Economy Test Sieve #7-2.8mm Opening - Chroming Frame - 304 Stainless Steel Wire Cloth for Particle Analysis 1pcs(20cm)

1.The economy test sieve frame are chrome plating steel, is not 304 stainless steel.It is no problem using in dried particles. It also has a long life time maintaining in good conditions.The wire cloth are 304 stainless steel.2.The diameter have 4 options：10cm,20cm,30cm,40cm.3.10cm,20cm,30cm are double chroming steel sheet made by stamping die machine.4.The 40 cm are single layer chroming steel made by man hand for the better straching tigntness than machine.5.About large diameter:Those more than #200 mesh size wire cloth, installed on diameter 40cm, is not as sturdy as those below #200. The reason is the wire cloth difference. The using life is shorter than low mesh size. In , it is not a suggesting solution.
