LABALPHA Test Sieve 4 in. Diameter Sizes 700 and 1200 Mesh Set of 2 Sieves

LABALPHA 4-Inch Ultra-Fine Precision Test Sieve Set (700 Mesh / 18 µm & 1200 Mesh / 10 µm). A dual-sieve set of precision-woven stainless steel analytical sieves engineered for micro-particle separation, quality control gradation, and ultra-fine particulate fractionation in laboratory and industrial powder metallurgy workflows.

• Set Configuration & Quantity: Set of 2 ultra-fine test sieves:
  • Sieve 1: 700 Mesh (nominal aperture ~18 µm / 0.018 mm)
  • Sieve 2: 1200 Mesh (nominal aperture ~10–13 µm / 0.010–0.013 mm)
• Frame Dimensions: 4.0-inch (approx. 100 mm / 10 cm) outer diameter with standard half-height profile (~4.5 cm / 1.77" total frame depth), optimized for benchtop testing, compact stack shakers, and minimal sample retention
• Metallurgy & Material Construction: Fully fabricated from premium AISI 304 stainless steel, including both the seamless double-layer spun frame and the micro-woven wire mesh screen, providing high chemical resistance, oxidation tolerance, and wide thermal stability
• Weave & Aperture Uniformity: Precision twill dutch / square micro-weave wire cloth engineered with consistent aperture geometry to prevent irregular bypass and maintain reproducible separation cutoffs at sub-20-micron thresholds
• Frame Engineering: Deep drawn, double-wall interlocking nesting frame design featuring smooth interior transitions and crevice-free seam joins to eliminate material entrapment and facilitate complete sample recovery
• Stacking & Equipment Interfacing: Standard nesting skirt allows secure modular stacking with compatible 4" collection receiving pans, sieve covers, and mini vibratory or sonic sieve shakers
• Maintenance & Cleanability: Fully autoclavable and ultrasonic bath compatible; recommended for gentle immersion ultrasonic cleaning to clear blinded apertures without distorting delicate micro-wires
• Primary Application: Micro-powder classification, additive manufacturing metal powder quality control, abrasive grading, ceramic slip analysis, toner and pigment particle sizing, soil colloid fractionation, and fine particulate air/liquid filtration
