Overview
The Gilson SS-12RF Tapping Sieve Shaker is an industrial-grade, precision-engineered mechanical sieve shaker designed to perform standardized particle size distribution analysis in accordance with ASTM E11, ISO 3310-1, and USP <786> guidelines. It operates on a dual-mode tapping-and-rotating principle: vertical tapping (48 taps per minute) combined with controlled orbital rotation ensures uniform particle reorientation across the sieve surface—eliminating dead zones common in linear shakers and significantly improving separation efficiency for near-size particles. Unlike conventional reciprocating shakers, the SS-12RF’s patented cyclic rotation promotes three-dimensional particle motion, enabling consistent stratification and improved mesh penetration. Its robust 1/3 HP induction motor, housed in a powder-coated steel chassis, delivers stable, low-vibration operation without requiring floor anchoring—ideal for QC labs, geotechnical testing facilities, and pharmaceutical R&D environments where reproducibility and regulatory traceability are critical.
Key Features
- Dual-action mechanism: 48 vertical taps/min + continuous orbital rotation for enhanced particle dispersion and reduced agglomeration
- Universal compatibility: Accepts both 8 in (203 mm) and 12 in (305 mm) diameter sieves—including full-height, half-height, and ISO 300 mm/200 mm frames via optional adapters
- EZ-Clamp™ quick-release system: One-button actuation secures multi-sieve stacks with axial alignment and repeatable clamping force—no tools required
- Precision digital timer: Programmable test duration from 1 second to 99 minutes 59 seconds, with automatic stop and reset functionality
- Balanced drive architecture: Minimizes operational vibration and extends bearing life; suitable for benchtop use without anchoring
- Electrical variants: Available in 230 V / 50 Hz configuration (SS-12RF), compliant with IEC 61000-6-3 EMC standards
Sample Compatibility & Compliance
The SS-12RF accommodates up to 20 sieves per stack depending on frame height—supporting configurations of thirteen half-height, ten intermediate-height, or six full-height 12 in sieves with receiver pan. Recommended particle size range spans 2 in (50 mm) down to No. 635 (20 µm), though optimal resolution depends on material density, shape, and moisture content. It is fully compatible with ASTM E11-certified wire cloth sieves, ISO 3310-1 stainless steel mesh, and USP-compliant pharmaceutical test sieves. When used with GLP/GMP-aligned SOPs, the device supports audit-ready documentation when paired with validated data capture systems. Optional acoustic enclosure (SSA-805R) reduces ambient noise to ≤65 dB(A) and contains airborne particulates—critical for ISO Class 7 cleanroom-adjacent workflows.
Software & Data Management
While the SS-12RF operates as a standalone electromechanical instrument, its programmable timer enables integration into broader laboratory informatics ecosystems. Time-stamped test logs can be manually recorded into LIMS or ELN platforms supporting 21 CFR Part 11 compliance (e.g., LabWare, Veeva Vault). For automated data linkage, users may pair the shaker with external weighing stations (e.g., Mettler Toledo XPR series) and fraction collectors (e.g., Clean-N-STOR system) to generate complete sieve analysis reports—including mass retained per fraction, cumulative % passing, and D10/D50/D90 calculations. Firmware updates are not applicable; all control logic resides in hardened microcontroller hardware ensuring long-term calibration stability.
Applications
- Aggregate gradation testing per ASTM C136/C136M in civil engineering and asphalt production
- Pharmaceutical granule sizing per USP <786> and EP 2.9.31 for blend uniformity assessment
- Cement fineness evaluation (Blaine air permeability correlation) using standardized sieve trains
- Mineral processing QC—coal, limestone, and phosphate ore classification verification
- Food ingredient particle profiling (e.g., flour, sugar, powdered dairy) under ISO 4793 protocols
- Research-scale nanoparticle dispersion validation when coupled with cascade impactors or laser diffraction pre-screening
FAQ
What sieve diameters and heights does the SS-12RF support?
It natively accepts 12 in (305 mm) full-, intermediate-, and half-height frames, and 8 in (203 mm) frames via included adapter. ISO 200 mm and 300 mm sieves are supported with optional adapters.
Is the SS-12RF compliant with FDA 21 CFR Part 11 requirements?
The unit itself is not electronic-data-generating; however, its deterministic timer output and mechanical repeatability support Part 11–aligned workflows when integrated with compliant data capture systems and audit-trail-enabled software.
Can it be used for wet sieving?
No—the SS-12RF is designed exclusively for dry sieving applications. Wet sieving requires pressurized liquid feed systems and corrosion-resistant housings not present in this model.
What maintenance is required for long-term reliability?
Annual inspection of tap cam followers, belt tension (if equipped with belt-driven variant), and EZ-Clamp spring integrity is recommended. Lubrication is not required—the sealed induction motor and bushed pivot points are maintenance-free per ISO 13374 condition monitoring guidelines.
Does Gilson provide calibration certificates with shipment?
Factory calibration verification is performed pre-shipment; NIST-traceable calibration certificates are available upon request at additional cost and require user-specified reference standards (e.g., certified glass bead sets per ISO 17025).
