10in, No. 400 (38µm) Polyester Square is designed to fit non-metallic or brass two-part frames. Square cloth has a circle of tough, resilient material embedded in the mesh to act as a sealing gasket. Opening sizes are equivalent to ASTM E11 sizes but may not meet tolerance specifications.
The versatile polyester material is suitable for most applications because it resists abrasion, acids, and most alkalis up to a pH of 9-10 while maintaining strong wet stability.
