Need to sort materials by size in a lab, workshop, farm, or even at home? This is a professional-grade 12-inch (30cm) diameter test sieve. The mesh screen is made from durable 304 stainless steel, which means it won't rust, can handle high temperatures, and resists corrosion from many chemicals. The aperture size (the holes) is 4 mesh, which translates to holes about 4.75 millimeters across.\n\nThe frame is sturdy with a double-layer construction and has smooth edges, so it's safe to handle and stacks neatly with other sieves if you buy a set. This 12-inch size is larger than many standard lab sieves, giving you a bigger screening area to work with faster.\n\nYou can use it for all sorts of things: sifting soil or compost in the garden, grading grains or beans in the kitchen, separating different sizes of sand or gravel, sorting plastic pellets, or checking metal powders in an industrial setting. It's a versatile, heavy-duty tool.\n\nJust a super important tip before you buy: Double and triple-check that the '4 Mesh / 4.75mm' opening size is what you actually need for your project. The seller offers many other mesh sizes (from 3 mesh all the way up to 2800 mesh), so if you need a finer or coarser screen, make sure to look for the right listing. A reliable, simple tool for anyone who needs to classify materials by particle size.
