NEXOPART e200 LS Air Jet Test Sieve
A 203×28 mm stainless-steel test sieve for the NEXOPART e200 LS, available to DIN ISO 3310-1 or ASTM E11.
View component details →Product overview
The NEXOPART e200 LS is an air jet sieve machine for particle-size distribution and sieve analysis of powder samples, with sample weights up to approximately 30 g. It is operated through a touchscreen and integrated software and is available with four optional packages: Lite, Basic, Ultimate and Security.
Air jet sieving principle
A rotating slotted nozzle is positioned below the test sieve while an external suction unit creates negative pressure in the sieving chamber. The accelerated airflow passes upward through the sieve mesh, disperses and deagglomerates the powder, and carries fine particles through the apertures. This avoids the mechanical stress associated with vibration or tapping.

Package selection
- Lite: for basic one-touch sieving with manual negative-pressure control.
- Basic: adds automatic pressure control, central sieve parameters, RFID recognition and RS-232 balance communication.
- Ultimate: for laboratories requiring SOPs, automatic saving and printing, automatic backup, graphical evaluation and LIMS-capable data exchange.
- Security: adds user and password management, audit trail and electronic-signature functions to support validation and regulated workflows associated with FDA 21 CFR Part 11, EC GMP Annex 11 and ISPE GAMP 5. Final system validation remains the user’s responsibility within its quality system.
Scope and operating requirements
The documented basic scope includes the selected software package, slotted nozzle, acrylic-glass cover, intake silencer, hammer and brush, and the device connection cable. A suction or vacuum unit must be ordered separately for the air jet sieve machine. An additional diameter-specific adapter is needed for 200 mm or 76 mm sieves; the 200 mm adapter is part number 210051342. Cyclones, vacuum cleaners, adapters and other accessories should be selected for the sample and workflow.
Data and device interfaces
The instrument provides Ethernet, RS-232 and three USB ports. Balance connectivity, data export and software functions depend on the selected software configuration.
Applications
The e200 LS supports powder sieving and particle-size analysis in minerals, chemicals, pharmaceuticals, food and nutrition, cement and construction materials. Sample properties, target particle-size range, sieve dimensions, suction equipment and software requirements should be reviewed together during selection.
