Overview
The Gilson SS30S Ro-Tap® Sieve Shaker is a precision-engineered mechanical sieve shaker designed to perform standardized dry particle size analysis in accordance with ASTM E11, ISO 3310-1, and USP <786>. It replicates the classic Ro-Tap® motion—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 profile minimizes particle agglomeration and screen blinding while maximizing reproducibility across repeated analyses. Built for high-throughput laboratory and quality control environments, the SS30S features a robust 1/4 HP induction motor, rigid cast-iron frame, and vibration-dampening base mount compatibility. Its 230V / 60Hz electrical configuration meets international voltage standards for laboratories operating under North American or compatible grid specifications, offering stable performance without frequency conversion requirements.
Key Features
- Ro-Tap® patented dual-motion mechanism: 278 oscillations/min + 150 vertical taps/min per ASTM E11 and ISO 3310-1 protocols
- Digital electronic timer with 0.1-second resolution and programmable duration up to 99 minutes
- Quick-adjust sieve support plate accommodates full-height (203 mm), half-height, or ISO 200 mm diameter sieves
- Supports up to six full-height 8-inch (203 mm) test sieves or thirteen half-height sieves in a single stack
- Heavy-duty cast-iron housing with reinforced mounting points for benchtop bolting to minimize operational displacement
- Thermally protected 1/4 HP AC induction motor delivering consistent torque across extended duty cycles
- Compliance-ready design: supports audit trails when integrated with validated LIMS or ELN systems under FDA 21 CFR Part 11 guidelines
Sample Compatibility & Compliance
The SS30S is validated for use with standard W.S. Tyler® Ro-Tap® test sieves—including ASTM E11-compliant brass, stainless steel, and nylon-mesh frames—as well as ISO 3310-1 certified 200 mm diameter sieves. It delivers reliable separation across particle size ranges from No. 4 (4.75 mm) to No. 635 (20 µm), making it suitable for applications in pharmaceutical granulation, mineral processing, catalyst characterization, and powdered food ingredient QC. All motion parameters are traceable to NIST-traceable calibration references. The unit conforms to IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity), and its mechanical construction satisfies CE marking requirements for machinery safety (2006/42/EC). When operated within a Gilson Sound Enclosure (sold separately), noise emission is reduced to ≤65 dBA at 1 m—supporting ISO 140-4 acoustic compliance in shared lab spaces.
Software & Data Management
While the SS30S operates as a standalone electromechanical instrument without embedded firmware or network connectivity, its digital timer output can be interfaced via optional analog signal modules (e.g., 0–10 V or 4–20 mA) for integration into centralized process monitoring systems. For GLP/GMP environments, users may document run parameters—including voltage, runtime, sieve stack configuration, and operator ID—in structured electronic batch records. The device supports 21 CFR Part 11-compliant data integrity practices when paired with validated third-party software platforms that enforce electronic signatures, audit trails, and change control for analytical method execution logs. Calibration certificates and maintenance records are maintained per ISO/IEC 17025:2017 clause 6.4.10.
Applications
- Pharmaceutical solid dosage form development: excipient and API particle size distribution profiling per USP <786>
- Geotechnical soil gradation analysis per ASTM D6913 and AASHTO T 27
- Cement and clinker fineness testing per ASTM C114 and EN 196-6
- Food powder flowability assessment via sieve residue analysis (e.g., flour, sugar, dairy powders)
- Recycled aggregate classification in construction materials QA/QC programs
- Research-grade particulate behavior studies requiring high inter-laboratory reproducibility
FAQ
What voltage and frequency configurations does the SS30S support?
The SS30S is configured for 230V / 60Hz operation with a rated current draw of 2.2A. It is not compatible with 50Hz or 115V supply without external transformer or frequency converter.
Can the SS30S accommodate ISO 200 mm test sieves?
Yes—the adjustable sieve support plate is engineered to accept both 8-inch (203 mm) ASTM-standard sieves and ISO 3310-1 compliant 200 mm diameter sieves without adapter hardware.
Is the SS30S suitable for GMP-regulated environments?
Yes, provided it is included in a validated equipment qualification protocol (IQ/OQ/PQ) and operated with documented procedures, calibrated sieves, and traceable timing records aligned with FDA 21 CFR Part 11 expectations.
What is the maximum number of sieves supported in a single stack?
Six full-height 8-inch (203 mm) test sieves with full-height pan, or thirteen half-height sieves with half-height pan.
Does the unit include a sound enclosure?
No—the Gilson Sound Enclosure (Model SE-RO-TAP) is an optional accessory sold separately to reduce operational noise to laboratory-safe levels.
