A cleaning product manufacturer recently purchased a Flashmix after it improved their existing process time by over 23 hours. The company wanted to eliminate


agglomerates from their powder/liquid mixes and try to reduce their process times. They also wanted a mixer that could handle a number of different powders for their different products, such as Xanthan gum, CMC powder, Carbomers and pigments.


Previously, the company had been using a high speed agitator to disperse Xanthan gum into vinegar. This process had been taking 24 hours or more and additional time was then taken to filter out agglomerates which had formed in the mixture as the impeller was unable to get rid of them Not only were they wasting money on long processing times, high energy requirements and raw materials, even after 24 hours the quality of the mix was poor and there was no consistency between batches.

feiffer Vacuum has received yet another major order for leak detectors from CERN. CERN is seated in Geneva on the


Franco-Swiss border and is the largest center for particle physics research in the world. Its main business is fundamental physics – finding out what the universe is made of and researching the basic constituents of matter. The particle accelerator LHC (Large Hadron Collider) has a circumference of some 27 kilometers and collides proton or ion beams at nearly the speed of light. The LHC is the largest vacuum installation on Earth with thousands of welds, flanges, feedthroughs and complex internal circuits. For the accelerated particles to travel in beam lines, ultra-high vacuum (UHV) is essential. To maintain such a very low pressure it is crucial rates as low as possible. The most advanced leak


detector technology to keep the leak


from Pfeiffer Vacuum has been chosen by CERN. Andreas Schopphoff, Head of R&D Market Segment: “The cooperation between CERN and Pfeiffer Vacuum is based on many years of working together in a spirit of trust. We are very proud that our advanced leak detection technology has been chosen once again for its future projects.”


The leak detector ASM 340 is an easy to operate device that can detect leaks down to < 5 x 10-13 Pa m3/s. With a built in backing pump of 15 m3/h small as well as big volumes can be leak tested. The patent pending functionality makes it possible to start at 100 hPa which can be very convenient for such a big installation like the LHC. Furthermore, the leak detector is so compact that it can be easily maneuvered underneath the cryostats and beam lines of the LHC. Nowadays helium leak detectors are based on a patented design from Dr. Becker at Pfeiffer Vacuum who proposed to use a turbopump as a kind of filter and safety element in front of a mass spectrometer. At the time, CERN was one of the first customers to buy this innovative technology and has continued to be a major user of Pfeiffer Vacuum products to this day. Generating the vacuum inside the LHC, measuring it and analyzing the partial pressure requires comprehensive vacuum technology, a major part of which is being supplied by Pfeiffer Vacuum. CERN was founded in 1954 and now employs around 2500 staff and hosts more than 10,000 visiting scientists from all over the world.
