The modular concept of the MicroTec Plus consists of a central measuring unit with different dispersion units.
The dispersion units can be exchanged quickly and simply without tools: – Standard liquid dispersing unit: for dispersion of samples in water or most solvents – Dry dispersing unit: for dispersion of powders in an air jet – Falling chute: for dry, free-flowing coarse powders – Small volume liquid dispersing unit: to minimize waste when organic solvents must be used
An auto sampler, capacity 26 samples, can be used in combination with the standard liquid dispersing unit.
Particle Size range 0.08 µm (80 nm) to 2000 µm (2mm).
The patented measuring principle with convergent laser beam used by FRITSCH, offers a unique high resolution of up to 108 measuring channels (Particle Size Classes).
Dual laser technology with automatic alignment and user-friendly software.
The Laser Particle Sizer Analysette 22 MicroTec Plus, is a universal instrument for the determination of the particle size distribution of samples in powder form, of solids in suspensions, and of emulsions.
Applications: The instrument is suitable for quality and process control, research and development.

The large measuring range is possible using two lasers with different wavelengths. A semiconductor laser with green light is used to measure small to fine particles, and an infrared laser measures larger particle size ranges.
The FRITSCH measuring cell has the unique capacity to auto-align laterally, which translates to optimum alignment of the two laser beams, therefore the two measuring ranges can be adapted to the specific sample requirements.
The distance to position the measuring cell from the detector is determined by the particle size of the sample. For larger particles that have a narrow angle of diffraction, the detector is positioned further back, whereas for smaller particles that have a very wide angle of diffraction, the detector has to be closer. This technology offers a very high resolution with excellent precision.
The modular concept of the measuring units makes it easy to change from wet to dry dispersion or to small volume liquid dispersion unit, according to the sample, simply by exchanging the unit. Having separate modules also makes it easier to clean the units.
