NO ONE UNDERSTANDS PARTICLE SIZING BETTER THAN MALVERN. MasterSizer is the result of over 12 years' experience in laser diffraction particle sizing at Malvern. Its wide size range, 0.1 to 600 microns, and fully automatic sample handling facilities make it ideal for on-line or laboratory applications. The Small Volume Sample Presentation Unit is a particularly useful accessory for organic media as well as for aqueous samples.
Automatic alignment and Malvern's acclaimed software make MasterSizer easy to use. And yet, whether you select the standard analysis or choose to enter the specific optical data for your sample, you get full Mie theory analysis - vital where small particles are concerned. Data/results storage on disk and a wide range of report formats are standard. Colour display, colour plotter and 32-bit processor are among the options.
