Crystalsizer particle size analyser

The Crystalsizer is a reliable, easy to use and robust instrument for the particle size analysis of a wide range of free-flowing and dry dispersible solids in the measuring range 0.7 to 2500 µm. Even optically difficult or sensitive materials can be measured using its measuring technique.

The Crystalsizer uses a measuring principle using incoherent diffraction analysis that unites the advantages of mechanical and optical measuring devices. This advanced technology allows the Crystalsizer to operate in difficult environmental conditions, to handle large samples and achieve precise reproducible results. Essential for achieving these advantages was the development of a high-resolution liquid crystal display which is the central core of the set-up and has provided the name for the device.

Very fine materials tend to agglomerate, which then makes it impossible to analyse them without dispersing them. To solve this problem the Crystalsizer is equipped with an optional compressed air dry disperser unit. It creates shear forces which break up the agglomerates into fine powder, just before it enters the optical path, and in that way an optimal analysis of the primary particles is made possible. Inconvenient wet dispersing, therefore, is not required. The Crystalsizer is a compact benchtop instrument, virtually maintenance-free with all optical components continually flushed by an air stream. Suited to industrial environments, the Crystalsizer is insensitive to dust and vibration and can be easily modified for online application.
