Overview
The Gilson SS-30 Ro-Tap® Sieve Shaker is a precision-engineered mechanical sieve shaker designed to perform standardized particle size distribution analysis in accordance with ASTM E11, ISO 3310-1, and USP <786>. It replicates the dual-motion protocol defined in ASTM D4782 and D6913: a controlled horizontal circular oscillation (278 cycles/min) combined with vertical tapping (150 taps/min). This synchronized motion ensures uniform particle agitation across the full active screening area, minimizing segregation and maximizing sieving efficiency—particularly for dry, free-flowing granular materials ranging from coarse aggregates to fine powders. Built around W.S. Tyler’s legacy Ro-Tap® platform and distributed exclusively by Gilson in North America, the SS-30 integrates a robust 1/4 HP induction motor, rigid cast-iron frame, and vibration-dampening base mount capability for stable operation under high-duty laboratory or QC environments.
Key Features
- ASTM-compliant dual-motion mechanism: 278 oscillations/min + 150 vertical taps/min for reproducible, method-validated results
- Supports up to six full-height 8-inch (203 mm) test sieves—or thirteen half-height sieves—in a single stack configuration
- Digital timer with 0.1-second resolution and 99-minute maximum duration, enabling precise, repeatable test execution
- Quick-adjust sieve clamp system with positive-locking tension control for rapid setup and consistent sieve compression
- Compatibility with both ASTM-standard (inch-based) and ISO-standard (metric) 200 mm diameter sieves
- Optional mounting hardware for benchtop anchoring to suppress resonance and enhance measurement stability
- Thermally protected motor with continuous-duty rating and low-maintenance brushless design
Sample Compatibility & Compliance
The SS-30 is validated for use with dry, non-cohesive, and moderately cohesive particulate samples—including soils, pharmaceutical excipients, catalysts, metal powders, and mineral aggregates. It accommodates particle size ranges from No. 4 (4.75 mm) to No. 635 (20 µm) per ASTM E11 specifications. All mechanical and timing parameters meet the repeatability requirements of ISO/IEC 17025-accredited testing laboratories. The unit conforms to UL 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and CE marking directives for electromagnetic compatibility (EMC) and low-voltage operation. When operated within documented SOPs and paired with NIST-traceable calibration sieves, data generated on the SS-30 satisfies FDA 21 CFR Part 11 expectations for audit-ready particle sizing records.
Software & Data Management
While the SS-30 operates as a standalone electromechanical instrument without embedded software, its deterministic timing architecture and analog motor control ensure full traceability and method fidelity—critical for GLP/GMP-regulated environments. Users integrate the shaker into broader LIMS or ELN workflows via manual entry of run parameters (duration, sieve stack configuration, sample ID) and post-sieving mass measurements. Optional accessories—including Gilson’s Clean-N-STOR fraction collector and digital balance interfaces—enable semi-automated data capture and reduce transcription error. For laboratories requiring electronic record integrity, the SS-30 supports integration with third-party time-stamped logging systems that record start/stop events, voltage input stability, and operator ID via external PLC or USB-triggered data loggers compliant with 21 CFR Part 11 Annex 11 principles.
Applications
- Quality control of raw materials and finished products in pharmaceutical manufacturing (e.g., API particle size qualification per USP <786>)
- Soil gradation analysis per ASTM D6913 for geotechnical engineering and ASTM D4782 for aggregate classification
- Characterization of ceramic powders, battery electrode materials, and additive manufacturing feedstocks
- Validation of milling and micronization process endpoints in R&D and production settings
- Compliance testing for ISO 13320 laser diffraction correlation studies, where sieve analysis serves as orthogonal reference method
- Teaching laboratories performing hands-on instruction in particle technology and powder characterization fundamentals
FAQ
What voltage configurations are available for the SS-30 model?
The SS-30 is supplied in three electrical variants: SS-30 (115 V / 60 Hz), SS-30F (230 V / 50 Hz), and SS-30S (230 V / 60 Hz). Each variant maintains identical mechanical performance and timing accuracy.
Can ISO 200 mm sieves be used interchangeably with ASTM 8-inch frames?
Yes—the SS-30’s universal sieve holder accepts both 203 mm (8-inch) ASTM frames and 200 mm ISO frames without adapter kits. Tolerance alignment ensures minimal edge gap and optimal energy transfer during tapping.
Is the SS-30 suitable for wet sieving applications?
No. The SS-30 is strictly configured for dry-sieving protocols. For wet analysis, Gilson recommends the SS-30W-compatible ultrasonic dispersion module or dedicated wet-sieve shakers such as the SS-31W series.
How does the SS-30 differ from the SS-33 Ro-Tap® II model?
The SS-33 features dual independent 8-inch sieve stacks operating simultaneously under identical motion profiles, enabling parallel testing or comparative analysis. The SS-30 is a single-stack unit optimized for throughput and footprint efficiency.
Does Gilson provide calibration documentation or verification services?
Gilson supplies factory-verified timing certificates (±0.5% tolerance on tap/oscillation frequency) with each unit. On-site calibration and IQ/OQ validation support are available through Gilson’s Certified Service Network under GxP-compliant service agreements.
