000 Hz.

The accelerometer uses a welded titanium construction for low mass and an industry standard 4 pin connector, as well as a mini 4 pin connector option for lower mass and wider frequency operation. A range of ground isolated mounting bases are available with adhesive, threaded and magnetic mounting options and an integral silicone cable variant is available for underwater vibration testing at up to 10 bars (150 psi).
