Lab Test Sieve — 200mm-800mm Diameter, 4-2800 Mesh, Standard Sieving

Lab test sieve for particle size analysis, quality control, and R&D. Available in 200–800 mm diameter with 4–2800 mesh range, compatible with ISO 3310-1 and ASTM E11 standards.

Design Notes

The lab test sieve is a precision instrument for laboratory-scale particle size determination. Unlike industrial vibrating screens, it uses a mechanical shaker or oscillating motion to gently agitate the sample through stacked sieve decks. Each deck carries a different mesh size, so the sample is separated into defined size fractions for analysis.

Frames are constructed from 304 or 316L stainless steel, with precision-woven wire cloth for each deck. The stack is sealed with a lid and collection pan, and the entire assembly is mounted on a mechanical shaker or hand-cranked sieving frame. For ultra-fine materials, we offer ultrasonic-assisted sieves that keep mesh apertures open and maintain consistent cut points.

Typical Applications

• Food industry: flour, sugar, spice, milk powder particle analysis
• Pharmaceutical: API and excipient sieve testing per USP <786>
• Chemical: pigment, resin, additive grade verification
• Mining and geology: soil and sediment particle sizing
• Research labs: material characterization and QC

Why Choose XiaoJiao

XiaoJiao supplies lab test sieves as part of our focused vibrating screen portfolio. We do not manufacture the mechanical shaker units themselves; we supply the sieve frames, mesh, and accessories that integrate with common shaker platforms. Our emphasis is on mesh quality, frame precision, and calibration documentation.

If your duty requires full USP compliance or custom mesh sizes outside the standard range, we can source and certify those items on request.

What You Get

Contact us with your required diameters, mesh specifications, and intended standard (ISO, ASTM, USP). We will return a complete quotation with frame options and lead time.

1. Define your sample size: gram-scale (200-300 mm) vs. larger samples (400-800 mm).
2. Select mesh range: coarse (4-100 mesh) for granules, fine (100-2800 mesh) for powders.
3. Choose number of decks: single deck for overflow analysis, multi-deck for full particle size distribution.
4. Confirm drive type: mechanical shaker for general use, ultrasonic-assisted for ultra-fine materials.
5. Request a quotation with mesh specification, calibration certificate, and frame material option.
