Featuring a ultra-fine 600 mesh woven wire cloth woven from high-tensile 304 stainless steel, this sieve delivers an exact 20-micron nominal aperture opening. Constructed with a seamless 4-inch (100 mm) diameter full-height frame, the sieve body is precision-stamped from premium 304 stainless steel to ensure a smooth, crevice-free internal transition that eliminates sample trapping and cross-contamination. Supplied as a lot of 2 matching test sieves, these units are stackable and compatible with standard laboratory sieve shakers, making them an ideal choice for pharmaceutical powder analysis, fine chemical manufacturing, cosmetics QA\/QC, and advanced materials research.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Structural Attributes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUltra-Fine 600 Mesh Woven Wire Mesh: Woven from high-purity stainless steel wire to provide an exact 20-micron nominal aperture for precise sub-sieve micro-particle retention.\u003c\/li\u003e\n\u003cli\u003eSeamless 304 Stainless Steel Frame: Precision-rolled 4-inch frame resists corrosion, chemical attack, and mechanical deformation under continuous vibratory shaking.\u003c\/li\u003e\n\u003cli\u003eCrevice-Free Interior Joint Design: Smooth, continuous solderless transition between mesh and frame wall prevents particle accumulation and enables complete sample recovery.\u003c\/li\u003e\n\u003cli\u003eInterlocking Stackable Architecture: Precision-engineered male and female rim nesting contours allow stable, non-slip stacking with standard 4-inch pans, covers, and intermediate sieves.\u003c\/li\u003e\n\u003cli\u003eEasy-Clean Surface Finish: Smooth metallic finish withstands ultrasonic bath cleaning, organic solvent rinses, and thermal drying cycles up to high temperatures.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePrimary Manufacturer: LABALPHA\u003c\/li\u003e\n\u003cli\u003eEquipment Category: Analytical Particle Sizing \/ Laboratory Test Sieves\u003c\/li\u003e\n\u003cli\u003eMesh Size \/ Aperture Rating: 600 Mesh (20 Micron \/ 0.020 mm Nominal Opening)\u003c\/li\u003e\n\u003cli\u003eFrame Diameter: 4 inches (approx. 100 mm)\u003c\/li\u003e\n\u003cli\u003eFrame Height Profile: Full Height (approx. 1.0 inch \/ 25.4 mm depth to wire cloth)\u003c\/li\u003e\n\u003cli\u003eFrame \u0026amp; Wire Material: 304 Stainless Steel Construction\u003c\/li\u003e\n\u003cli\u003eMesh Weave Type: Twilled Square Weave Precision Wire Cloth\u003c\/li\u003e\n\u003cli\u003eCompliance Standards: Manufactured to meet specifications under ASTM E11 and ISO 3310-1\u003c\/li\u003e\n\u003cli\u003eThermal Stability: Operating range up to 200 degrees C\u003c\/li\u003e\n\u003cli\u003ePackaging Configuration: Lot of 2 Individual Test Sieves\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePharmaceutical \u0026amp; Fine Chemical QA\/QC: Essential for verifying fine powder particle sizes, API bulk density consistency, and excipient fraction distribution.\u003c\/li\u003e\n\u003cli\u003eMetallurgy \u0026amp; Advanced Ceramics: Enables accurate classification of ultra-fine metal powders, ceramic precursors, and 3D printing raw feedstocks.\u003c\/li\u003e\n\u003cli\u003eUltrasonic \u0026amp; Vibratory Shaker Testing: Compatible with benchtop 4-inch electromagnetic sieve shakers for automated dry and wet sieving workflows.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eUsed, in great condition.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003csmall\u003eAll product names, logos, and brands are property of their respective owners.
