Powder Systems launches laboratory filters Powder Systems Ltd has introduced a smaller version of its Glass Filter Dryer GFD® production filter dryer. The company says that this will allow easy laboratory scale filtration and drying with the same reliability and benefits as full size agitated nutsche filter dryers. This small scale filter dryer is suitable for all laboratory needs and is available in three filtration area sizes: MINI LAB (0.002m2 - 0.5L), LAB (0.01m2 - 2L) and MAXI LAB (0.05m2 - 10L). Its technology supersedes Buchner filtration, providing ergonomic and efficient drying. The GFD works in a vacuum and has a heated jacket for drying. To achieve a quicker
drying time while maintaining a homogeneous product, the GFD has an adjustable agitator running both clockwise and anti-clockwise for smoothing the cake. The PSL removable filtration basket allows total product collection, without having to dig the cake out of the vessel. PSL, a leader of glass filter dryer technology, launched the GFD two years ago. The new generation of Glass Filter Dryers benefit from new design features including a control/drive with RPM reading, O-ring groove in the glass body to ease fitting of the basket and a mechanical agitator height adjustment system. The latter allows easy adjustment of the agitator height in the slurry or cake in an accurate and repeatable manner.
The GFD also offers Laboratory FilterBox Technology. The FilterBox is a new technology consisting of a GFD being completely integrated within a PSL isolator, providing a high level of containment when handling highly potent APIs and other highly active or cytotoxic compounds. The FilterBox achieves containment to nanogram levels, protecting both the product and the operator during operations including charging, sampling, filtration, drying and discharging. The GFD FilterBox is an acrylic glovebox surrounding PSL’s MINI LAB or LAB Glass Filter Dryer. Larger options include the MAXI LAB GFD which can be incorporated within a full scale isolator in stainless steel for Kilo Lab or pilot plant applications. www.powdersystems.com
New nanofibre production concept is launched Xanofi, a nanotechnology company specialising in nanofibre applications, has introduced a new platform for nanofibre production – the XanoShear™
XanoShear can integrate nanofibres not just on the surface of substrates but also throughout the loft of the material.
machine. The company says that the first production unit is now fully operational and currently being optimised for high yield production. According to Xanofi, the machine is a unique high yield, liquid-based platform for nanofibre production – a radical departure from the previous production methods of meltblowing and electrospinning. The key to XanoShear™ is liquid. While other technologies produce dry, continuous fibres, XanoShear™ produces staple fibres that can disperse in water and integrate into existing production environments. The company has successfully produced products via wet lay manufacturing and is developing both wet and dry spraying capabilities. Several applications in filtration have
already successfully incorporated nanofibres using XanoShear. Xanofi adds that the XanoShear platform also has many other advantages – high scalability, ability to functionalise fibres at full production speeds with particles or coatings, and a closed system that uses less energy without the discharge of any materials into the environment for ‘green’ manufacturing. Miles Wright, chief executive officer of Xanofi added: “Until today, the nanofibre industry only had two platforms for nanofibre production, meltblowing and electrospinning. Today the world has an exciting new choice - XanoShear - that opens up new applications for nanofibres and achieves new financial metrics for products. www.xanofi.com
Laboratory Glass Filter Dryer from Powder Systems Limited
Automotive filter test laboratory to open in India Indian company FEC Group is opening a new Automobile Filter Test Laboratory in Delhi from 1 January 2013. The laboratory will test a complete range of automobile filters, such as air, oil, fuel and hydraulic filters, as well as filter allied product testing such as rubber parts, filtration media, adhesives and sheet metal components. Tests will comply to national and international standard test methods such as ISO: 4548-1,2,3,4,5,6,7,8,9.10,11 and12, JIS; ASTM; SAE HS06; and SASO. The company says that it has engineers with significant experience and expertise in the field of filter testing. www.fecproduct.com
