Aode Aode-200A Electromagnetic Vibratory Sieve Analyzer

Overview

The Aode Aode-200A Electromagnetic Vibratory Sieve Analyzer is a laboratory-grade mechanical particle size analyzer engineered for precise, reproducible dry and wet sieving of powders and granular solids. It operates on the principle of electromagnetic-driven triaxial vibration—generating controlled, high-frequency throwing motion that disperses particles uniformly across the sieve surface while dislodging near-size particles temporarily occluding apertures. This physical separation mechanism adheres strictly to standardized sieve analysis protocols defined in ISO 3310, ASTM E11, and Ph. Eur. 2.9.38, making it suitable for regulatory-compliant quality control in pharmaceutical, chemical, metallurgical, and materials science laboratories. Unlike rotary or horizontal shakers, the Aode-200A’s electromagnetic actuator delivers consistent energy input without mechanical wear, ensuring long-term measurement stability and minimal maintenance.

Key Features

• Electromagnetic 3D excitation system enabling repeatable triaxial throwing motion—critical for breaking particle agglomerates and preventing blinding of fine-mesh sieves.
• Programmable amplitude (0.2–3 mm) and frequency (3000–3600 rpm) to optimize separation efficiency across diverse material types—from cohesive APIs to abrasive mineral sands.
• Modular sieve stack configuration supporting up to 16 layers of ISO/ASTM-standard 203 mm-diameter sieves (25 mm height) or 10 layers (50 mm height), accommodating multi-fraction grading protocols.
• Integrated SMART Sieve Analysis software with full GLP-aligned data handling: automatic mass input via RS-232 balance interface, real-time calculation of fractional residue, cumulative passing rate, and mass loss %.
• Dual-tier user access control (Administrator/Operator) with password protection, session logging, and immutable audit trail compliant with FDA 21 CFR Part 11 requirements for electronic records.
• Full stainless-steel (AISI 304) construction of all wet-contact components—including sieve frames, clamps, and collection pans—for corrosion resistance and cleanability under GMP conditions.
• Transparent polycarbonate viewing lid and inter-layer inspection rings enable visual validation of particle flow dynamics and sieve loading uniformity during operation.

Sample Compatibility & Compliance

The Aode-200A accommodates a broad spectrum of particulate materials including active pharmaceutical ingredients (APIs), excipients, metal powders, ceramic precursors, catalysts, soil aggregates, foundry sands, and food-grade particulates (e.g., flour, coffee grounds). Its validated measurement range spans 5 µm (with optional ultrasonic assist module) to 25 mm, covering coarse aggregates per ASTM C136 and fine powders per USP . All supplied sieves carry traceable calibration certificates issued by CNAS-accredited metrology institutes, conforming to ISO/IEC 17025. The instrument itself meets electromagnetic compatibility (EMC) standards IEC 61326-1 and electrical safety requirements IEC 61010-1. Routine performance verification follows ISO 2591-1 procedures using certified reference materials.

Software & Data Management

The embedded SMART Sieve Analysis software runs natively on the 7-inch capacitive touchscreen and supports bilingual UI (English/Chinese). It captures raw mass values from connected analytical balances, computes sieve-specific metrics—including fractional retention (%R_i), cumulative retention (%R_cum,i), and passing rate (%P_i)—and plots normalized granulometric distribution curves (dF/d(log x) vs. particle size). Export formats include CSV (for LIMS integration), PDF test reports with digital signatures, and PNG vector graphics. Data files retain full metadata: operator ID, timestamp, method name, sieve sequence, environmental temperature/humidity (if external sensor connected), and version-stamped firmware revision. No proprietary file locking: all datasets are human-readable and interoperable with third-party statistical tools (e.g., JMP, Minitab).

Applications

This analyzer serves as a primary tool for QC release testing in pharmaceutical manufacturing (e.g., granule sizing prior to tablet compression), raw material qualification in specialty chemicals, particle size specification verification for additive manufacturing feedstocks, and research-grade classification of nanocomposite precursors. It is routinely deployed in university teaching labs for ASTM D6913 soil gradation studies, in paint R&D for pigment dispersion assessment, and in cementitious materials labs for fineness modulus determination per ASTM C204. Its ability to handle 6 kg batch loads makes it equally viable for pilot-scale process development where representative sampling is essential.

FAQ

Does the Aode-200A support wet sieving?
Yes—it is equipped with sealed drive housing and corrosion-resistant stainless-steel components compatible with aqueous or solvent-based suspensions per ISO 2591-2.
Can sieve calibration certificates be provided for audit purposes?
Each sieve set ships with a CNAS-traceable certificate referencing ISO/IEC 17025, including aperture measurement uncertainty at 95% confidence level.
Is the software compliant with 21 CFR Part 11 for electronic signatures?
The system supports role-based electronic signatures, audit trail archiving, and data integrity safeguards required for regulated environments.
What is the maximum allowable moisture content for dry sieving?
Samples must contain ≤0.5% free moisture to prevent adhesion-induced bias; higher moisture content requires wet sieving or pre-drying per ISO 8502-2.
How frequently should performance verification be performed?
Daily verification using a certified reference standard (e.g., NIST SRM 1990) is recommended before critical batch testing, with full recalibration every 6 months or after 500 operating hours.
