Fisher 8" No. 45 test sieve with a 355 µm (0.0139 in) opening is an industrial-grade tool designed for sieve analysis of materials. The 8-inch diameter and No. 45 designation specify a precise 355 µm opening for consistent particle-size classification in laboratory testing. This Fisher-branded sieve is intended for standard testing procedures that require a No. 45 mesh size, enabling reliable separation of particles by size.
