Overview
The Gilson SS-14F is a precision-engineered mechanical-timer sieve shaker designed for standardized particle size distribution analysis in geotechnical, aggregate, concrete, and soil testing laboratories. Operating on the principle of orbital shaking—where a horizontal circular motion combined with controlled tilt ensures uniform sample dispersion across sieve surfaces—the SS-14F delivers high reproducibility in dry sieving procedures per ASTM C136/C136M, ASTM D6913, ISO 17892-4, and EN 933-1. Its robust ¼ HP induction motor provides consistent energy input across the full operational range (4–200 mesh), enabling reliable separation of free-flowing granular materials from coarse aggregates (4.75 mm) down to fine silt fractions (75 µm). The unit accommodates both ASTM-standard 8-inch (203 mm) and 12-inch (305 mm) diameter test sieves—including ISO 200 mm and 300 mm frames—making it compatible with globally accepted sieve series without adapter modification.
Key Features
- Orbital shaking action with adjustable tilt angle ensures even sample distribution and minimizes blinding or clogging of sieve apertures.
- EZ-Clamp™ quick-lock system: one-button vertical actuation followed by quarter-turn locking secures stacked sieves firmly; integrated lid slides freely during clamping and remains in position post-test for rapid setup continuity.
- Dedicated mechanical timer with repeatable stop timing and “Hold” continuous-run mode—ideal for routine QA/QC workflows requiring fixed-duration cycles.
- Extended stack height supports up to 10 full-height 8-inch sieves or 6 full-height 12-inch sieves; alternatively, up to 21 half-height 8-inch or 14 half-height 12-inch sieves per single run.
- Universal sieve compatibility: accepts standard ASTM E11 and ISO 3310-1 frames in diameters of 8 in (203 mm), 200 mm, 12 in (305 mm), and 300 mm—enabling seamless integration into existing lab sieve inventories.
- Sturdy steel frame with non-slip rubber feet and reinforced base structure ensures vibration isolation and long-term dimensional stability under repeated loading.
Sample Compatibility & Compliance
The SS-14F is validated for use with dry, non-cohesive, and moderately cohesive particulate materials including crushed stone, sand, gravel, slag, fly ash, and milled mineral powders. It complies with mechanical requirements outlined in ASTM D6913 (Standard Test Methods for Particle-Size Distribution of Soil), ASTM C136 (Sieve Analysis of Fine and Coarse Aggregates), and ISO 17892-4 (Geotechnical Investigation and Testing — Laboratory Testing of Soil — Part 4: Determination of Particle Size Distribution). While not intrinsically compliant with GLP or FDA 21 CFR Part 11, its mechanical timer design supports audit-ready traceability when paired with laboratory-controlled SOPs documenting operator, date, duration, and sieve stack configuration.
Software & Data Management
As a fully mechanical instrument, the SS-14F does not incorporate embedded software, microprocessors, or digital data logging capabilities. This architecture eliminates firmware dependencies, cybersecurity vulnerabilities, or calibration drift associated with electronic controllers—enhancing long-term reliability and reducing total cost of ownership. All timing operations are performed via calibrated mechanical cam-and-gear assembly, ensuring zero dependency on external power fluctuations or software updates. Laboratories requiring electronic documentation may integrate the SS-14F into broader LIMS environments via manual entry or barcode-scanned test records aligned with standardized sieve analysis templates.
Applications
- Aggregate gradation testing for asphalt and concrete mix design (ASTM C33, AASHTO M6/M80).
- Soil classification per Unified Soil Classification System (USCS) and AASHTO M145.
- Quality control of industrial minerals, ceramics, and pharmaceutical excipients where sieve-cut validation is required.
- Educational labs performing foundational particle size analysis experiments with emphasis on repeatability and procedural fidelity.
- Field-deployable testing stations where electrical simplicity and ruggedness outweigh advanced automation needs.
FAQ
What voltage configurations are supported by the SS-14F model?
The SS-14F is configured for 230 V, 50 Hz operation and is intended for international markets outside North America. For 115 V, 60 Hz applications, specify model SS-14.
Can ISO 200 mm and 300 mm sieves be used interchangeably with ASTM 8-inch and 12-inch frames?
Yes—the SS-14F’s universal mounting platform accepts both ISO and ASTM frames without adapters due to identical flange geometry and clamping interface tolerances.
Is the mechanical timer field-calibratable?
No—timing accuracy is factory-set and maintained through precision-machined gear trains; periodic verification against a certified stopwatch is recommended per laboratory quality protocols.
What is the maximum allowable stack weight?
The shaker supports up to 25 kg (55 lb) of total stack mass, inclusive of sieves, retainers, and sample—well within the structural limits for full-height 12-inch stacks.
Does Gilson offer service contracts or extended warranties for the SS-14F?
Yes—authorized distributors provide optional 2-year extended warranty packages covering motor, drive mechanism, and mechanical timer assembly, subject to regional availability and terms.
