LABALPHA Test Sieve 4 in. Diameter Sizes 700 and 1200 Mesh

LABALPHA 4-Inch Diameter Ultra-Fine Precision Test Sieves, 700 Mesh (18 µm) & 1200 Mesh (10 µm)

The LABALPHA 4-Inch Ultra-Fine Precision Test Sieve Set consists of two specialized particle separation instruments engineered for high-accuracy sub-micron powder classification, micro-particle sizing, and advanced quality control testing. This set features two distinct mesh sizes: a 700 mesh sieve (nominal aperture 18 microns) and a 1200 mesh sieve (nominal aperture 10 microns). Constructed with precision-woven micro-wire cloth made from high-tensile 304 stainless steel, these sieves provide clean, accurate cut-offs for fine particulate streams. Each unit features a seamless 4-inch (100 mm) full-height 304 stainless steel frame with a smooth interior transition to prevent sample retention along joint edges. Fully stackable and compatible with ultrasonic and vibratory laboratory sieve shakers, these ultra-fine sieves are designed for pharmaceutical micro-formulation, specialized chemical manufacturing, and advanced powder metallurgy applications.

Technical Performance & Structural Attributes

• Ultra-Fine Precision Wire Cloth: Precision-woven stainless steel mesh provides exact nominal apertures of 18 microns (700 mesh) and 10 microns (1200 mesh) for micro-particulate retention.
• Seamless Stainless Steel Frame: Heavy-duty 304 stainless steel construction resists corrosion, mechanical deformation, and continuous high-frequency vibratory stress.
• Crevice-Free Internal Geometry: Smooth solderless wall-to-mesh transitions eliminate particle trapping zones, ensuring high sample recovery rates during analytical testing.
• Nesting Stackable Rim System: Precision-machined upper and lower frame lips allow secure, non-slip stacking within standardized 4-inch sieve column stacks.
• Ultrasonic Bath Compatible: Designed to withstand repeated ultrasonic bath cleaning, solvent rinses, and high-temperature thermal drying without mesh distortion.
