The Raise Lab Equipment Electromagnetic Sieve Shaker Model RSS-1 is a pivotal tool in laboratories for particle size analysis with precision, efficiency, and compliance.
Operating Principles
Electromagnetic sieve shakers operate using electromagnetic waves to create vibrations. An electromagnetic drive unit converts electrical energy into mechanical vibrations, generating a controlled and consistent pattern. The drive creates vibrations by oscillating at high frequency, typically between 3,000 and 3,600 vibrations per minute.
Key Specifications
- Sieves constructed from high-quality Stainless Steel-316 (SS-316) for durability and corrosion resistance
- Available in sizes of 100mm and 200mm diameter with heights of 25mm and 50mm
- Adjustable amplitude ranging from 0.5 to 3.0 mm
- Accommodates 100×25 mm sieves (up to 16 sieves) and 200×50 mm sieves (up to 8 sieves)
Advantages Over Traditional Shakers
- Improved Separation Efficiency: Consistent, precise shaking motion enhances accuracy
- Reduced Sample Loss: Better particle control during analysis
- Faster Analysis Times: High-frequency vibration speeds up separation
- Greater Reproducibility: Electronic control ensures consistent results
- Low Maintenance: Fewer moving parts than mechanical shakers
- Quiet Operation: Minimal noise improves laboratory environment
Wet vs. Dry Sieving
The RSS-1 handles both common sieving methods:
- Dry Sieving: For free-flowing materials like granules and coarse powders
- Wet Sieving: Essential for materials that clump or carry static charge, with specialized kit including spray nozzle
Regulatory Compliance
Sieves supplied with the RSS-1 conform to stringent industry standards with individual calibration certificates ensuring accuracy and consistency.
