Powder Rheometer Optimises Metal Powders for Additive Manufacture from Freeman Technology to research new powders and exert control over product performance.
LPW Technology, a leading supplier of optimised metal powders for high end additive manufacturing (AM) applications, is using the FT4 Powder Rheometer®
“Powder testing is a critical part of what we do, both in the development of new powders and as a service for customers looking to optimise existing AM processes,” explained Dr Robert Deffley, Research and Development Manager at LPW Technology. “We’ve long used traditional testing techniques such as angle of repose, but these have inherent limitations. We have seen examples of two powder batches which meet the same specification showing very different behaviour, which made it necessary to look for a new method of characterisation with greater sensitivity. We considered shear cell testers, which are good for silo and hopper specification, but this test alone couldn’t accurately measure powder properties under the conditions needed to provide relevant data for additive manufacture. With the FT4 we still have shear cell capability, if we need it, but also bulk property measurement and, most importantly, dynamic characterisation capability.”
“AM is advancing fast and this creates new demands for the powders used,” said Dr Deffley. “AM processes are currently used to produce components with ‘fit and form’, that is prototypes used for advanced product development. The next goal is to robustly engineer in ‘function’ – the controlled porosity for a replacement bone, for example, or complex channels for a more efficient aerospace cooling system. We’re learning that to rigorously cater for these applications we need a more robust understanding of our powders and that these must have tightly controlled, repeatable behaviour which is consistent from one batch to the next.”
The dynamic powder characterisation capability of the FT4 Powder Rheometer is based on measurement of the powder in motion and directly quantifies how the powder flows. Powders can be tested in a consolidated, conditioned, aerated or even fluidised state to fully understand the response to the process conditions. Complementary bulk and shear property measurements add to dynamic data to fully characterise the powder.

Advanced Chemistry Functionality Added to E-WorkBook 9.4
A Turnkey Solution for Forensic Identification
Genia Geo, based in Montevideo, Uruguay, has chosen Tecan’s HID EVOlution™ system as part of its comprehensive forensic identification services for governments around the world. This one-stop solution encompasses everything from designing and building laboratories to training crime scene investigators and judges, and revolves around Tecan and Life Technologies’ fully validated, walkaway set–up for robust genetic identification. Dr Carlos Azambuja, President of Genia Geo, explained: “Genia Geo was set up to provide government entities, such as Ministries of the Interior or of Justice, with everything necessary to implement a national system for DNA- based forensic identification. Although we did not have previous experience with Tecan equipment, the HID EVOlution represented a fully integrated processing system that could help to simplify laboratory workflows and improve process security. We were able to visit several other laboratories using the HID EVOlution set-up, and they were very positive about both the equipment and the Tecan service, so we felt very comfortable with our choice.”
“We are still in the early phases of the project, so are not really using these systems to their full potential yet, but so far the instruments have been very easy to use. The software is user-friendly, and we have received very good support from the Tecan team to help integrate the systems into our complete laboratory workflow. We are now looking to provide the same comprehensive service in several other countries, and Tecan will certainly be at the forefront of our minds for these projects,” Carlos concluded.
IDBS has added advanced Chemistry functionality to E-WorkBook 9.4 including key data visualisation and data analysis capabilities. The new release includes chemical drawing and representation for organometallic structures. Users can now capture a wider variety of molecular types and streamline chemistry data input. Chemists are given access to vital experimental information to progress research. It also provides a customisable chemical data lookup functionality which speeds up collaboration and data retrieval from external repositories.
IDBS’ latest version supports direct addition of data to experiments at point-of-use to help save valuable time and avoid duplicating work. Removing the need to copy and paste information across data libraries safeguards accuracy by reducing potential for error. Improved reaction stoichiometry workflows also offer increased data analysis capabilities in fewer clicks.
“Chemists need a platform which helps manage significant volumes of experimental data and enables them to access and strategically use all available information. This advances research and development (R&D) and chemists can make decisions faster, without being slowed down by paper and technology limitations,” said Scott Weiss, Director of Product Strategy at IDBS. “These enhancements reflect E-WorkBook 9.4 Suite’s flexibility to meet specific domain needs as well as moving beyond the typical ELN paper replacement tool.”
E-WorkBook 9.4 also delivers enriched PDF lifecycle and task flow capabilities which enable users to generate PDF content online and sign work digitally. The optimised task flow functionalities ensure efficient reporting and, importantly, IP protection, applicable across all domains. These features deliver a functionality rich browser-based solution in combination with the 9.4 enhanced web client.
IDBS’ E-WorkBook Suite is a single platform solution with a range of flexible applications for data and sample management, analysis, reporting and IP retention. Suitable for small or large organisations, it can be deployed quickly, is easy to use and has a proven track record of robust performance.

27785pr@reply-direct.com Chiller Now Reduced in Price
Huber has significantly lowered the price of its RotaCool chiller, the best solution for cooling rotary evaporators on the market. The RotaCool is now available for only €3.780 - a reduction in price of almost 20%.
The RotaCool is the only chiller designed especially for rotary evaporators. The space saving concept of the device due to its ‘L’ shape design is unique. The evaporator is placed directly on the RotaCool; no additional space on the laboratory table is required.
The RotaCool provides space of (WxD) 470 x 405mm. Cooling capacity and circulation rate are tailored to the requirements of conventional rotary evaporators.
Features include:footprint of chiller WxDxH: 470x580*x420 mm (*582 mm with removable extension plate); temperature range from -10°C to +40°C; display for setting temperature and reading out actual temperature.
The new list price is immediately effective for new orders.
