20 cm Chrome-Plated Sieve with 304 Stainless Steel Mesh - Durable construction: chrome-plated frame with a double-layer thickened mesh rim provides high stiffness, long-lasting rigidity, and resistance to deformation. - Chrome-plated stainless steel mesh: the sieve uses a 304 stainless steel mesh for strength and corrosion resistance, with a chrome-plated frame for added durability. - Safe and user friendly: smooth edges reduce the risk of hand injury during handling and use. - Wide compatibility and performance: designed for sample inspection and testing across a range of materials and processes. Suitable for particle size separation and QC in plastics, metals, minerals, food, pharmaceuticals, and more. - Adjustable mesh options: diameter 20 cm with mesh openings from 4 mesh to 600 mesh (corresponding aperture sizes vary by option). - Comprehensive specifications: color as pictured; frame material chrome; lower net material 304 stainless steel mesh; diameter 20 cm; mesh options from 4 to 600 mesh. Common use scenarios: - Lab sample screening and particle size analysis for powders, sands, soils, and minerals. - Quality control in manufacturing and processing of plastics, metals, grains, and dehydrated products. - Pre-screening and material separation in food, pharmaceuticals, textiles, and industrial applications.
