Tessek Ltd. offers classification of hplc sorbents, solid particles and powders. Our pilot plant laboratory is equipped with a sophisticated system of ALPINE and ALGAIER classification apparatus operated by well skilled and well experienced staff. This enables us to classify not only sorbents for HPLC and GC but also many other powdered materials with particle size 3 - 250 µm supplied by our customers. We offer great accuracy, narrow particle size distribution curve and good yields at reasonable prices. For your basic information see enclosed ranges of typical classification carried out for HPLC sorbents.
The particle diameters are evaluated by means of microscopy in a dry state. When desired, materials with larger particles can be desintegrated before classification.
