Gilson SS-14 / SS-14F / SS-14D / SS-14DF 8-inch and 12-inch Mechanical & Digital Timer Sieve Shakers

Overview

The Gilson SS-14, SS-14F, SS-14D, and SS-14DF Sieve Shakers are precision-engineered laboratory instruments designed for standardized particle size distribution analysis via dry mechanical sieving. Operating on the principle of orbital horizontal motion—combined with a controlled tilt angle—the shakers generate uniform, low-amplitude agitation that promotes even sample dispersion across sieve surfaces without segregation or over-compaction. This motion profile is specifically optimized to meet the dynamic requirements of ASTM E11 and ISO 3310-1 test methods for sieve analysis of granular materials including soils, aggregates, powders, catalysts, pharmaceutical excipients, and industrial minerals. The shakers accommodate both full-height and half-height sieve stacks across two standard diameters—8 in (203 mm) and 12 in (305 mm)—ensuring compatibility with globally recognized sieve frame dimensions and mesh specifications.

Key Features

• 1/4 HP continuous-duty induction motor delivering consistent, vibration-isolated orbital motion across the full operational range (No. 4 to No. 200, i.e., 4.75 mm to 75 µm)
• EZ-Clamp™ quick-lock system: single-action push-to-engage vertical clamping rod with integrated lid; twist-to-lock mechanism secures multi-tier sieve stacks reliably and reproducibly
• Expandable stack architecture supporting up to 10 full-height 8-in sieves or 21 half-height 8-in sieves per run—maximizing throughput while maintaining ASTM-defined amplitude and frequency stability
• Dual timer configurations: robust electromechanical timer (SS-14/SS-14F) with repeatable stop timing and “hold” continuous-run mode; or advanced digital timer (SS-14D/SS-14DF) featuring large 0.5-in (12.7-mm) red LED display, ±1-second accuracy, programmable pause/resume, and 5-second audible alert at cycle completion
• Universal voltage compatibility: 115 V / 60 Hz (North America, Japan) and 230 V / 50 Hz (EU, UK, Australia) variants certified to IEC 61000-6-3 EMC and IEC 61000-6-2 immunity standards

Sample Compatibility & Compliance

These shakers are validated for use with ASTM E11-compliant wire cloth sieves (stainless steel, brass, or phosphor bronze) and ISO 3310-1-certified test sieves in diameters of 200 mm, 203 mm (8 in), 300 mm, and 305 mm (12 in). They support both full-height (standard depth) and half-height (shallow) frames—enabling flexible method development for fine powders requiring extended dwell time or coarse aggregates needing high-energy stratification. All models comply with ASTM D6913 (soil particle-size analysis), ASTM C136 (aggregate gradation), and ISO 2591-1 (general sieving procedures). The mechanical design meets GLP documentation requirements for instrument qualification: serial-numbered calibration plates, traceable motor performance logs, and user-accessible maintenance records are supported through Gilson’s IQ/OQ documentation kits.

Software & Data Management

While the SS-series shakers operate as standalone hardware devices, their digital timer variants (SS-14D/SS-14DF) integrate seamlessly into regulated environments via audit-trail-ready operation. The digital controller retains last-used settings—including duration, pause history, and alert status—in non-volatile memory. Though no proprietary software is required, the timer’s discrete start/pause/resume inputs allow synchronization with external LIMS or ELN systems via dry-contact relay outputs (available as optional accessory module). All units ship with a Certificate of Conformance stating compliance with IEC 61010-1 for electrical safety and include traceable factory calibration data aligned to NIST-traceable reference sieves. For FDA-regulated labs, the digital timer supports 21 CFR Part 11-compliant workflows when paired with Gilson’s optional electronic logbook add-on (sold separately).

Applications

• Geotechnical laboratories performing ASTM D2487 soil classification and D6913 gradation testing
• Construction materials QA/QC labs validating aggregate conformity per ASTM C33 and EN 12620
• Pharmaceutical R&D labs conducting USP particle size distribution studies on APIs and blends
• Ceramics and battery material producers screening cathode/anode powders per ISO 13320 laser diffraction correlation protocols
• Environmental testing facilities analyzing sediment composition under EPA Method 1684

FAQ

What sieve standards are supported by the SS-14 series?
ASTM E11 and ISO 3310-1 test sieves in 8 in (203 mm), 200 mm, 12 in (305 mm), and 300 mm diameters—both full-height and half-height configurations.
Can the same unit operate on both 115 V/60 Hz and 230 V/50 Hz?
No. Voltage/frequency configuration is fixed per model: SS-14 and SS-14D are 115 V/60 Hz; SS-14F and SS-14DF are 230 V/50 Hz. Field conversion is not supported.
Is calibration documentation included?
Yes—each unit ships with a Certificate of Conformance and factory calibration report referencing NIST-traceable sieve standards and motor performance verification.
Does the EZ-Clamp system require tools for adjustment?
No. The clamp engages and locks via manual push-and-twist action; no wrenches, levers, or torque tools are needed.
Are replacement timers available as field-serviceable components?
Yes—mechanical and digital timer assemblies are modular and replaceable under Gilson’s authorized service program with documented calibration revalidation support.
