A Test Sieve is a laboratory instrument designed for particle size separation and analysis of powders, granules, and bulk materials. Manufactured from high-grade stainless steel, it consists of a rigid circular frame fitted with precision-woven wire mesh of specific aperture size. Test sieves are commonly used in pharmaceutical, chemical, food processing, construction, and research laboratories to ensure material consistency and compliance with quality standards. They are compatible with sieve shakers for mechanical sieving and can also be used manually for small-scale testing. The sieves are manufactured in accordance with international standards to ensure dimensional accuracy and reliable performance.
