New Bohlin Gemini Hr Nano and Extended Range Accessory for Morphologi G2

Mar 13 2006 Read 2256 Times

The Bohlin Gemini HR nano is a new addition to the Malvern Instruments rheometers range and like all previous Bohlin High Resolution rheometers, it offers advanced technology with straightforward operation. Optimized for the control of ultra-low torques, the Bohlin Gemini HR nano opens up new opportunities to probe weak or sensitive material structures and low viscosity systems. While enabling the measurement and control of nano-torque levels, it retains a continuous working torque range to 200 mNm allowing complete rheological characterization.

Development of this rheometer has been made possible through the continued advancement of Malvern's state-of-the-art air bearing design coupled with its patented Rotonetic? 2 DSP drive system. The Bohlin Gemini HR nano's unsurpassed range and sensitivity allows torque and speed control across all steady, dynamic and transient test modes. Both strain controlled and stress controlled tests can be performed with ease.

The Morphologi G2 high sensitivity particle image analyzer will be shown, together with its newly extended measurement range accessory kit. Launched at the end of last year, the Morphologi G2 is based on digital image analysis and automated microscopy. It measures particle size using circle equivalent diameter, and employs a variety of parameters for particle shape analysis. This enables the determination and quantification of even small differences between particles.

The Morphologi G2's new extended range accessory kit comprises a low magnification objective and wide field of view condenser element. This widens the dynamic range considerably by extending the upper limit of measurement from 1000 to 3000 microns. This will expand the number and type of applications for the G2. Customers in the pharmaceutical industry studying the granulation process, and in the nuclear industry studying functional bead production, are already seeing the benefits.
