Analytical Test Sieves

Description

Analytical test sieves are precision instruments used for particle size analysis, manufactured to meet the stringent specifications outlined in ISO 3310. These sieves are constructed using a specialized manufacturing process that ensures consistent quality and dimensional accuracy. Available in common frame sizes such as 200 x 50 mm, 200 x 25 mm, 203 x 50 mm (8"x 2"), and 203 x 25 mm (8"x 1"), they are designed for a measuring range from 20 micrometers to 125 millimeters. The sieves feature a one-piece construction with a smooth fabric transition to minimize areas where particles could become trapped, reducing the risk of cross-contamination between samples. They are fabricated from high-alloy stainless steel, offering corrosion resistance and ease of cleaning. An innovative design makes these sieves approximately 15% lighter than conventional models while providing a larger effective sieving area. Production involves automated processes and thorough optical inspection to maintain quality. A resilient welding technique is employed to ensure the sieve fabric remains securely and permanently attached to the frame. The sieves are designed for stable stacking with effective sealing, and each unit is individually identified with a clear, permanent laser engraving for full traceability.
