Air Jet Sieve e200LS

The iconic Air Jet Sieve e200 LS from Hosokawa Micron is the original pneumatic dry sieving instrument for powder and the most widely used equipment in the world for detecting particle size distributions, production monitoring, industry-standard international quality assurance, batch control, R&D and laboratory testing. We are proud to say that Hosokawa Alpine, our sister company, discovered the ground-breaking methodology behind air jet sieving and innovated the technology in the early 1950s, introducing the first model (A200 LS) in 1953. Since then, this technology-packed, precision piece of desktop laboratory instrumentation has become infinitely more sophisticated and technologically advanced. Today, the Air Jet Sieve e200 LS is trusted by thousands of customers – from the academic, R&D, chemicals, pharmaceuticals, cosmetics, food, agrochemicals and minerals industries – who rely on its wide-ranging capabilities, micro-precise accuracy, high performance, powerful functionality and sophisticated document validation levels, while also favouring its compact, streamlined design and energy-efficient, user-friendly and quiet operation. The Air Jet Sieve e200 LS from Hosokawa has consistently enjoyed a premier market position for seventy years and has recently benefitted from a major technology and features upgrade.


Product Information

The Alpine Air Jet Sieve is a particle size analyser which has been recognised as the technology standard in particle size analysis.

Air Jet Sieve e200LS

It is used for determining the particle size distribution of dry, powdery materials in the range of 25µm to 2000µm.

The simplicity of operation of the Alpine Air Jet Sieve, and technological advances including the integration of a mini computer minimises errors for greater reliability and maintains this product as a market leader. The sieve boasts an innovative HD 6.4in TFT touch screen and the menu is intuitive, making the sieve very easy to operate. It also offers individual language selection.

All the information provided by the particle analyser is easy to understand, including system data and settings. It can be connected to a laboratory balance via USB and Ethernet, and the software is easy and flexible when it comes to upgrades.

Samples between 0.3 and 100 grams can be analysed easily and quickly. The batch weight is dependent on the sieve mesh width and material density, and the sieve offers fully automatic identification of the test sieve mesh widths.

The exceptional dispersion of the material being analysed by the nozzle jet permits analysis down to 10 µm with the micro-precision sieves.

Air Jet Sieve e200LS Specifications

The Air Jet Sieve e200 LS is supplied as a package comprising the instrument itself, a Class L vacuum cleaner and the acrylic glass cover, featuring a special coating that allows for rapid post-analysis cleaning. Customers have a selection of four software packages to choose from and this choice is also included as part of the package (pre-installed for delivery).

Hosokawa’s world-famous Air Jet Sieve (the original A200 LS model) was invented in the 1950s to address the frustratingly common issue of very fine powders agglomerating during the analysis process. The concept and design of the analysis instrument were a scientific revelation for powder processing and today, air jet sieving remains the most accurate way of determining particle size, with Hosokawa’s particle size analysis measurement standards recognised in laboratories, academic institutions and manufacturing industries throughout the world.

The Air Jet Sieve e200 LS is a ground-breaking piece of high-performance laboratory technology that overcomes the challenges of fine powders agglomerating (clumping) during the sieving and analysis process. Originally devised and created by Hosokawa Alpine in the 1950s, it is a fine example of German innovation and craftmanship that has been the market leader for decades.

The iconic instrument performs separation, fractionation and particle size analysis tasks for powders and particles during a set period of time. It offers high reproducibility and comparability, aided by using precision balancing equipment (available separately) to repeatedly weigh the powder throughout the process and using the correct analysis sieve to achieve the results required.

Powerful, effective, reliable and quick, the Air Jet Sieve e200 LS combines the powerful, yet very controlled efforts of two of its important components – the slotted nozzle and industrial Kärcher® vacuum cleaner (optional ATEX-compliant dust collector available).

The narrow, slotted nozzle rotates within the sieving chamber, forcing air through the narrow nozzle holes at a high speed from below – propelling the powder lying on the analysis sieve upwards to make brief, forceful contact with the acrylic glass cover, which quickly disperses the particles – while the vacuum cleaner provides a high vacuum within the chamber.

Suction from the vacuum cleaner draws the powder down through the analysis sieve (if the particles are small enough), separating the fine material from any course material that will remain between the sieve and the glass cover.

When the sieving process is completed, any course material remaining on the analysis sieve in the chamber can be removed and weighed, prior to the process being repeated.

Fine material can be reliably collected via a variety of ancillary products, including the standard issue Kärcher® vacuum cleaner, a fan-assisted DBFV dust extraction vacuum cleaner (ATEX-compliant) or the high-performance, stainless-steel Hosokawa Alpine Cyclone (GAZ 120) for contamination-free extraction of up to 1 litre of fine material.

Automatic under pressure regulation and specifying the sieving parameters guarantee results that can be accurately reproduced.

A suction silencer and new intake duct with optimised air flow design mean the Air Jet Sieve e200 LS is 50% quieter than the previous model.
