The perfect platform for live demonstrations, dialogue and new contacts POWTECH is more than just an exhibition. It’s where exhibits are tested live and specific solutions are developed with keen interest. Direct exchanges between experts mean that discussions are held on a level playing field and challenges are addressed directly from the ground up. This results in genuinely valuable and sustainable new contacts and business relationships. POWTECH is also the perfect stage for the next generation: As well as the key players, innovative young start-ups also present their new processes and product developments for the successful future of the industry. 4. Inspiration for tomorrow’s processing technologies Do you find that meetings, deadlines and cost pressures leave you with no scope for creativity during your daily work routine? The POWTECH 2023 supporting programme opens new perspectives. Be inspired by new impulses in our Expert Forum, special shows and pavilions, including topics such as explosion protection, food life science technologies, mandatory serialisation, and cleanroom technology. 5. POWTECH – the industry barometer 477 exhibitors from 29 countries and 7,688 trade visitors at the restart of POWTECH in 2022 underscore its importance for nearly all segments of industry, but especially chemicals, pharmaceuticals, metals and food. The process engineering supply chain continues to be a robust growth market. In 2023, POWTECH will reflect the fact that in many sectors, powder and bulk solids processing is being combined with fluid and liquid technologies to form an integrated process, and therefore the event specifically incorporates the processing and handling of liquids in its product range. Moreover, the important industrial sectors of cosmetics and batteries are being included in the exhibition for the first time. So don’t miss out. Make sure you are also part of the 2023 event with its new topics and technologies.

Tips and tricks for dispersing statically charged or hydrophobic sample material for particle measurement, in order to ensure an optimal analysis. The computer is only as smart as its user. We all know this saying and it applies at least as much to high precision, fully automatic analytical instruments, such as the FRITSCH Particle Sizer ANALYSETTE 22 NeXT. Even though much is already done automatically here, it is important for the user to know a few tricks and tips, especially with samples that are difficult to disperse, in order to ensure an optimal analysis. Particle measurement of easy-to-disperse samples Many samples require special preparation for measurement due to their material properties. If dispersion is necessary to be able to measure the primary particles, wet dispersion is the ideal form for most samples. Preliminary tests must be carried out to check in which way the sample material can be wetted and dispersed. The liquid should wet the solid as spontaneously and completely as possible. In wet dispersion, the sample material is placed in a closed liquid circuit and continuously pumped through

For monitoring of thermal effects, physical and chemical reactions and much more directly in the grinding bowl With the new EASY GTM Gas Pressure and Temperature Measuring System you can turn the Planetary Mills PULVERISETTE 5 and PULVERISETTE 6 of the FRITSCH classic line into analytical measurement systems. Due to the continuous measurement of gas pressure and temperature, thermal effects as well as physical and chemical reactions or pressure variations can be monitored directly in the grinding bowl. For this, simply insert the grinding bowl with the radio transmitter integrated in the lid, without any modification to the mill itself. The monitored data is transmitted to a computer via a receiver. The EASY GTMControl software included in the scope of delivery generates a graphical presentation of the measured values, which can also be offered as a PDF report and transferred to an Excel™ table. The EASY GTM-System provides valuable information - Investigations in the area of mechanical alloying for the production of new amorphous and nano-crystalline materials -
