e200 LS

The NEXOPART e200 LS Air Jet Sieve Machine is an advanced laboratory solution for the separation, fractionation, and particle size analysis of fine and very fine powders.

Air Jet Sieving technology is particularly effective for materials that tend to agglomerate or clog conventional test sieves. By combining controlled airflow with the integrated eControl software, the e200 LS delivers fast, precise, and reproducible results while simplifying everyday laboratory workflows.

With a sample capacity of approximately 30 g and a sieving range from 10 µm to 4 mm, depending on sieve diameter and configuration, the system meets the demanding requirements of research, development, and quality control laboratories.

Operating Principle – Air Jet Sieving

The e200 LS operates using a rotating slotted nozzle positioned beneath the test sieve, combined with an external vacuum system.

The generated negative pressure draws air through the sieve mesh, dispersing particles and helping to break up agglomerates. Particles smaller than the mesh openings pass through the sieve, enabling efficient determination of particle size distribution.

This process ensures effective particle separation, excellent reproducibility, and reduced mechanical stress compared with conventional vibratory sieving.
