Air Jet Sieving Machine AS 200 jet
Particle size analysis from 10 µm to 4 mm
The Air Jet Sieving Machine AS 200 jet is particularly suitable for low density and low particle size materials which tend to agglomerate. It is used with sieves of 10 microns mesh size and up. The procedure is very gentle on the material as no mechanical sieving aids are required. The average sieving time is only 2-3 minutes.
The Open Mesh Function, a procedure that greatly reduces the number of near-mesh particles, provides optimum separation efficiency, excellent reproducibility, and longer service life of the sieves.
Process reliability in pharmaceutical research and production
This application note outlines how advanced milling and air jet sieving technologies support process reliability in pharmaceutical research and production. It highlights the importance of precise particle size control in drug development, formulation, and quality assurance, and demonstrates how integrated workflows can improve reproducibility, efficiency, and compliance with GMP requirements. The resource also explores scalable approaches to co-crystal screening and production, from laboratory studies to kilogram-scale manufacturing.
All-in-one reliable particle analysis without sample transfer
In particle analysis, the transfer between sieving machine and balance carries considerable potential for error due to erosion or adhesion. RETSCH has solved this problem with the redesigned AS 200 jet pro and pharma all-in-one air jet sieving machines.
