Gilson SS-14D 8-inch / 12-inch Digital Timer Vibratory Sieve Shaker

Overview

The Gilson SS-14D is a precision-engineered vibratory sieve shaker designed for standardized particle size distribution analysis in geotechnical, aggregate, pharmaceutical, and materials testing laboratories. It operates on the principle of orbital shaking—generating a controlled horizontal elliptical motion that ensures uniform sample dispersion across the sieve surface while minimizing particle segregation and blinding. This mechanism complies with core mechanical vibration requirements specified in ASTM E11, ASTM C136/C136M, ISO 3310-1, and EN 933-1 for sieve analysis. The unit accommodates both 8-inch (203 mm) and 12-inch (305 mm) diameter test sieves—including full-height (standard depth) and half-height configurations—enabling high-throughput stacking up to 10 sieves (8-inch) or 6 sieves (12-inch) in a single run. Its robust ¼ HP motor delivers consistent kinetic energy across the full analytical range—from coarse aggregates (No. 4, 4.75 mm) down to fine powders (No. 200, 75 µm)—ensuring reproducible separation performance under GLP-compliant workflows.

Key Features

• Digitally controlled timing system with large 0.5-inch (12.7 mm) LED display, programmable from 1 second to 99 minutes ±1 second accuracy
• Pause/resume functionality preserves elapsed time during mid-cycle interruptions—critical for multi-stage sieving protocols
• EZ-Clamp™ quick-lock system: one-button vertical actuation followed by quarter-turn locking; integrated lid eliminates separate cover handling
• Orbital pan motion (non-vertical agitation) promotes even material distribution and reduces sieve clogging
• Universal sieve compatibility: accepts ASTM E11 and ISO 3310-1 compliant frames in 8-inch (203 mm), 200 mm, 12-inch (305 mm), and 300 mm diameters
• Expandable stack height supports up to 21 half-height 8-inch sieves or 14 half-height 12-inch sieves per run
• Fixed-speed operation optimized for standardized test durations; no variable frequency drive required for ASTM/ISO conformance

Sample Compatibility & Compliance

The SS-14D is validated for use with free-flowing granular solids including soils, crushed rock, sand, cementitious powders, catalysts, and API excipients. It meets mechanical performance criteria outlined in ASTM D6913 (soil particle-size analysis), ASTM C136 (aggregate gradation), and ISO 2591-1. All structural components are fabricated from corrosion-resistant steel and engineered polymers suitable for cleanroom-adjacent environments. Electrical configuration adheres to IEC 61000-6-3 (EMC emissions) and UL 61010-1 (laboratory equipment safety). Units shipped to regulated markets include documentation supporting traceable calibration verification per ISO/IEC 17025 requirements.

Software & Data Management

As a benchtop electromechanical instrument, the SS-14D does not incorporate embedded software or network connectivity. Timing parameters are set via front-panel digital controls with non-volatile memory retention. All operational logs—including duration, pause events, and alarm triggers—are manually recorded per laboratory SOPs. For audit readiness, users may integrate the shaker into broader LIMS or ELN systems using external time-stamped video capture or programmable logic controller (PLC) interfacing via dry-contact relay outputs (optional accessory). The device supports 21 CFR Part 11–compliant data integrity when paired with validated electronic lab notebooks that capture operator ID, timestamped start/stop entries, and environmental metadata.

Applications

• Gradation testing of coarse and fine aggregates per AASHTO T 27 and ASTM C136
• Soil classification and Atterberg limits preparation (ASTM D2487, D422)
• Quality control of powdered pharmaceutical ingredients (USP <786>)
• Particle size verification of metal powders in additive manufacturing feedstock
• Filter media validation and catalyst support screening
• Educational demonstrations of sedimentation theory and sieve analysis fundamentals

FAQ

What sieve standards does the SS-14D support?

It accepts all ASTM E11 and ISO 3310-1 compliant test sieves with nominal diameters of 200 mm, 203 mm (8 in), 300 mm, and 305 mm (12 in).
Can the SS-14D operate continuously without a timer?

No—the digital timer is integral to operation; however, the “Hold” mode allows indefinite runtime until manually stopped.
Is calibration certification included with shipment?

Factory calibration verification documentation is provided; third-party accredited calibration services are available upon request.
What maintenance is required for long-term reliability?

Annual inspection of motor mounts, pan bushings, and EZ-Clamp actuation springs is recommended; no lubrication is required under normal use.
Does the unit comply with EU CE marking requirements?

Yes—units configured for 230 V / 50 Hz include CE marking per Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU.
