LABALPHA Test Sieve 4 in. Diameter Size 600 Mesh Lot of 2 Sieves

LABALPHA 4-Inch Diameter Precision Test Sieve, 600 Mesh / 20 Micron Aperture, Stainless Steel (Lot of 2 Sieves)

The LABALPHA 4-Inch Precision Test Sieve (600 Mesh) is a high-accuracy particle size separation instrument engineered for fine powder classification, particle size distribution (PSD) analysis, and quality control processing. 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.

Technical Performance & Structural Attributes

• Ultra-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.
• Seamless 304 Stainless Steel Frame: Precision-rolled 4-inch frame resists corrosion, chemical attack, and mechanical deformation under continuous vibratory shaking.
• Crevice-Free Interior Joint Design: Smooth, continuous solderless transition between mesh and frame wall prevents particle accumulation and enables complete sample recovery.
• Interlocking Stackable Architecture: Precision-engineered male and female rim nesting contours allow stable, non-slip stacking with standard 4-inch pans, covers, and intermediate sieves.
• Easy-Clean Surface Finish: Smooth metallic finish withstands ultrasonic bath cleaning, organic solvent rinses, and thermal drying cycles up to high temperatures.
