Overview
The W.S. Tyler Ro-Tap® SS30S 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 classic Ro-Tap® motion profile—combining horizontal circular oscillation (278 cycles/min) with vertical tapping (150 taps/min)—to ensure uniform particle stratification, efficient sieve loading, and high reproducibility across repeated analyses. Unlike orbital or vibratory shakers, the Ro-Tap® mechanism delivers deterministic, kinematically defined motion that minimizes particle agglomeration and screen blinding, making it the benchmark for dry-sieving applications in QC laboratories, mineral processing, pharmaceuticals, and construction materials testing. The SS30S variant is specifically configured for 230V / 60Hz operation, complying with North American and select international industrial power standards while maintaining full compatibility with legacy Ro-Tap® accessories and calibration protocols.
Key Features
- True Ro-Tap® dual-motion mechanism: 278 oscillations/min + 150 vertical taps/min, traceable to ASTM E11 Annex A1 requirements
- Dual-voltage compatibility via model-specific motor winding: SS30S supports stable 230V / 60Hz input at 2.2A (0.25 HP continuous-duty induction motor)
- Integrated digital timer with 0.1-second resolution and programmable range up to 99 minutes—supports GLP-compliant test logging when paired with external audit-trail software
- Quick-adjust sieve support plate accommodates up to six full-height 8-inch (203 mm) test sieves or thirteen half-height sieves in a single stack configuration
- Robust cast-iron base and reinforced steel frame engineered for long-term stability under continuous operation; includes pre-drilled mounting holes for bench bolting
- Full compatibility with ASTM E11-compliant wire cloth sieves (No. 4–No. 635; 4.75 mm–20 µm), ISO 3310-1 standard sieves (200 mm diameter), and W.S. Tyler’s proprietary Clean-N-STOR fraction collection system
Sample Compatibility & Compliance
The SS30S is validated for dry, free-flowing granular samples ranging from coarse aggregates (½ inch / 12.5 mm) down to fine powders (20 µm). It is routinely employed in ASTM C136 (coarse/fine aggregate gradation), ASTM D6913 (soil particle-size analysis), and USP <786> (pharmaceutical granule sizing). All mechanical motion parameters are factory-calibrated and documented per ISO/IEC 17025 traceable procedures. The unit meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and safety (EN 61000-3-2), and its structural design conforms to OSHA-recommended vibration isolation guidelines when mounted on rigid surfaces. Optional sound enclosure (W.S. Tyler Sound Shell®) reduces operational noise to ≤72 dBA at 1 m distance.
Software & Data Management
While the SS30S operates as a standalone electromechanical instrument without embedded firmware, its timer output can be interfaced with external data acquisition systems via TTL-compatible relay signals (optional accessory). When integrated into regulated environments (e.g., FDA-regulated pharmaceutical labs), users commonly pair the shaker with LIMS platforms or electronic lab notebooks (ELNs) that support 21 CFR Part 11-compliant audit trails. W.S. Tyler provides full documentation packages—including Factory Acceptance Test (FAT) reports, calibration certificates, and maintenance logs—for GMP/GLP validation readiness. Firmware-free architecture ensures long-term reliability and eliminates cybersecurity vulnerabilities associated with connected instruments.
Applications
- Quality control of cement, fly ash, and mineral fillers per ASTM C91, C618, and EN 197-1
- Particle size distribution analysis of API excipients and granules in solid-dose manufacturing
- Aggregate gradation testing for asphalt and concrete mix design (ASTM C136, AASHTO T 27)
- Soil classification and sediment analysis in geotechnical and environmental laboratories
- Routine sieve calibration verification using certified reference materials (CRMs) traceable to NIST SRM 2000 series
- Research-scale powder flow characterization where mechanical energy input must remain constant across replicates
FAQ
What sieve diameters and configurations does the SS30S support?
The SS30S accepts 8-inch (203 mm) test sieves exclusively—either six full-height sieves with full-height pan or thirteen half-height sieves with half-height pan. ISO 200 mm sieves are mechanically compatible but require adapter rings (sold separately).
Is the SS30S suitable for wet sieving?
No. The SS30S is strictly a dry-sieving instrument. Wet sieving requires pressurized liquid delivery systems and corrosion-resistant construction not present in Ro-Tap® models.
Can the SS30S be validated for 21 CFR Part 11 compliance?
Yes—though the shaker itself has no electronic data storage, its timer relay output enables integration with compliant LIMS or ELN systems that enforce electronic signatures, audit trails, and access controls.
What maintenance is required for long-term accuracy?
Annual verification of tap amplitude (±0.5 mm tolerance) and oscillation frequency (±2 rpm) using calibrated laser tachometry is recommended. Motor lubrication is sealed-for-life; only external cleaning and bolt-torque verification are routine user tasks.
Does the SS30S include test sieves or collection accessories?
No. Sieves, pans, and accessories such as Clean-N-STOR fraction collectors or Sound Shell® enclosures are ordered separately to match application-specific requirements.
