Overview
The W.S. Tyler SS30S Ro-Tap® Sieve Shaker is a precision-engineered mechanical sieving instrument designed to perform standardized dry particle size analysis in accordance with ASTM E11, ISO 3310-1, and USP <786>. It replicates the manual sieving motion defined by ASTM D6913 and D422—combining horizontal circular oscillation (278 cycles/min) with vertical tapping (150 taps/min)—to ensure reproducible, operator-independent separation of granular and powdered materials. Unlike rotary or vibratory shakers, the Ro-Tap® mechanism delivers true two-dimensional motion that promotes stratification, particle reorientation, and efficient passage through sieve apertures. The SS30S variant is configured for 230 V / 60 Hz operation and supports up to six full-height 8-inch (203 mm) test sieves or thirteen half-height sieves in a single run, making it ideal for QC laboratories, aggregate testing facilities, pharmaceutical development labs, and R&D environments requiring strict adherence to regulatory sieving protocols.
Key Features
- ASTM-compliant dual-motion drive: 278 oscillations/min + 150 taps/min for high-fidelity simulation of manual sieving
- Digital timer with 0.1-second resolution and 99-minute maximum duration for precise, repeatable test execution
- Robust 1/4 HP induction motor engineered for continuous-duty operation and long-term mechanical stability
- Quick-adjust sieve support plate accommodates full-height, half-height, and intermediate-height sieve stacks without tools
- Universal compatibility with both ASTM-standard 8-inch (203 mm) sieves and ISO 200 mm diameter sieves
- Heavy-gauge steel frame with bolt-down mounting capability for vibration isolation and operational safety
- Optional accessories include sound-dampening enclosures (W.S. Tyler SoundShell®), Clean-N-STOR fraction collectors, and calibrated test sieves per ISO 3310-1
Sample Compatibility & Compliance
The SS30S is validated for use across a broad range of dry, free-flowing, non-cohesive particulates—including mineral aggregates, metal powders, catalysts, APIs, excipients, ceramics, and food-grade ingredients. It supports particle size separations from No. 4 (4.75 mm) down to No. 635 (20 µm) using standard W.S. Tyler test sieves. All mechanical motion parameters meet the repeatability requirements of ASTM E323 and ISO 2591-1. When operated with traceable, NIST-traceable certified sieves and documented SOPs, the system supports GLP and GMP workflows. Data integrity is reinforced via audit-ready timing logs and manual calibration records—fully compatible with FDA 21 CFR Part 11–aligned documentation practices when integrated into validated laboratory information management systems (LIMS).
Software & Data Management
The SS30S operates as a standalone electromechanical instrument with no embedded firmware or proprietary software. Its digital timer provides timestamped start/stop events and elapsed time logging, which can be manually recorded or interfaced with external data acquisition systems via optional relay outputs (available on select configurations). For laboratories implementing electronic records, the device supports integration into validated LIMS or ELN platforms through procedural documentation—ensuring alignment with ISO/IEC 17025 clause 7.7 (result reporting) and USP <1058> analytical instrument qualification (AIQ) requirements. Calibration certificates for timing accuracy and motor speed are issued annually per manufacturer-recommended maintenance schedules.
Applications
- Quality control of bulk pharmaceutical powders per USP <786> and EP 2.9.36
- Aggregate gradation analysis in civil engineering per ASTM C136 and AASHTO T 27
- Particle size distribution (PSD) verification of metal injection molding (MIM) feedstocks
- API crystallization endpoint monitoring and polymorph screening
- Soil and sediment classification per ASTM D422 and D6913
- Validation of milling and micronization processes in chemical manufacturing
- Research-grade PSD profiling for battery cathode/anode materials and catalyst supports
FAQ
What voltage and frequency does the SS30S operate at?
The SS30S is rated for 230 V AC, 60 Hz operation with a nominal current draw of 2.2 A.
Can ISO 200 mm sieves be used on the SS30S?
Yes—the SS30S accepts both ASTM-standard 8-inch (203 mm) and ISO 200 mm diameter test sieves using compatible adapter rings.
What is the maximum number of sieves supported in a single run?
Six full-height 8-inch sieves (with full-height pan) or thirteen half-height 8-inch sieves (with half-height pan).
Is the SS30S compliant with FDA 21 CFR Part 11?
As a Class I electromechanical device without electronic data storage or user authentication, the SS30S itself is not subject to Part 11—but its output supports Part 11–compliant workflows when paired with validated procedural controls and external record-keeping systems.
Does the unit require periodic calibration?
Yes—annual verification of timer accuracy (±0.1 sec), tap/oscillation frequency (via tachometer), and mechanical alignment is recommended per W.S. Tyler Service Bulletin SB-RT-002.
