Durable 3in (76mm) Non-Metallic Sieves are hand-made by Gilson for manual use with small volumes of fine materials. Clear polycarbonate frames allow observation of samples during agitation. Polyester mesh has opening sizes matching the U.S. Standard series from No. 50 (300µm) to No. 635 (20µm), as well as 7, 10, and 15µm sizes. These sieves have approximately 1-3/4in (45mm) overall height, 1-1/4in (32mm) stacked height, and 2-7/8in (73mm) inside diameter.
Mesh and frame assembly is secured with heat-cured acrylic cement and silicone sealant. An elastic polyolefin band covers the frame joint and provides an effective seal when nesting. Sieves are autoclavable for cleaning between uses. These sieves will nest with each other, but not with other sieve types.
