Gilson SS-14 Advanced Sieve Shaker with Mechanical or Digital Timer

Overview

The Gilson SS-14 Advanced Sieve Shaker is a precision-engineered laboratory instrument designed for standardized particle size distribution analysis in accordance with ASTM E11, ASTM C136/C136M, ASTM D6913, ISO 3310-1, and ISO 2591-1. Utilizing a robust orbital shaking motion—characterized by controlled horizontal displacement and adjustable tilt angle—the SS-14 ensures uniform material dispersion across sieve surfaces, minimizing segregation and maximizing separation efficiency. Its ¼ HP induction motor delivers consistent torque across the full operational range, supporting reproducible sieving of free-flowing granular materials from coarse aggregates (No. 4, 4.75 mm) down to fine powders (No. 200, 75 µm). The unit accommodates both full-height and half-height sieve stacks, enabling high-throughput batch processing without manual reconfiguration between tests.

Key Features

• Orbital shaking mechanism with fixed 8° tilt angle for optimal particle stratification and screen coverage
• Dual-voltage compatibility: 115 V / 60 Hz (SS-14 & SS-14D) and 230 V / 50 Hz (SS-14F & SS-14DF) models available
• EZ-Clamp™ quick-lock system—single-action lever actuation secures full-height or half-height stacks; integrated lid slides vertically for unobstructed access and locks via quarter-turn twist
• Expandable stack capacity: up to (10) × 8-inch (203 mm) full-height sieves or (21) × 8-inch half-height sieves per run
• Motor-driven mechanical timer (SS-14/SS-14F): repeatable stop timing with “Hold” continuous-run mode
• Digital timer variant (SS-14D/SS-14DF): LED-display controller with 0.5-inch (12.7 mm) digits, ±1 second accuracy, 1–99 minute programmable duration, pause/resume function, and audible 5-second completion alert
• Structural frame engineered for low-vibration operation and long-term stability under repeated loading cycles

Sample Compatibility & Compliance

The SS-14 accepts standard ASTM and ISO-compliant test sieves with nominal diameters of 8 in (203 mm), 200 mm, 12 in (305 mm), and 300 mm. It supports both full-height (2 in / 50.8 mm) and half-height (1 in / 25.4 mm) frames, allowing flexible configuration for coarse aggregate gradation (e.g., AASHTO T 27), soil particle analysis (ASTM D422), or pharmaceutical powder characterization (USP ). All operational parameters—including amplitude, frequency, and dwell time—are aligned with GLP-aligned laboratory workflows. The digital timer variant (SS-14D/DF) includes non-volatile memory for parameter retention and supports audit-ready documentation when integrated into validated environments compliant with FDA 21 CFR Part 11 requirements.

Software & Data Management

While the SS-14 operates as a standalone electromechanical instrument, its digital timer variants feature embedded firmware that logs last-used settings (duration, pause status, alarm enablement) and retains them across power cycles. No proprietary software is required for basic operation; however, time-stamped test records can be manually entered into LIMS or ELN platforms using standardized templates aligned with ISO/IEC 17025 documentation practices. For laboratories implementing automated data capture, optional analog output modules (0–5 V DC) are available via Gilson’s accessory interface kit, enabling synchronization with PLC-based QA/QC systems or third-party acquisition software.

Applications

• Aggregate gradation testing for concrete and asphalt mix design (ASTM C136, AASHTO T 27)
• Soil classification and grain-size analysis in geotechnical engineering (ASTM D6913, ASTM D422)
• Quality control of mineral fillers, catalysts, and ceramic powders in manufacturing
• Pharmaceutical excipient screening per USP for particle size uniformity
• Research-grade sieve analysis in academic materials science laboratories requiring traceable, repeatable methodology

FAQ

What sieve diameters and heights does the SS-14 support?

The SS-14 accommodates 8-inch (203 mm) and 12-inch (305 mm) diameter sieves in both full-height (2 in / 50.8 mm) and half-height (1 in / 25.4 mm) configurations.
Is the SS-14 compliant with ISO 3310-1 and ASTM E11 standards?

Yes—the mechanical design, motion profile, and timing accuracy meet the performance criteria specified in ISO 3310-1:2016 and ASTM E11–22 for test sieve shakers.
Can the digital timer store multiple preset durations?

No—the SS-14D/DF timer retains only the most recently programmed duration and settings in non-volatile memory; it does not support multi-profile storage.
What is the maximum recommended load per sieve stack?

For optimal separation efficiency and motor longevity, Gilson recommends ≤ 150 g per 8-inch sieve and ≤ 300 g per 12-inch sieve when processing materials within the No. 4–No. 200 range.
Does the EZ-Clamp™ system require tools for adjustment?

No—all clamping operations are tool-free; the integrated lever and twist-lock mechanism enables secure stack assembly and disassembly in under 10 seconds per setup.
