Product Overview
Our Brass Test Sieves are specially designed for precise particle size analysis in laboratories where non-ferrous materials are required. Constructed with high-quality brass frames and fine brass or stainless steel mesh, they provide accurate and repeatable sieving results with excellent corrosion resistance.
These sieves are ideal for applications involving light-sensitive materials, fine powders, and when avoiding ferrous contamination is critical — such as in pharmaceutical, chemical, or precious metal industries.
