Overview
The W.S. Tyler 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 particle stratification and efficient separation across stacked test sieves. This dual-motion mechanism minimizes particle agglomeration and promotes consistent bed movement, delivering high reproducibility essential for QC laboratories, raw material qualification, and R&D validation workflows. The SS-30F variant operates at 230 V / 50 Hz, making it suitable for international laboratories operating under European or Asian power standards while maintaining full compliance with global sieve analysis protocols.
Key Features
- Robust 1/4 HP induction motor engineered for continuous-duty operation and long-term mechanical stability
- Digital timer with 0.1-second resolution and programmable duration up to 99 minutes for precise test repeatability
- Quick-adjust sieve support plate accommodates full-height, half-height, or intermediate-height 8-inch (203 mm) test sieves without tools
- Modular mounting design allows secure bolt-down installation to laboratory benches or vibration-dampening platforms
- Compatible with both ASTM-standard 8-inch diameter sieves and ISO 200 mm round sieves, supporting interchangeable frame configurations
- Structural cast-iron base and reinforced steel housing provide rigidity against resonance-induced measurement drift
Sample Compatibility & Compliance
The SS-30F supports dry-sieving applications for granular solids ranging from coarse aggregates (No. 4, 4.75 mm) down to fine powders (No. 635, 20 µm). Its validated motion profile meets ASTM D6913, D1140, and C136 requirements for soil, cement, pharmaceutical excipients, metal powders, and ceramic precursors. All operational parameters—including tap frequency, orbital amplitude, and dwell time—are fixed per ASTM E323-22 to eliminate operator-dependent variability. The unit is CE-marked and conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions), supporting GLP-compliant documentation when integrated with audit-trail-capable LIMS or ELN systems.
Software & Data Management
While the SS-30F operates as a standalone electromechanical instrument, its deterministic timing and repeatable motion profile enable seamless integration into regulated environments. When paired with digital balance interfaces or automated fraction collectors (e.g., Clean-N-STOR™), weight data from retained fractions can be logged externally with timestamped metadata. For FDA 21 CFR Part 11 compliance, users may deploy third-party electronic lab notebook (ELN) platforms that capture instrument ID, operator credentials, start/stop timestamps, and sieve stack configuration—ensuring full traceability of each sieve analysis sequence.
Applications
- Quality control of bulk pharmaceutical ingredients per USP <786> and EP 2.9.32
- Particle size verification of catalysts, battery electrode slurries, and additive manufacturing metal powders
- Aggregate gradation testing in civil engineering labs per ASTM C136/C136M
- Food ingredient consistency checks (e.g., flour, sugar, spices) aligned with AOAC 992.03
- Mineral processing optimization through feedstock classification and product specification validation
FAQ
What voltage and frequency does the SS-30F operate at?
The SS-30F is configured for 230 V AC, 50 Hz operation with a rated current draw of 2.9 A.
Can ISO 200 mm sieves be used on the SS-30F?
Yes—the SS-30F accepts both ASTM-standard 8-inch (203 mm) and ISO 200 mm diameter test sieves using compatible adapter plates.
How many sieves can be stacked simultaneously?
Up to six full-height 8-inch sieves with a full-height pan, or thirteen half-height sieves with a half-height pan.
Is the Ro-Tap® motion profile adjustable?
No—the oscillation rate (278 cycles/min) and tap frequency (150 taps/min) are fixed to comply with ASTM E11 and ISO 3310-1 specifications.
Does the unit include a sound enclosure?
The SS-30F is supplied as a standalone shaker; optional W.S. Tyler Sound Enclosures (sold separately) reduce operational noise by ≥25 dB(A) for shared lab environments.
