Gilson SS-30F Ro-Tap® Sieve Shaker (230V / 50Hz)

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 dual-motion protocol defined in ASTM D6913 and D422—combining horizontal circular oscillation (278 cycles/min) with vertical tapping (150 taps/min)—to ensure reproducible, operator-independent sieving results. This electromechanical shaker employs a robust ¼ HP induction motor and a fully enclosed cam-driven mechanism to deliver consistent amplitude and frequency over extended duty cycles. Its design prioritizes mechanical stability: the unit features reinforced cast-iron base plates, vibration-dampening rubber feet, and optional bench-mounting capability for high-volume QC laboratories where long-term repeatability and minimal drift are critical. The SS-30F variant is specifically configured for international operation at 230V / 50Hz, making it compliant with European, Asian, and Oceania electrical infrastructure standards while maintaining full functional equivalence to its 115V/60Hz counterparts.

Key Features

• Dual-motion mechanism: Simultaneous horizontal orbital motion (278 rpm) and vertical tapping (150 taps/min), precisely calibrated per ASTM E11 Annex A3 and ISO 3310-1 Clause 6.2
• Digital timer with 0.1-second resolution and 99-minute maximum duration, supporting GLP-compliant test logging via external data capture
• Quick-adjust sieve support plate accommodates up to six full-height 8-inch (203 mm) test sieves or thirteen half-height sieves—compatible with both ASTM-standard Tyler® mesh and ISO 565/3310-1 metric aperture frames
• Heavy-duty cast-iron housing and cam assembly engineered for >10,000 hours of continuous operation under industrial laboratory conditions
• Integrated overload protection and thermal cut-off circuitry compliant with IEC 61000-4-5 surge immunity and EN 60335-1 safety requirements
• Optional acoustic enclosure (W.S. Tyler SoundShield®) reduces operational noise to ≤65 dBA at 1 m distance, meeting ISO 7779 and EU Directive 2006/42/EC occupational exposure limits

Sample Compatibility & Compliance

The SS-30F supports dry-sieving applications across granular solids ranging from coarse aggregates (No. 4, 4.75 mm) to fine powders (No. 635, 20 µm). Its 8-inch (203 mm) sieve platform accepts standard Tyler®, ASTM E11, and ISO 3310-1 conforming frames—including stainless steel, brass, and electroformed mesh variants—in full-height, half-height, and intermediate configurations. All motion parameters are validated per ASTM D6913-22 Section 7.2 and ISO 2591-1:2022 Annex B. The instrument meets essential requirements of the EU Machinery Directive 2006/42/EC and carries CE marking. For regulated pharmaceutical and food testing environments, the shaker’s deterministic timing and mechanical traceability support 21 CFR Part 11-compliant workflows when paired with validated electronic lab notebooks (ELNs) or LIMS-integrated timers.

Software & Data Management

While the SS-30F operates as a standalone electromechanical device without embedded firmware or network interfaces, its digital timer output (TTL-level pulse signal) is compatible with third-party data acquisition systems (e.g., LabVIEW, MATLAB Data Acquisition Toolbox) for automated start/stop triggering and timestamped event logging. Gilson provides calibration certificates traceable to NIST standards upon request, including verification of tap frequency, oscillation amplitude (±0.5 mm), and timer accuracy (±0.1 sec over 99 min). Routine maintenance logs, calibration records, and performance verification reports align with ISO/IEC 17025:2017 clause 6.4.10 and ASTM D6913 Annex X2 guidance on equipment qualification.

Applications

• Quality control of mineral aggregates, cement clinker, and asphaltic binders per ASTM C136/C136M and EN 933-1
• Pharmaceutical granule and excipient sizing per USP <786> and EP 2.9.31
• Ceramic powder characterization in R&D labs requiring ISO 13320-compliant dry dispersion prior to laser diffraction
• Soil texture analysis in geotechnical and environmental testing per ASTM D422 and ISO 14688-1
• Food ingredient particle distribution validation (e.g., flour, sugar, dairy powders) aligned with FDA Food Safety Modernization Act (FSMA) preventive controls
• Recycled material screening for construction and demolition waste processing per ASTM D5239

FAQ

Is the SS-30F compatible with ISO-standard 200 mm test sieves?
Yes—the SS-30F accepts all 200 mm (8-inch) diameter sieves conforming to ISO 3310-1, ASTM E11, and BS 410 specifications, including stainless steel, brass, and nylon mesh variants.
Does the unit require annual recalibration?
Per ISO/IEC 17025 and ASTM D6913, verification of motion parameters (tap count, oscillation rate, timer accuracy) is recommended before each use series or at least daily in high-throughput labs; formal recalibration is advised every 12 months or after mechanical service.
Can the SS-30F be integrated into a LIMS environment?
While the shaker has no native network interface, its TTL timer output enables hardware-triggered data capture via PLCs or DAQ modules, allowing synchronization with LIMS timestamps and sample IDs when used with barcode-scanned sieve sets.
What safety certifications does the SS-30F carry?
It is CE-marked per 2006/42/EC (Machinery Directive), RoHS 2011/65/EU compliant, and tested to EN 60335-1 for electrical safety; full test reports available upon request.
Is bench mounting mandatory for accurate results?
Bench mounting is strongly recommended—and required for ASTM D6913 compliance—to eliminate resonant coupling with lab furniture and ensure consistent energy transfer to the sieve stack. Rubber isolation feet alone are insufficient for certified testing.
