Overview
The W.S. Tyler 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 employs a dual-motion mechanism—horizontal circular oscillation combined with vertical tapping—to replicate the manual sieving action defined in regulatory test methods. This synchronized motion ensures uniform energy transfer across the entire sieve stack, minimizing segregation bias and maximizing reproducibility in dry granular material classification. The SS-30 is specifically configured for high-throughput laboratories requiring consistent, traceable, and auditable sieve analysis results under GLP or GMP environments. Its robust cast-iron frame, permanently lubricated 1/4 HP induction motor, and vibration-dampening base design support continuous operation without performance drift or mechanical fatigue.
Key Features
- Dual-motion kinematics: 278 oscillations per minute + 150 taps per minute—precisely calibrated to meet ASTM D1193 and ISO 2591-1 timing requirements
- Integrated digital timer with 0.1-second resolution and programmable duration up to 99 minutes, supporting repeatable method execution and audit-ready timestamping
- Quick-adjust sieve support plate accommodates full-height (203 mm), half-height, or ISO-standard 200 mm diameter sieves without tools
- Stable mounting interface enables secure bolt-down installation to laboratory benches or isolation tables, reducing ambient vibration transmission
- Thermally protected motor with sealed bearings and IP54-rated enclosure for long-term reliability in dusty QC/QA environments
- Compatibility with W.S. Tyler’s full range of ASTM-certified woven-wire and perforated test sieves, including stainless steel, brass, and nickel alloys
Sample Compatibility & Compliance
The SS-30 accommodates up to six full-height 8-inch (203 mm) test sieves stacked vertically—or thirteen half-height sieves—in a single run. It supports particle size separations from No. 4 (4.75 mm) down to No. 635 (20 µm) per ASTM E11 grading standards. All operational parameters—including tap amplitude, oscillation radius, and dwell time—are factory-set and mechanically locked to ensure inter-laboratory comparability. The unit complies with electrical safety standards IEC 61000-6-3 (EMC) and UL 61010-1, and its mechanical design conforms to ISO 2591-1:2022 for sieve shaker performance validation. When operated with ASTM-certified sieves and documented SOPs, data generated on the SS-30 satisfies FDA 21 CFR Part 11 requirements for electronic records when paired with compliant LIMS or ELN systems.
Software & Data Management
While the SS-30 operates as a standalone electromechanical instrument, its deterministic motion profile and precise timer enable seamless integration into regulated workflows. Digital timer logs (via external USB data logger or optional RS-232 interface add-on) provide time-stamped start/stop events for audit trails. When used within validated analytical procedures, the SS-30 supports ALCOA+ data integrity principles—ensuring data is Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, and Available. Optional accessories—including sound-dampening enclosures (W.S. Tyler SoundShell®) and Clean-N-STOR fraction collectors—extend functionality while maintaining compliance with ISO 17025 clause 6.4.3 on equipment suitability.
Applications
- Pharmaceutical granulation and excipient characterization per USP <786> and EP 2.9.32
- Metal powder quality control in additive manufacturing feedstock qualification (ASTM F3049)
- Aggregates and cement fineness testing per ASTM C136 and EN 10106
- Food ingredient particle distribution analysis (e.g., flour, sugar, spices) under FDA Food Safety Modernization Act (FSMA) protocols
- Geotechnical soil gradation per ASTM D6913 and AASHTO T 27
- Chemical catalyst and pigment dispersion screening in R&D and production QC labs
FAQ
What voltage configurations are available for the SS-30 model?
The SS-30 is supplied in three standard variants: SS-30 (115 V / 60 Hz), SS-30F (230 V / 50 Hz), and SS-30S (230 V / 60 Hz), each rated at 1/4 HP and thermally protected.
Can the SS-30 accommodate ISO 200 mm sieves?
Yes—the SS-30’s adjustable sieve support plate accepts both 8-inch (203 mm) ASTM sieves and ISO 200 mm diameter test sieves without modification.
Is the SS-30 suitable for GMP-regulated environments?
Yes—when operated with documented SOPs, calibrated sieves, and integrated into a validated process, the SS-30 meets the mechanical reliability and traceability criteria outlined in EU Annex 15 and FDA Guidance for Industry on Analytical Procedures.
What is the maximum sieve stack height supported by the SS-30?
The SS-30 supports up to six full-height 8-inch sieves (including pan) or thirteen half-height sieves in a single run, with total stack height limited to 305 mm (12 inches) for mechanical stability.
Does the SS-30 require periodic recalibration?
No—its motion parameters are mechanically fixed and do not drift over time. However, annual verification against ASTM E11 Annex A3 motion calibration procedures is recommended for ISO/IEC 17025 accreditation.
