JRY-SF Standard Vibratory Sieve Shaker

Overview

The JRY-SF Standard Vibratory Sieve Shaker is an electromechanical laboratory instrument engineered for precise, reproducible dry and wet sieve analysis in accordance with internationally recognized standards—including ISO 2591-1, ASTM E11, ASTM C136, USP <786>, and EN 933-1. It operates on the principle of horizontal circular vibration, generating controlled orbital motion that imparts kinetic energy to particles resting on stacked standard test sieves. This motion promotes stratification and percolation through aperture openings, enabling quantitative separation of particulate materials by size distribution. Unlike rotary or tapping shakers, the JRY-SF’s consistent 4 mm amplitude and tunable rotational frequency (50–2000 rpm) ensure uniform energy input across the entire sieve stack—minimizing segregation bias and enhancing repeatability between operators and laboratories.

Key Features

• Horizontally circular vibratory drive mechanism with adjustable speed (50–2000 rpm) and digital feedback control for stable, repeatable motion profiles.
• Digital LED display showing real-time rotational speed and programmable timer (0–99 minutes), supporting GLP-compliant time-stamped operation.
• Robust cast-aluminum base and precision-machined stainless steel clamping assembly ensuring long-term mechanical stability and minimal resonance drift.
• Low-noise design (<60 dB[A] at 1 m distance) achieved via balanced motor mounting, elastomeric isolation feet, and optimized gear train damping—suitable for shared lab environments.
• Universal sieve holder compatible with standard ASTM E11 and ISO 3310-1 sieve frames (diameters: 100 mm, 200 mm, and 300 mm), accommodating both dry and wet screening configurations.
• Integrated safety interlock prevents operation unless the sieve stack is fully secured, meeting IEC 61000-6-2 EMC and basic functional safety expectations for Class I lab equipment.

Sample Compatibility & Compliance

The JRY-SF accommodates a broad spectrum of sample types without modification: free-flowing powders (e.g., lactose, silica fume), granular solids (e.g., crushed ore, polymer pellets), friable aggregates (e.g., soil aggregates, pharmaceutical granules), slurries (with optional liquid-tight gasket kits), and even lightly cohesive suspensions when used with wet-sieving protocols. Its 10 µm–30 mm effective sizing range aligns with common industrial sieve series including Tyler, ASTM, and ISO standard mesh tables. The instrument supports compliance workflows for QC/QA departments operating under GMP (21 CFR Part 211), GLP (OECD Principles), and ISO/IEC 17025-accredited testing laboratories—particularly where documented traceability of vibration parameters, duration, and sieve specifications is required.

Software & Data Management

While the JRY-SF operates as a standalone benchtop unit with no embedded PC interface, its digital timer and speed display facilitate manual entry into LIMS or ELN platforms. Users may record operational metadata—including sieve stack configuration (mesh numbers, material type), speed setpoint, duration, ambient temperature/humidity, and operator ID—to support audit-ready documentation. For high-throughput labs, the unit integrates seamlessly with external data loggers via analog voltage output (0–5 V proportional to rpm) or optional RS-232 module (available upon request), enabling automated capture of run parameters into validated software systems compliant with FDA 21 CFR Part 11 requirements.

Applications

• Pharmaceutical development: Excipient particle size distribution analysis per USP <786>; blend uniformity assessment prior to tablet compression.
• Geotechnical & mining labs: Soil gradation testing (ASTM D6913), coal ash fineness evaluation (ASTM C618), and mineral concentrate classification.
• Food & agriculture: Grain size consistency checks for flour, feed pellets, and powdered spices; residue analysis in pesticide screening workflows.
• Materials science: Characterization of ceramic powders, metal AM feedstocks, and battery electrode active materials.
• Environmental testing: Sediment grain-size analysis (ISO 14688-1), landfill cover material specification verification, and fly ash particle fractionation.

FAQ

What sieve diameters and standards does the JRY-SF support?

It accepts 100 mm, 200 mm, and 300 mm diameter test sieves conforming to ASTM E11, ISO 3310-1, and BS 410 specifications.
Can the JRY-SF perform wet sieve analysis?

Yes—when equipped with optional silicone gaskets and a waterproof pan assembly, it supports standardized wet sieving per ASTM C136/C136M and ISO 11277.
Is calibration traceable to national standards?

Speed and timer functions are factory-calibrated using NIST-traceable tachometers and quartz timers; calibration certificates are available upon request.
Does the unit meet electrical safety requirements for international use?

It complies with IEC 61010-1 (Edition 3) for laboratory equipment and carries CE marking for EU markets; UL/cUL listing requires regional certification add-ons.
How is maintenance performed?

Routine maintenance includes periodic inspection of clamping bolts, cleaning of the vibration platform, and lubrication of the eccentric drive shaft every 500 operating hours—no specialized tools required.
