Suitable for a wide range of materials including fruit powder, dehydrated vegetable powder, tea, grain, aluminum, and other metal screws, sand, soil and more. Versatile for laboratory, farm and home filtration uses. Specifications and features Material: 304 stainless steel Diameter: 20 cm (7.87 inches) Mesh set: 4, 10, 20, and 60 Design: stackable with tightly secured wire cloth for reliable performance Applications Food and agricultural testing: sieving fruit powders, dehydrated vegetable powders, tea, and grains to achieve specified particle sizes. Metal and material screening: separation of aluminum and other metal screws and related particulates, as well as sand and soil samples. General filtration: suitable for laboratory, farm and home filtration tasks requiring consistent particle separation. Use scenarios In a laboratory, perform routine particle size analysis on tea and grain samples to ensure consistency in quality control workflows. On a farm or in a home setting, filter and classify dried ingredients such as fruit or vegetable powders to prepare uniform stock for processing or cooking. In an industrial or workshop context, classify sand or soil samples, and screen aluminum parts or metal debris for sorting and preliminary analysis.
