Overview
The Gilson SS-30F 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—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 screen blinding while maximizing reproducibility in granular material testing. The SS-30F variant is specifically configured for international laboratories operating on 230 V / 50 Hz power supplies, making it suitable for regulatory-compliant QC environments across Europe, Asia, and Oceania. Its robust cast-iron frame, bolt-down mounting capability, and vibration-dampening base provide mechanical stability during extended operation, supporting GMP-aligned workflows where equipment qualification and routine performance verification are required.
Key Features
- Ro-Tap® patented dual-motion drive system: 278 rpm horizontal oscillation + 150 rpm vertical tapping, calibrated per ASTM D6913 and ISO 2591-1
- Digital timer with 0.1-second resolution and 99-minute maximum duration, supporting repeatable test protocols and audit-ready timing logs
- Adjustable sieve support plate accommodates up to six full-height 8-inch (203 mm) test sieves or thirteen half-height sieves in a single stack
- 1/4 HP induction motor with thermal overload protection ensures consistent torque delivery under variable load conditions
- Compatibility with both ASTM-standard and ISO-standard sieves—including 200 mm diameter formats—enabling method flexibility across global regulatory frameworks
- Bolt-mounting interface allows secure installation to laboratory benches or dedicated isolation platforms to reduce ambient vibration transmission
Sample Compatibility & Compliance
The SS-30F supports dry-sieving applications for powders, granules, aggregates, pharmaceutical excipients, catalysts, and mineral ores within the nominal particle size range of No. 4 to No. 635 (4.75 mm to 20 µm). Its mechanical design conforms to the dimensional and operational requirements specified in ASTM E11 (Specification for Woven Wire Test Sieve Cloth and Test Sieves), ISO 3310-1 (Test Sieves — Technical Requirements and Testing — Part 1: Test Sieves of Metal Wire Cloth), and USP <786> (Particle Size Distribution). When used with traceable, certified reference sieves and validated SOPs, the system supports data integrity requirements under FDA 21 CFR Part 11 when integrated with compliant LIMS or ELN platforms. Routine calibration verification—using certified gauge blocks and stopwatch validation—meets GLP documentation standards.
Software & Data Management
The SS-30F operates as a standalone electromechanical instrument without embedded firmware or network connectivity. However, its precise digital timer output (0.1 s resolution) enables seamless integration into laboratory data management systems via external time-stamped logging devices or programmable logic controllers (PLCs). For regulated environments, users may pair the shaker with electronic lab notebooks (ELNs) that capture operator ID, sieve stack configuration, run duration, and environmental conditions (e.g., temperature/humidity) as metadata. Audit trails for timer calibration and mechanical maintenance—including motor current draw verification and tap amplitude measurement—are recommended at intervals defined by internal quality procedures or ISO/IEC 17025 accreditation requirements.
Applications
- Quality control of bulk pharmaceutical powders prior to tablet compression or capsule filling
- Aggregate gradation analysis in civil engineering laboratories per ASTM C136 and AASHTO T 27
- Characterization of ceramic raw materials and battery cathode precursors
- Validation of milling process endpoints in chemical manufacturing
- Environmental sediment analysis under EPA Method 1695 (particle size distribution of soil)
- Research-grade particle segregation studies requiring high inter-laboratory reproducibility
FAQ
What voltage and frequency configurations are available for the SS-30 series?
The SS-30F model is rated for 230 V / 50 Hz operation; other variants include SS-30 (115 V / 60 Hz) and SS-30S (230 V / 60 Hz). All share identical mechanical specifications and timing accuracy.
Can the SS-30F accommodate ISO 200 mm test sieves?
Yes—the unit accepts standard 200 mm (8-inch) diameter sieves, including those manufactured to ISO 3310-1 tolerances, using the same full-height or half-height stacking configurations.
Is the Ro-Tap® motion profile adjustable?
No—the oscillation and tapping frequencies are mechanically fixed at 278 and 150 cycles per minute respectively, per ASTM E11 compliance requirements. This fixed motion ensures method equivalence across laboratories.
What maintenance is required to sustain calibration integrity?
Annual verification of tap amplitude (±1 mm tolerance), oscillation speed (±2 rpm), and timer accuracy (±0.1 s over 60 s) is recommended. Motor lubrication is not required—the sealed induction motor is maintenance-free for rated service life.
Does Gilson provide IQ/OQ documentation support?
Yes—Gilson supplies factory-verified performance certificates and configurable IQ/OQ templates aligned with ASTM E2500 and Annex 11 principles, supporting equipment qualification in regulated pharmaceutical and medical device facilities.
