ヴァーダー・サイエンティフィック株式会社 Product Lineup

The electromagnetic sieve shaker from Retch is used not only for research and development, quality control of raw materials, work-in-progress, and products, but also for monitoring production processes. The AS200 series offers three models tailored to different purposes and budgets. For higher processing volumes, the AS300 Control can handle up to 6 kg, while the AS450 Control can accommodate up to 20 kg. It can perform both dry and wet sieving. The "Control" type models are sieve shakers that can be adjusted not only for amplitude but also for "acceleration at the sieve bottom," allowing for high reproducibility even across regions with different power supply frequencies. Additionally, all "Control" types can be calibrated, making them suitable for quality management in compliance with ISO9000. Retch holds a patent (EP0642844) for the electromagnetic drive system used in the AS200, AS300, and AS450 models. This drive generates a three-dimensional shaking motion, evenly shaking samples across the entire mesh surface. As a result, it can withstand loads, operate quietly, and efficiently classify samples in a short amount of time.

A tap-type electromagnetic sieve shaker has been released from Retsch. It combines a horizontal reciprocating motion of 280 times per minute with a tapping motion of 150 times per minute from above, making it easier for samples to pass through the sieve mesh. A dedicated soundproof case is also available to reduce noise.

The "AS400" is a horizontal rotary sieve shaker used not only for production monitoring but also for research and development, quality control of raw materials, intermediates, and products, as well as product inspection. It can accommodate test sieves with an outer diameter of up to 400 mm and allows for dry sieving. With stable horizontal motion, it can precisely classify samples from coarse to fine. All operations are digitally controlled, ensuring precise and comfortable usability. It complies with ISO9001 guidelines. 【Features】 ■ Horizontal rotary motion in accordance with DIN53477 ■ Efficient sieving in a short time ■ Up to 9 operating conditions can be registered ■ Intermittent operation possible ■ Maintenance-free ■ Compatible with optional software EasySieve via RS232, suitable for classification evaluation and documentation *For more details, please refer to the PDF materials or feel free to contact us.

The "AS200tap" is a tap-type sieve shaker that is standardized for the classification of materials such as activated carbon, abrasives, iron powder, spices, and diamonds.
