Taylor SS30S Ro-Tap® Mechanical Sieve Shaker

Overview

The Taylor SS30S Ro-Tap® Mechanical Sieve Shaker is a precision-engineered, ASTM-compliant dry particle sizing instrument designed for standardized sieve analysis in quality control, R&D, and regulatory testing laboratories. Based on the proven Ro-Tap® principle—combining horizontal circular motion (278 oscillations per minute) with vertical tapping action (150 taps per minute)—this shaker replicates the manual sieving technique defined in ASTM E11, ASTM D6913, ISO 3310-1, and USP <786>. The SS30S variant operates at 230 V / 60 Hz and delivers high reproducibility across repeated test cycles, making it suitable for GMP-compliant environments where method validation and equipment qualification are required. Its robust cast-iron frame, 1/4 HP induction motor, and vibration-dampening base ensure stable operation even during extended-duration tests. Designed for use with full-height 8-inch (203 mm) test sieves, the SS30S accommodates up to six stacked sieves or thirteen half-height sieves—enabling efficient multi-fraction analysis of granular materials ranging from coarse aggregates to fine powders.

Key Features

• ASTM E11– and ISO 3310-1–compliant motion profile: 278 oscillations/min + 150 taps/min
• Digital timer with 0.1-second resolution and 99-minute maximum duration
• Quick-adjust sieve support plate for precise alignment and consistent clamping force
• Sturdy cast-iron housing with reinforced mounting points for benchtop bolting
• Thermally protected 1/4 HP AC induction motor rated for continuous-duty operation
• Compatibility with both ASTM-standard and ISO-standard 200 mm diameter sieves
• Integrated safety interlock preventing operation when lid is open

Sample Compatibility & Compliance

The SS30S supports dry, free-flowing particulate samples within the nominal size range of No. 4 (4.75 mm) to No. 635 (20 µm), as validated per ASTM D6913 and ISO 13320. It is routinely employed in cement, pharmaceutical excipient, mineral processing, food ingredient, and additive manufacturing powder characterization workflows. All mechanical components comply with CE marking requirements for machinery safety (2006/42/EC), and electrical design conforms to IEC 61000-6-3 (EMC emission standards). When used with validated sieve sets and documented SOPs, the system meets data integrity expectations under FDA 21 CFR Part 11 when paired with compliant laboratory information management systems (LIMS) for result recording.

Software & Data Management

While the SS30S is a standalone electromechanical instrument without embedded firmware or network connectivity, its deterministic timing and repeatable motion profile enable seamless integration into regulated workflows. Users may log test parameters—including sieve stack configuration, timer settings, sample mass, and environmental conditions—manually or via LIMS interfaces. For audit readiness, laboratories commonly implement paper-based or electronic batch records referencing ASTM E11 Annex A1 for equipment qualification (IQ/OQ) and routine performance verification (RPV). Optional accessories such as the Clean-N-STOR fraction collector facilitate traceable, contamination-controlled fraction handling and reduce post-sieving weighing errors.

Applications

• Particle size distribution (PSD) analysis of pharmaceutical granules and APIs per USP <786>
• Aggregate gradation testing in civil engineering labs per ASTM C136 and AASHTO T 27
• Quality assurance of catalysts, pigments, and ceramic powders in chemical manufacturing
• Feedstock screening for metal injection molding (MIM) and binder jetting processes
• Validation of milling and micronization process endpoints
• Compliance testing for ISO 8501-1 surface preparation abrasives

FAQ

What voltage and frequency does the SS30S model support?
The SS30S is configured for 230 V / 60 Hz operation with a current draw of 2.2 A.
Can the SS30S accommodate ISO-standard sieves?
Yes—it accepts 200 mm diameter ISO 3310-1 sieves in addition to standard 8-inch (203 mm) ASTM E11 frames.
Is the SS30S suitable for GLP or GMP environments?
Yes—its mechanical repeatability, absence of software-driven variables, and compatibility with IQ/OQ protocols make it appropriate for regulated quality systems.
How many sieves can be stacked simultaneously on the SS30S?
Up to six full-height 8-inch sieves or thirteen half-height 8-inch sieves, depending on stack configuration and pan selection.
Does the unit include a sound enclosure?
No—the SS30S is supplied as a standalone shaker; the optional W.S. Tyler Sound Enclosure (Model SE-1) must be ordered separately for noise reduction.
