Fritsch GmbH’s Milling and Sizing division, Idar-Oberstein, Germany, has expanded the particle size range of its ANALYSETTE 22 NeXT to include Micro (.005-1500 µm) and Nano (.001-3800 µm) sizers.
The latest generation of ANALYSETTE 22 NeXT operates like the other sizers in this series, without any additional light source required due to the use of a single laser. This means that the sizers can record an entire measuring range in a single scan, which can be completed in under a minute using wet dispersion.
The dispersion unit of the sizer is designed for long, low-maintenance service life. Without valves and moveable seals in the sample circulation system, no space is left empty, which means no sample material can accumulate and settle. A centrifugal pump with individually adjustable speed is expected to ensure stable measuring in the dispersion unit; to measure samples tending to agglomerate, a user can add an ultrasonic box to the sample circuit.
Those interested in these products can send a sample measurement to the company for analysis protocol. Further information is available via the company website.
