Product News: Malvern showcases rheology and particle characterisation systems at K2007

30 Jul 2007

Visitors to the Malvern Instruments stand at K2007 (24-31 October 2007, Düsseldorf, Germany) will have the opportunity to learn more about the latest plastics industry applications for the company’s extensive range of rheometers and particle characterisation systems.

With outstanding digital drive systems, Malvern’s advanced capillary rheometers, including the Rosand RH10 and the benchtop RH2000, deliver high-level performance for plastics and other material applications. They will be exhibited alongside Malvern’s Gemini HR nano rotational rheometer, a valuable tool for exploring viscoelasticity. Laser diffraction and image analysis systems for particle size and shape measurement complete the line up.

The viscoelastic properties of polymers reveal important information about molecular architecture, processing behaviour and end product performance. Capillary rheometry is particularly relevant for polymer processors, allowing investigation of commonly encountered processing phenomena such as melt fracture, die swell and sharkskin.

The RH10 is a powerful floor-standing capillary rheometer used in research laboratories throughout the world; the RH2000 is a bench scale instrument ideally suited to routine QC analysis. Both have exceptional accuracy and speed control, and a very wide dynamic operating range. They are supplied with the latest Flowmaster™ software, offering a range of new experimental options.

Malvern's extensive knowledge and experience of laser diffraction is encapsulated in the Mastersizer 2000, an automated instrument used worldwide for particle size measurement. Easy-to-use, with exceptional reproducibility the Mastersizer 2000 is frequently the preferred option for the measurement of wet and dry samples in the size range from 0.02 – 2000 microns.

For applications additionally requiring shape information image analysis is appropriate. Morphologi is an automated image analysis system for the measurement of particle size and shape. Ideal for applications based on classification, such as the detection of foreign material, the images captured additionally provide information about optical density, homogeneity and particle structure.
