Overview
The Gilson SS-12R Tapping Sieve Shaker is a precision-engineered mechanical sieving instrument designed for standardized particle size distribution analysis in accordance with ASTM E11, ISO 3310-1, and USP <786>. It employs a dual-mode tapping and rotational motion principle—combining vertical tapping (48 taps per minute) with continuous 360° orbital rotation—to overcome the limitations of linear reciprocating shakers. This unique motion profile eliminates “dead zones” by ensuring particles roll freely in all directions while repeated upward tapping reorients aggregates and facilitates near-size particles to pass through mesh apertures. The SS-12R is optimized for high-volume, regulatory-compliant sieve analysis in QC laboratories, aggregate testing facilities, pharmaceutical development labs, and mineral processing R&D environments.
Key Features
- Dual-action mechanism: 48 vertical taps/min + continuous 360° orbital rotation for superior particle reorientation and mesh penetration
- High-capacity stack compatibility: accommodates up to thirteen 12-inch (305 mm) half-height sieves, ten intermediate-height, or six full-height sieves—including ISO 300 mm frames
- Universal adapter included: enables seamless integration of 8-inch (203 mm) or ISO 200 mm sieves into the 12-inch platform
- Patented EZ-Clamp system: one-button engagement with sliding clamp rod and twist-lock knob ensures rapid, repeatable, and vibration-resistant stack fixation
- Balanced internal counterweight architecture: delivers stable operation without floor anchoring or external leveling
- Digital timer controller: programmable test duration from 1 second to 99 minutes 59 seconds with automatic stop and reset functionality
- Robust drive system: 1/3 HP heavy-duty induction motor with thermal overload protection
- Industrial-grade housing: powder-coated steel enclosure rated for continuous laboratory use
- Global power compatibility: available in 115 V / 60 Hz (North America) and 230 V / 50 Hz (EU/UK/Asia) configurations
Sample Compatibility & Compliance
The SS-12R supports dry-sieving applications across a broad material spectrum—including soils, sands, crushed aggregates, metal powders, catalysts, APIs, excipients, and ceramic granules. Its recommended particle size range spans 2 inches (50 mm) down to No. 635 (20 µm), though actual effective resolution depends on sample density, shape, moisture content, and cohesivity. All operational parameters comply with ASTM D6913 (soil particle analysis), ASTM C136 (aggregate gradation), ISO 2591-1 (general sieving), and pharmacopeial requirements for uniformity of dosage units. When paired with certified ASTM E11 or ISO 3310-1 test sieves, the system meets GLP documentation standards and supports 21 CFR Part 11–compliant data integrity workflows when integrated with validated LIMS or ELN platforms.
Software & Data Management
The SS-12R operates as a standalone electromechanical instrument with no embedded firmware or network interface. Its digital controller provides non-volatile time logging and manual start/stop functions but does not generate electronic records. For audit-ready traceability, users integrate the shaker into validated laboratory workflows via external timers with timestamped output or synchronized with balance and data acquisition systems. Optional accessories—including the SSA-805R acoustic enclosure (reducing noise to ≤72 dBA) and Clean-N-STOR fraction collectors—enable closed-loop sieving, dust containment, and gravimetric fraction handling in compliance with OSHA PEL and ISO 14644 cleanroom practices.
Applications
- Aggregate gradation testing for ASTM C136 and AASHTO T 27 compliance in civil engineering labs
- Pharmaceutical granule sizing and blend uniformity assessment per USP <786> and ICH Q5C
- Mineralogical classification of ores and tailings in metallurgical QA/QC
- Ceramic and additive manufacturing powder characterization (e.g., flowability screening)
- Environmental soil texture analysis per USDA NRCS methodology
- Research-scale particle breakage and attrition studies under controlled mechanical stress
FAQ
What sieve frame sizes does the SS-12R support natively?
The SS-12R is configured for 12-inch (305 mm) diameter sieves, including full-height, intermediate-height, and half-height variants. With the included adapter, it also accepts 8-inch (203 mm) and ISO 200 mm frames.
Is the SS-12R suitable for wet sieving?
No—it is designed exclusively for dry-sieving applications. Wet sieving requires specialized equipment with fluid handling, drainage, and corrosion-resistant construction.
Does the SS-12R meet FDA 21 CFR Part 11 requirements?
As a stand-alone mechanical device without electronic data generation or user authentication, the SS-12R itself is not subject to Part 11. However, its consistent, repeatable operation supports Part 11–compliant processes when paired with validated electronic record systems.
Can the tapping frequency be adjusted?
No—the tapping rate is fixed at 48 taps per minute per ASTM E11 and ISO 3310-1 specifications to ensure method equivalence and inter-laboratory reproducibility.
What maintenance is required?
Routine inspection of the EZ-Clamp mechanism, motor ventilation grilles, and rubber isolation feet is recommended quarterly. Lubrication is not required—the sealed induction motor and bearing assemblies are maintenance-free for ≥10,000 operating hours.
