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 profile—combining horizontal circular oscillation (278 cycles/min) with vertical tapping (150 taps/min)—to ensure uniform, reproducible sample stratification and separation across stacked test sieves. This dual-motion mechanism minimizes particle nesting and blinding, enabling high-fidelity granulometric data for quality control, R&D, and regulatory compliance workflows in pharmaceuticals, aggregates, ceramics, powders, and geotechnical laboratories. The SS-30F variant is specifically configured for 230 V / 50 Hz operation, making it suitable for laboratory environments across Europe, Asia-Pacific, and other 50 Hz grid regions.
Key Features
- Robust 1/4 HP induction motor delivering consistent torque and long-term operational stability under continuous duty cycles
- Digital electronic timer with 0.1-second resolution and programmable duration up to 99 minutes for precise test repeatability
- Quick-adjust sieve support plate accommodating up to six full-height 8-inch (203 mm) test sieves—or thirteen half-height sieves—within a single stack configuration
- Universal compatibility with both ASTM-standard and ISO-standard 200 mm diameter test sieves
- Heavy-duty cast-iron base and reinforced steel housing engineered for vibration damping and secure benchtop mounting
- Integrated safety interlock preventing operation when the clamping lid is not fully secured
Sample Compatibility & Compliance
The SS-30F supports dry-sieving applications for free-flowing, non-cohesive granular materials ranging from coarse aggregates (No. 4, 4.75 mm) down to fine powders (No. 635, 20 µm). Its motion profile meets the mechanical requirements specified in ASTM E11 Section 7.2.2 and ISO 3310-1 Annex A for standardized sieve analysis. When used with traceable, certified W.S. Tyler® test sieves—and operated within documented SOPs—the system supports GLP and GMP-aligned particle size testing protocols. Full audit trail capability is achievable when paired with compliant LIMS or ELN platforms supporting FDA 21 CFR Part 11 electronic record integrity.
Software & Data Management
While the SS-30F operates as a standalone electromechanical instrument without embedded firmware or network connectivity, its deterministic timing and repeatable motion profile enable seamless integration into validated digital workflows. Laboratories may pair the shaker with external data acquisition systems or digital balance interfaces via RS-232 or USB-to-serial adapters to automate result logging. Gilson’s optional Clean-N-STOR fraction collector accessory enables sequential, operator-independent collection of sieve fractions—reducing manual handling errors and supporting traceable mass balance calculations per USP <786> and ASTM C136.
Applications
- Pharmaceutical granulation and excipient characterization per USP <786> and ICH Q5A
- Aggregate gradation testing for asphalt and concrete compliance (ASTM C136, AASHTO T 27)
- Ceramic and metal powder quality assurance in additive manufacturing feedstock qualification
- Soil and sediment particle size analysis per ASTM D422 and ISO 14688-1
- Food ingredient particle distribution verification (e.g., flour, sugar, dairy powders) under HACCP and BRCGS frameworks
- Research-grade sieve calibration and method validation studies requiring NIST-traceable reference materials
FAQ
What voltage and frequency does the SS-30F operate on?
The SS-30F is configured for 230 V AC at 50 Hz operation, with a nominal current draw of 2.9 A.
Can ISO 200 mm test sieves be used with the SS-30F?
Yes—the SS-30F accepts standard 200 mm (8-inch) diameter test sieves conforming to ISO 3310-1, including stainless steel, brass, and nylon mesh variants.
Is the SS-30F compatible with noise-reduction enclosures?
Yes—it is fully compatible with W.S. Tyler® Sound Enclosures, which reduce operational noise by ≥25 dBA through acoustic foam-lined steel construction.
What is the maximum number of sieves supported in a single stack?
Up to six full-height 8-inch (203 mm) sieves, or thirteen half-height sieves, depending on the configured pan assembly.
Does the SS-30F include a built-in data logger or software interface?
No—the unit is electromechanical and timer-based; however, its consistent motion profile allows reliable synchronization with external balance and LIMS systems for automated reporting.
