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 dual-motion protocol defined in ASTM D6913 and D422—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 synchronized motion mimics manual sieving while eliminating operator variability, delivering high reproducibility for QC laboratories, aggregate testing facilities, pharmaceutical development labs, and R&D centers requiring regulatory-compliant granulometric data.
Key Features
- ASTM- and ISO-compliant dual-motion mechanism: 278 oscillations per minute + 150 vertical taps per minute, precisely calibrated to meet method requirements for sieve analysis.
- Dedicated 8-inch (203 mm) platform supporting up to six full-height test sieves or thirteen half-height sieves in a single run—optimized for throughput without compromising accuracy.
- Robust 1/4 HP induction motor with thermal overload protection ensures stable, long-term operation under continuous use conditions.
- Integrated digital timer with 0.1-second resolution and 99-minute maximum duration enables precise, repeatable test cycle control—critical for GLP/GMP environments.
- Quick-adjust sieve support plate allows rapid reconfiguration between full-, half-, and intermediate-height sieve stacks without tools.
- Universal compatibility with W.S. Tyler® Ro-Tap®-certified ASTM E11 and ISO 3310-1 test sieves (including 200 mm diameter ISO formats).
- Heavy-duty steel frame with bolt-down mounting capability minimizes vibration transmission and enhances measurement stability on laboratory benches.
Sample Compatibility & Compliance
The SS-30 accommodates dry, free-flowing granular materials across a broad particle size range—from No. 4 (4.75 mm) down to No. 635 (20 µm)—making it suitable for soils, aggregates, catalysts, metal powders, APIs, excipients, and ceramic raw materials. Its mechanical design and motion profile are validated for conformance with ASTM D6913 (Soil Particle-Size Analysis), ASTM C136 (Aggregate Sieve Analysis), ISO 13320 (Laser Diffraction—used as reference correlation tool), and USP <786> (Particle Size Distribution of Pharmaceutical Powders). The unit supports audit-ready workflows when paired with compliant documentation practices and electronic records systems adhering to FDA 21 CFR Part 11 principles.
Software & Data Management
While the SS-30 operates as a standalone electromechanical instrument without embedded software, its deterministic timing and repeatable motion profile integrate seamlessly into LIMS and ELN platforms via external data capture protocols. Users may log sieve stack configurations, timer settings, and weight measurements manually or through barcode-scanned sieve ID tracking. For laboratories implementing digital quality systems, the SS-30’s consistent performance serves as a reliable physical layer in automated particle characterization workflows—especially when combined with Gilson’s complementary gravimetric balance interfaces and SOP-driven reporting templates aligned with ISO/IEC 17025 calibration management requirements.
Applications
- Quality control of bulk pharmaceutical powders per USP <786> and EP 2.9.32.
- Gradation testing of coarse and fine aggregates per ASTM C136 and AASHTO T 27.
- Particle size verification of catalyst substrates and battery electrode materials.
- Soil texture classification and sediment analysis per ASTM D2487 and D6913.
- Validation of milling and micronization processes in chemical and food manufacturing.
- Calibration and verification of laser diffraction and dynamic image analysis instruments using traceable sieve standards.
FAQ
What voltage and frequency options are available for the SS-30 model?
The SS-30 is configured for 115 V / 60 Hz operation. Equivalent variants include the SS-30F (230 V / 50 Hz) and SS-30S (230 V / 60 Hz), all sharing identical mechanical specifications and compliance profiles.
Can ISO-standard 200 mm test sieves be used with the SS-30?
Yes—the SS-30 accepts both ASTM-standard 8-inch (203 mm) and ISO 3310-1–compliant 200 mm diameter test sieves, provided they are Ro-Tap®-rated and fitted with compatible retaining rings.
Is the SS-30 suitable for wet sieving applications?
No. The SS-30 is strictly designed for dry-sieving procedures. Wet sieving requires specialized equipment with fluid handling, drainage, and corrosion-resistant construction not present in this model.
How does the SS-30 differ from the SS-33 dual-stack configuration?
The SS-33 features two independent 8-inch shaking decks operating simultaneously with identical motion parameters, enabling parallel testing or comparative analysis—whereas the SS-30 provides a single deck optimized for maximum sieve capacity per cycle.
Does Gilson provide calibration certificates or traceable verification services for the SS-30?
Gilson offers optional factory calibration verification reports upon request, documenting timer accuracy, tap count consistency, and oscillation frequency against NIST-traceable references—supporting internal QA and external audit readiness.
