Laboratory sieve shaker for accurate particle size analysis
Streamline your material testing with a robust vibratory sieve shaker designed for efficient particle size analysis, ensuring precise separation and consistent results in both dry and wet sieving applications.

The AS 450 basic from Retsch is an economical vibratory sieve shaker designed to address the precise requirements of particle size separation in industries like chemicals, construction, and environment/recycling. Employing an electromagnetic drive, it utilizes a 3D throwing motion for superior particle distribution over the sieving area, ensuring high separation efficiency even during short sieving times. Capable of handling up to 15 kg of material, it supports both dry and wet sieving applications, making it versatile for various batch operations. With digitally adjustable parameters such as time and amplitude, users can achieve optimal results tailored to their specific needs. Constructed with robust steel housing, it offers maintenance-free operation while accommodating a maximum sieve stack mass of 50 kg. Designed for laboratory environments, it integrates seamlessly into manual and high-speed operational workflows, providing reliability across a range of applications, from cement and powders to ores and plastics.
