Overview
The Gilson SS-30 Ro-Tap® Mechanical Sieve Shaker is a precision-engineered laboratory instrument designed for standardized dry sieve 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 and high reproducibility across granular and powdered samples. This dual-motion mechanism promotes efficient particle passage through stacked test sieves while minimizing blinding and agglomeration effects. Built for sustained operation in QC laboratories, R&D facilities, and contract testing environments, the SS-30 features a robust cast-iron frame, vibration-dampening feet, and optional bench-mounting capability to enhance mechanical stability during extended runs. Its ¼ HP induction motor delivers consistent torque under load, supporting rigorous compliance with GLP and GMP documentation requirements when integrated with validated digital timers.
Key Features
- Ro-Tap®-certified motion profile: 278 oscillations/min + 150 vertical taps/min per ASTM D6913 and ISO 2591-1
- Dual-voltage compatibility: Configurable models available for 115V/60Hz (SS-30), 230V/50Hz (SS-30F), and 230V/60Hz (SS-30S) operation
- High-capacity sieve stack: Accommodates up to six full-height 8-inch (203 mm) test sieves or thirteen half-height sieves using the standard pan assembly
- Precision digital timer: 0.1-second resolution with programmable range up to 99 minutes, supporting repeatable method execution and audit-ready logging
- Quick-adjust sieve support plate: Tool-free height calibration ensures optimal contact pressure between adjacent sieves and maintains consistent energy transfer
- Universal sieve compatibility: Accepts both ASTM-standard 8-inch diameter sieves and ISO 200 mm round sieves with interchangeable clamping hardware
- Low-noise operational design: Optional W.S. Tyler Sound Enclosure (sold separately) reduces ambient noise by >25 dB(A) for shared lab environments
Sample Compatibility & Compliance
The SS-30 is validated for particle size distribution analysis of free-flowing, non-cohesive materials including aggregates, pharmaceutical powders, catalysts, metal powders, ceramics, and soil fractions. It supports nominal sieve openings from No. 4 (4.75 mm) to No. 635 (20 µm), making it suitable for coarse-to-fine gradation testing in civil engineering, mineral processing, and formulation development. All Ro-Tap® shakers comply with mechanical performance criteria defined in ASTM E323 and ISO/IEC 17025-accredited calibration protocols. When used with certified reference sieves traceable to NIST standards, the system meets FDA 21 CFR Part 11 requirements for electronic records when paired with compliant data acquisition software.
Software & Data Management
While the SS-30 operates as a standalone electromechanical unit, its timer output can be interfaced with external data loggers or LIMS via TTL pulse signaling (optional accessory). Gilson’s GilsonLog™ software suite (v5.2+) supports automated method recall, run history archiving, and PDF report generation—including sieve stack configuration, timing parameters, and operator ID—for full traceability. Audit trails record timestamped start/stop events, timer resets, and parameter changes—enabling compliance with ISO 9001, ISO 13485, and pharmaceutical validation protocols (IQ/OQ/PQ). Firmware updates are delivered via USB and maintain backward compatibility with legacy calibration certificates.
Applications
- Aggregate gradation testing per ASTM C136/C136M in concrete and asphalt QA/QC
- Pharmaceutical powder flow characterization per USP <786> and EP 2.9.32
- Catalyst and battery electrode material sizing in R&D labs
- Quality control of abrasive media, foundry sands, and ceramic raw materials
- Soil particle-size analysis per ASTM D422 and AASHTO T 88
- Validation of milling and micronization processes in fine chemical manufacturing
FAQ
What sieve diameters and heights does the SS-30 support?
The SS-30 accepts full-height, half-height, and intermediate-height 8-inch (203 mm) test sieves. ISO 200 mm sieves are also compatible with adapter plates.
Can the SS-30 be mounted to a lab bench?
Yes—the unit includes pre-drilled mounting holes and rubber isolation feet; anchoring to a rigid surface improves repeatability during high-cycle testing.
Is the timer output compatible with LIMS integration?
The digital timer provides TTL-compatible pulse outputs for external logging; full LIMS integration requires GilsonLog™ or third-party middleware with Modbus RTU support.
Does Gilson provide calibration services for the SS-30?
Yes—Gilson offers factory-certified calibration (NIST-traceable motion verification) and on-site IQ/OQ protocol execution per client SOP requirements.
How does the SS-30 differ from the SS-31 and SS-33 models?
The SS-31 supports larger 12-inch sieves and broader coarse-range applications; the SS-33 enables parallel dual-stack testing for throughput optimization—both share identical motion dynamics and timer architecture.
