Overview
The Gilson SS-15DF is a precision-engineered, benchtop mechanical sieve shaker designed for standardized particle size distribution analysis in accordance with ASTM E11, ISO 3310-1, and USP <786> requirements. It employs a dual-motion orbital shaking mechanism—combining horizontal reciprocation with controlled vertical inclination—to replicate the reproducible, operator-independent motion of manual sieving while eliminating human variability. This principle ensures uniform particle stratification and efficient separation across the full analytical range (4.75 mm to 75 µm), critical for quality control in aggregate testing, pharmaceutical granulation studies, mineral processing, and feed formulation laboratories.
Key Features
- Integrated digital countdown timer with ±1-second accuracy up to 99 minutes, featuring large 0.5-inch (12.7 mm) high-brightness LED display for clear visibility under laboratory lighting conditions
- EZ-Clamp™ quick-release system: single-action sliding rod with push-button engagement and locking rotary knob—enables secure, tool-free assembly of stacked sieve columns in under 10 seconds
- Robust 1/4 HP sealed motor delivering consistent amplitude and frequency stability over extended operational cycles
- Modular stack configuration supports either six full-height 8-inch (203 mm) sieves + receiver pan or twelve half-height 8-inch sieves + pan—fully compatible with both ASTM and ISO 200 mm standard sieve frames
- Pause/resume functionality preserves elapsed time during interruption, ensuring compliance with test method procedural continuity requirements
- Acoustic end-of-cycle alert (5-second audible tone) synchronized with visual timer completion signal
- Stable free-standing chassis with non-slip rubber feet; optional mounting brackets available for permanent installation on vibration-dampened workbenches
Sample Compatibility & Compliance
The SS-15DF accommodates a broad spectrum of sieve materials and configurations—including brass, stainless steel, copper-frame stainless mesh, polyester, nylon, and nickel alloy wet-sieving screens—enabling method flexibility across dry and wet sieving protocols. All sieve frame dimensions conform to NIST-traceable dimensional tolerances per ASTM E11-09. The shaker’s mechanical performance is validated against ISO 2591-1 for reproducibility (RSD ≤ 3.5% for repeated analyses of certified reference aggregates) and meets GLP documentation prerequisites when paired with audit-trail-enabled data logging software. It supports regulatory submissions requiring adherence to FDA 21 CFR Part 11-compliant electronic records when integrated with validated LIMS interfaces.
Software & Data Management
While the SS-15DF operates as a standalone instrument, its timer logic and cycle parameters are fully compatible with Gilson’s optional SieveLink™ PC interface module (sold separately). This enables automated test logging—including timestamped start/stop events, user ID tagging, sieve stack configuration metadata, and pass/fail status flags—exportable in CSV or XML formats for integration into enterprise quality management systems (QMS). Audit trails comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), satisfying GMP and ISO/IEC 17025 documentation mandates.
Applications
- Aggregate gradation testing per ASTM C136/C136M and AASHTO T 27 for concrete, asphalt, and base course materials
- Pharmaceutical powder characterization per USP <786> and EP 2.9.31 for blend uniformity and dissolution rate prediction
- Mineral ore liberation analysis in metallurgical process development
- Feed and grain particle size profiling for digestibility optimization and pelleting efficiency assessment
- Catalyst support particle sizing in chemical manufacturing QA/QC workflows
- Recycled construction material classification per EN 933-1 and BS EN 933-2
FAQ
Does the SS-15DF include sieve trays?
No—the SS-15DF is supplied as a base unit only. Sieve frames (ASTM or ISO 200 mm), receivers, and calibration standards must be selected separately based on application-specific requirements.
Can the SS-15DF accommodate non-standard sieve diameters?
Yes—adapters are available for 3-inch, 6-inch, 10-inch, 12-inch, and 18-inch sieve frames; ISO 300 mm compatibility requires optional mounting kit SSA-806.
Is the EZ-Clamp™ system backward-compatible with legacy Gilson shakers?
Yes—the SSA-806 SS-15 EZ Clamp Upgrade Kit allows retrofitting of older SS-15 and SS-15D units with current-generation clamping hardware.
What power supply specifications does the SS-15DF require?
The unit operates on 220 V AC, 50 Hz single-phase input with internal thermal overload protection and meets IEC 61000-6-3 EMC emission standards.
How is calibration verification performed?
Gilson recommends annual verification using NIST-traceable vibration amplitude calibrators (e.g., PCB Piezotronics Model 356B18) and documented traceability to ISO/IEC 17025-accredited labs. Factory calibration certificates are available upon request.
