The versatile classic for automated particle size analyses for suspensions and emulsions from 0.1 µm to 1,750 µm
The laser diffraction sensor HELOS/KR covers a wide range of particle sizes with its long optical bench. In combination with the powerful SUCELL wet dispersion unit, this configuration offers reliable and true-to-method particle size analyses for finely to coarsely dispersed suspensions and emulsions from 0.1 µm to 1,750 µm. Equipped with a stainless steel basin with a nominal volume of 400 ml and a peristaltic pump, SUCELL is a proven solution for closed loop measurement tasks. For smaller sample volumes, a small volume adapter allows the analysis volume to be reduced to 50 ml.
The powerful sonication is capable of dispersing even highly agglomerated suspensions directly in the basin. Two immersible stirrers reliably homogenise the sample, and the pump ensures that there is a steady flow through the measurement cuvette. The cuvette type used with layer thicknesses of 2 mm or 4 mm is automatically detected. Rinsing, filling, degassing, addition of additives, pump and stirrer speeds, sonication and the trigger for the measurement can be controlled using the operating panel or the software and saved as retrievable measuring methods (Standard Operating Procedures (SOPs)).
Different materials are available for gaskets and tubes to ensure that the chemical resistance is matched to the dispersing liquid (Marprene®, silicone, FKM, EPDM or CHEM-SURE®).
The modular concept of the HELOS laser diffraction series allows this configuration to be systematically expanded with numerous dispersion units and dosing options to open up many more product-appropriate measuring applications. If frequent changes between dry and wet dispersion are required then the SUCELL is optionally available with the proven dry dispersion unit RODOS as a combined dry and wet dispersion unit OASIS. For applications with a higher product throughput, there is also an option to incorporate a liquid reprocessing system in the form of LIQIBACK in order to ensure a sustainable use of the dispersing liquid.
