20 cm chrome sieve for sample inspection and testing. This sieve uses a chrome-plated stainless steel frame with a 304 stainless steel mesh and a 20 cm diameter. Mesh options range from 4 to 600 mesh, with aperture sizes varying accordingly. Durable construction and safe handling. The chrome-plated frame with a thickened, double-layer mesh provides strong resistance to deformation and long service life. Smooth edges ensure comfortable, safe handling during use. Wide range of applications. Suitable for plastics, aluminum, zinc, metal ash, fruit, screws, medicine, grain, dehydrated vegetables, powder, sand, soil, and more. It is applicable across food, industrial, textile, shipbuilding, metallurgy, petroleum, coal, water treatment, pharmaceutical, mineral processing, and related industries. Specifications. Color: as pictured. Frame material: chrome-plated. Mesh material: 304 stainless steel. Diameter: 20 cm. Mesh range: 4–600 mesh (aperture sizes vary by mesh). Use scenarios. - In a quality-control lab, separate powder or granule samples into size fractions for analysis. - On production lines, verify particle size distribution of powders, grains, or pellets. - In environmental or civil testing, sieve soil or sand samples for texture and composition analysis.
