Miniaturized Pinch Valve

12.12.2012
<strong>Background</strong><br>

Pinch valves are operated by squeezing a flexible tube in a part of the valve by either moving a separate squeezing device against the tube or by impinging the squeezing part with an actuator. However, with current state of the art valves it is necessary to manually insert the tube between the squeezing device and the counter bearing which is in most cases rather complicated. Besides this, most of the pinch valves are as well pretty large and cannot be used in miniaturized or highly integrated systems. Thus the secure dosing of liquids that contain cells or other solids is with the currently available valves only possible when using exchangeable pinch valves.<br><br> <strong>Technology</strong><br> HScientist at the Technische Universität Berlin have now developed a pinch valve that overcomes the current disadvantages of the state of the art as it can be integrated into existing dosing systems as inexpensive single use valve.<br><br> It allows dosing very little amounts of liquid in a very fast, precise and highly dynamic way. As the valve is modularly constructed it allows an inexpensive mass production via injection molding, is easily adaptable to various applications and can be automatized mounted. Moreover it is uncomplicated to incorporate the valve into existing dosing systems without great effort. <br><br> For further information please see also the following link: http://www.process.vogel.de/index.cfm?pid=7085&pk=336319&print= (article in German)

<br><br> <b>Benefits:</b><br> <ul> <li>Injection/ejection also possible under counter pressure</li> <li>Usage of different tube diameters in one valve -> realization as mixing valve possible</li> <li>Valves can directly be flange-mounted or molded </li> <li>Allows fast switching cycles by keeping a very high precision</li> <li>Especially for dosing cell- or solid-containing liquids as there are no cleaning or contamination problems </li> </ul><br> <strong>IP Rights</strong><br> EP and US application with priority on June 2010 <br> <br> <strong>Origin</strong><br> Technische Universität Berlin

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
