RETSCH AS 450 Control Vibratory Shaker

RETSCH AS 450 Control Vibratory Shaker — Precision Sieving for Labs & QC

The RETSCH AS 450 Control Vibratory Shaker is a high-capacity analytical sieve shaker designed for research and development, quality control of raw materials, intermediate products, finished goods, and production monitoring. Its controllable electromagnetic drive and patented CET Technology deliver precise and reproducible sieve analysis results. 

This advanced sieve shaker excels with three-dimensional sieving motion, allowing both dry and wet sieving with consistently sharp fractions — even with short sieving times and heavy loads. 

For labs needing an economical sieve shaker alternative, the RETSCH AS 200 Basic Sieve Shaker is a reliable option. 

How the AS 450 Control Works

At the core of the AS 450 Control is RETSCH’s Continuous Energy Transfer (CET) Technology. This patented electromagnetic drive generates high amplitude — up to 2.2 mm even with a maximum load of 25 kg — which exceeds the capabilities of conventional electromagnetic or imbalance drives. 

The electromagnetic system continuously vibrates the sieve stack, transmitting energy to the sieve plate with a controlled 3D throwing motion. This movement spreads material evenly across the entire sieve surface and enhances separation efficiency and reproducibility. 

Key Features & Advantages

• Works for dry and wet sieving applications
• Excellent separation efficiency with short sieving times
• Patented CET Technology for controlled amplitude under heavy load
• Up to 14 fractions in a single run
• Digital adjustment of time, amplitude, and interval settings
• Memory for up to nine SOPs
• Mobile operation panel for easy control
• Optional EasySieve software for result documentation and evaluation
• Compliance with ISO 9001 standards
• Ergonomic design and low maintenance ■ 

Typical Applications

The AS 450 Control is suitable for a wide range of materials, including:

cement clinker, chemicals, coal, coke, construction materials, fillers, minerals, ores, plastics, sand, and soils. 

This broad application range makes it valuable in industries such as mining, materials testing, construction QA/QC, environmental labs, and manufacturing quality assurance.

Operation & Ease of Use

The intuitive user interface and mobile control panel simplify operation, making setup and parameter adjustments efficient and error-free. The ergonomic design reduces operator fatigue, while low noise and stable motion enhance laboratory conditions.

To expand your lab’s sieving capabilities, explore other sieve shaker models like the RETSCH AS 300 Sieve Shaker Control, which provides similar 3D throwing motion and digital controls. 

Maintenance & Longevity

Regular maintenance ensures maximum performance and long service life. Clean sieves and stack components after each run, inspect the electromagnetic drive periodically, and follow recommended lubrication schedules for moving parts.

Certified MTP also offers essential accessories for sieving applications, such as RETSCH O-Rings for Sieves to secure sieve stacks during operation. 

Why Choose the AS 450 Control

With its powerful electromagnetic drive, advanced CET Technology, and flexible digital controls, the RETSCH AS 450 Control Vibratory Shaker is ideal for laboratories and production environments that require accurate, repeatable sieve analysis — even with large loads and complex samples.

Whether you’re conducting routine quality control or complex R&D testing, this shaker delivers efficiency, reproducibility, and ease of use.
