John Morris Scientific -
John Morris scientific are pleased to introduce Fritsch’s High resolution Laser Particle Sizer, the Analysette 22.
The Laser Particle sizer has a unique optical measuring cell which allows greater sample resolution.
The Analysette 22 approaches particle sizing in a new way, the Laser Particle Sizer allows the user to set a narrow range encompassing the target particle size and then optically zooming in on just that area for a far greater non software interpolated result. The Laser Particle Sizer also allows full measurement range scanning where the end user is still exploring the physical properties of their end product.
There are four models in the Laser Particle Sizer range, Compact, NanoTec, MicroTec and MicroTec XT. The Compact is the standard model with a measuring range from 0.3 to 300 µm. The Compact is idea for users in need of a bench top instrument for routine particle size analysis which is simple to operate either in a laboratory or in production.
The NanoTec is the top model in the Fritsch Laser Particle Sizer range. Taking into consideration backward scattering, the lower measurement limit is 0.01 µm. The total measurement range from
0.01 – 1000 µm can be switched to 15 – 2000 µm through beam expansion. The Zoom function resolves the particle distribution of a sample in up to 520 measurement channels.
The MicroTec is different to the NanoTec by its smaller measuring range. Because the backward scattering is not captured, the lower measurement limit is 0.1 µm. The upper measurement limit of 600 µm permits the use of a shorter optical bench, resulting in a compact design. The MicroTec XT has a larger upper measuring range than the previous model of 2000 µm
For particle characterisation, both the size distribution and shape parameter can be identified. The Analysette 22 is the only instrument with which you can obtain a particle size distribution and particle shape analysis in a single measurement.
