Atlas Releases New Fluorescent Weathering Device, UVTest
USA-based Atlas, a supplier of material testing equipment, is excited to announce a new fluorescent UV testing device for accelerated weathering. Atlas has 90 years of experience in the development of weathering testing equipment. The objective of artificial weathering is to reproduce real life product failures in a laboratory under accelerated and reproducible conditions. Fluorescent UV lamps are one light source used to simulate specific solar spectral power distributions. These sources are incorporated into fluorescent UV condensation devices like the new UVTest. According to Atlas, the UVTest is a low cost economical artificial weathering device which has a number of easy to use features, including simple touch-screen operations and controls, pre- programmed and custom tests for error free operation, and advanced calibration technology. Atlas’s engineering manager and UVTest project leader, Rich Schultz,
commented: “Our
engineering and design teams spent a considerable amount of time and effort
reviewing the current state-of-the-art technology for fluorescent UV devices. Based on customer feedback and insight from industry experts, we were able to improve upon almost every aspect of the design and functionality without departing from established test environment geometry and performance, which is critical to the integrity of our customers’ ongoing test programmes.”

Simulation Software and Rheometers Accelerate Testing
For polymer processors seeking to cut development time and cost, the combination of advanced simulation software from Czech Republic-based Compuplast and powerful capillary rheometers from UK-based Malvern Instruments offers a compelling solution. Malvern’s Rosand bench-top and floor- standing rheometers measure the flow properties of polymers with precision, providing a sound basis for the construction of representative process models. Compuplast software makes it easy to use the data to simulate extrusion and other polymer processing operations—which reduces the requirement for expensive and time- consuming pilot scale trials. According to John Perdikoulias, vice president of Compuplast: “Evaluating different operating regimes with a process model is quicker and less expensive than with an equivalent laboratory or pilot programme. But the quality of the simulation is key. Malvern rheometers can provide the material data that Compuplast software requires to develop a simulation which accurately reflects process behaviour. Simulating alternative operating strategies, equipment designs or materials identifies
an optimal operating condition.” Malvern’s Rosand range of capillary rheometers includes the RH2000 bench-top series and the RH-7 and 10 advanced floor- standing units for higher loading studies. A new digital drive gives all these instruments good performance in terms of speed control, accuracy and dynamic operating range. Combined with twin bore configurations, these features allow the simultaneous determination of shear and extensional viscosity under processing conditions. The rheometer hardware is supported by the latest Windows-based Flowmaster software, offering an extended range of rheological test types and experimental possibilities.

New Spectrophotometer Allows Online Calibration
The new Lovibond PFXi spectrophotometer from UK-based supplier of colour management systems Tintometer provides a unique concept in liquid colour measurement. For the first time, this type of equipment offers the capability for remote calibration and servicing via the internet—eliminating costs and time delays associated with servicing. The spectrocolorimeters in the system are simple to use with no need to build up calibration curves, as these are already established in the instruments. A large and clear LCD (liquid crystal display) screen allows graphs and data to be viewed in a wide variety of languages while an easy to use menu system guides operators through the selection of operating parameters. Measurements are initiated by just a single key stroke. Instruments provide accurate, repeatable and reproducible data, which allows for tighter colour specifications and greater colour consistency, giving companies greater confidence when making decisions based on colour measurement.

The PFXi range is supplied with a full range of colour scales for specific markets including, but not limited to, petroleum, edible oils, pharmaceuticals, brewing and honey. A remote upgrade feature enables users to easily and flexibly add and upgrade colour scales once the instrument is in service. A comprehensive list of available scales and advice on the selection of scales can be obtained from Tintometer.
