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 classic Ro-Tap® motion profile—combining horizontal circular oscillation (278 cycles/min) with vertical tapping (150 taps/min)—to ensure uniform particle stratification and efficient separation across stacked test sieves. This dual-motion mechanism minimizes particle agglomeration and promotes consistent, repeatable sieving performance essential for quality control laboratories, geological testing facilities, pharmaceutical R&D, and materials science applications. Built around a robust 1/4 HP induction motor and rigid cast-iron frame, the SS-30 delivers long-term operational stability under high-frequency duty cycles. Its compact footprint and optional bench-mounting capability make it suitable for both standalone use and integration into controlled-environment testing suites.
Key Features
- Ro-Tap®-certified dual-motion drive system: 278 oscillations/min + 150 vertical taps/min for ASTM-compliant sieving
- Digital timer with 0.1-second resolution and programmable range up to 99 minutes
- Quick-adjust sieve support plate accommodates full-height (203 mm), half-height, or intermediate-height sieves without tools
- Compatible with standard 8-inch (203 mm) diameter ASTM E11 and ISO 3310-1 test sieves—including stainless steel, brass, and nylon mesh configurations
- Supports up to six full-height 8-inch sieves in a single stack, or thirteen half-height sieves using optional half-height pan assemblies
- Integrated vibration-dampening base design; compatible with W.S. Tyler Sound Enclosure for noise reduction in shared lab environments
- UL-listed electrical system rated for 115 V / 60 Hz / 4.4 A operation; CE-compliant variants available (SS-30F, SS-30S)
Sample Compatibility & Compliance
The SS-30 is validated for dry-sieving applications across a broad particle size range—from No. 4 (4.75 mm) down to No. 635 (20 µm) mesh—making it ideal for aggregates, powders, catalysts, APIs, excipients, ceramics, and mineral ores. Its mechanical architecture meets the dimensional and kinetic requirements specified in ASTM D6913, D1140, C136, and ISO 13320 Annex B for sieve analysis instrumentation. When operated with traceable calibration sieves and documented SOPs, the system supports GLP and GMP audit readiness. Data integrity is reinforced through non-volatile timer memory and physical lockout of timing parameters during active runs—aligning with FDA 21 CFR Part 11 principles for electronic records where integrated software interfaces are deployed.
Software & Data Management
While the SS-30 operates as a standalone electromechanical instrument, its timing protocol and motion fidelity enable seamless integration into LIMS and ELN workflows via external data capture modules (e.g., USB-timed relay triggers or RS-232–enabled timers). Gilson’s optional DataLink™ interface allows synchronization with Gilson AutoSieve™ software for automated run logging, pass/fail threshold validation against specification limits, and PDF report generation compliant with ISO/IEC 17025 documentation standards. All firmware updates and configuration backups are performed via secure USB port, preserving audit trails for regulatory review.
Applications
- Aggregate gradation testing per ASTM C136 and AASHTO T 27 in civil engineering labs
- Pharmaceutical powder characterization per USP <786> and EP 2.9.31 for content uniformity and dissolution prediction
- Quality assurance of metal powders used in additive manufacturing (ASTM F3049)
- Soil particle-size analysis per ASTM D6913 for geotechnical classification
- Ceramic raw material screening prior to sintering or slip casting
- Recycled construction material sorting and contamination assessment
FAQ
What sieve diameters and heights does the SS-30 support?
The SS-30 is configured exclusively for 8-inch (203 mm) diameter test sieves and accommodates full-height, half-height, and intermediate-height configurations using interchangeable support plates.
Is the SS-30 compliant with ISO 3310-1?
Yes—the motion profile, amplitude, and timing accuracy meet ISO 3310-1 Clause 6.2 requirements for mechanical sieve shakers when used with certified ISO-standard sieves.
Can the SS-30 be mounted to a laboratory bench?
Yes—four pre-drilled mounting holes (¼”-20 UNC) are provided on the base plate for secure bolt-down installation to minimize vibration transmission.
Does the SS-30 include test sieves?
No—test sieves must be selected separately based on application requirements; Gilson offers ASTM E11 and ISO 3310-1–certified sieves in stainless steel, brass, and nylon mesh with nominal openings from 20 µm to 12.5 mm.
What is the expected service life under routine QC use?
With scheduled maintenance (lubrication every 500 operating hours and annual motor inspection), the SS-30 maintains metrological reliability for ≥10 years at typical lab throughput (≤8 runs/day).
