Micro-Mesh Sieves
Precision Micro-Mesh® Sieves
Micro-Mesh® sieves, crafted from electroformed material, are designed for precise particle separation. Available in various standard frame diameters, these sieves are perfect for sorting, sifting, screening, and classifying materials by particle size and shape. Their smooth, flat surface minimizes clogging and facilitates easy cleaning, ensuring high product quality in both laboratory and manufacturing settings.
Our Nickel Micro-Mesh sieves come in square, round, slotted, and custom apertures, with mesh sizes starting from 2 microns. These sieves, approximately .001" thick, can be supported or unsupported. The stainless-steel support grid options include configurations of 2.5, 5, and 14 lines per inch.
Frames are available in stainless steel and acrylic, including metric sizes. To request a Sieve Quote, please use our simple on-line request form.

Precision Sieves and Accessories
Support Grid Recommendations
- For particles > 1000 microns, use a 2.5 lines per inch grid.
- For particles between 20 and 1000 microns, use a 5 lines per inch grid.
- For particles < 20 microns, use a 14 lines per inch grid.
Pans, Covers, and Nesting Pans
If you're using our sieves for sequential particle sizing, consider our Micro-Mesh sieve accessories. We offer matching pans, covers, and nesting pans to complete your classification systems. All accessories, including sieve frames, are made from high-quality stainless steel. Pans and covers are available as a set, while nesting pans can be purchased separately.
Sieve Certifications
Our Micro-Mesh sieves comply with ISO specifications 3310-3 and 3310-1, as well as ASTM specification E-161-00. Each sieve is measured at 108 random locations using automated optical measuring equipment and comes with a comprehensive analysis and certificate of compliance.
Custom Sieve Material
Need custom sieve material? We provide Micro-Mesh sieve material in sheets ranging from 3" square to 12" square. Custom sizes are available from 3 microns to 2000 microns in single micron increments. We offer various aperture shapes including square, round, slotted, and hexagonal. Our sieve material is made from nickel and adheres to the same high standards. Sheets come with a 5 lines per inch support grid, unless specified otherwise.
