AS-200
Laboratory Sieve Shaker.
The AS-200 Basic Laboratory Sieve Shaker is a compact, high-performance system for reproducible particle-size analysis and material separation. Suitable for both dry and wet sieving, it is designed to deliver efficient and consistent results, even with short sieving times.
Using a patented electromagnetic drive, the AS-200 produces a three-dimensional throwing motion that distributes material evenly across the entire sieve surface. This motion supports effective separation, optimum utilisation of the sieve openings, and reliable particle-size classification for laboratory, R&D, and quality-control applications.
Key Features
- Laboratory sieve shaker for dry and wet sieving
- Patented electromagnetic drive system
- Three-dimensional throwing motion with angular momentum
- Uniform product distribution across the full sieve surface
- Digitally adjustable sieving time and movement

Operating Principle
The AS-200 operates through an electromagnetic drive that creates a controlled 3D throwing motion. This movement causes the sieve stack to oscillate horizontally while also generating vertical motion and angular momentum.
As a result, the sample is distributed evenly over the sieve surface, helping particles pass through the appropriate mesh openings efficiently. The process supports accurate separation into multiple particle-size fractions.
Applications
The AS-200 Basic is suitable for:
- Particle-size analysis
- Dry sieving of powders and solid particles
