Durable 3in (76mm) Non-Metallic Sieves are hand-made by Gilson for special applications and have clear polycarbonate frames.
Mesh and frame assembly is secured with heat-cured acrylic cement and silicone sealant. Polyester mesh has opening sizes matching U.S. Standard series from No. 50 (300µm) to No. 635 (20µm), as well as 7, 10 and 15µm. These sieves have approximately 1-3/4in (45mm) overall height, 1-1/4in (32mm) stacked height and 2-7/8in (73mm) inside diameter.
An elastic polyolefin band covers the frame joint and provides an effective wet-sieving seal when nesting. Sieves are autoclavable and microwavable for drying. Transparent frames make it easy to visually monitor specimen performance during separation or liquid levels during wet-sieving operations. These sieves don’t nest with standard metallic sieves.
