Overview
The Tyler RO-TAP RX-29-10 is a precision-engineered mechanical sieve shaker designed to replicate standardized manual sieving protocols through synchronized vertical tapping and horizontal rotational motion. Developed by W.S. Tyler—a globally recognized leader in particle size analysis instrumentation—the RX-29-10 implements the ASTM E11-09 and ISO 3310-1 compliant dual-motion principle: a vertically oriented ¼-horsepower motor drives both rhythmic tapping (150 ± 10 taps per minute) and orbital rotation (278 ± 10 rpm), ensuring uniform particle stratification and efficient segregation across multi-layered sieve stacks. This kinematic profile minimizes particle agglomeration, reduces blinding, and eliminates dead zones—critical for reproducible dry-sieving results in regulated environments such as pharmaceutical quality control (QC), food safety testing, and mineral processing laboratories.
Key Features
- Robust cast-iron frame with vibration-dampening rubber feet ensures operational stability during extended runs.
- Dual-motion mechanism delivers consistent, repeatable energy transfer—optimized for both coarse aggregates (up to 125 mm) and fine powders down to 20 µm.
- Digitally controlled timer with 0.1-second resolution enables precise protocol adherence, supporting method validation under GLP and GMP frameworks.
- Modular sieve stack configuration accommodates up to six full-height (200 mm diameter) sieves plus thirteen half-height units—maximizing throughput without compromising stack integrity.
- Sealed motor housing prevents dust ingress and meets IP54-rated environmental protection standards for industrial laboratory settings.
- Standard 200 mm (8-inch) sieve platform conforms to NIST-traceable dimensional tolerances, ensuring interchangeability with certified reference sieves from global calibration providers.
Sample Compatibility & Compliance
The RX-29-10 is validated for dry-sieving of free-flowing, non-cohesive, and moderately cohesive particulates—including APIs, excipients, metal powders, catalysts, ceramics, agricultural grains, and mining concentrates. It supports compliance with pharmacopeial requirements (USP , EP 2.9.31), ASTM C136/C702 for aggregate gradation, and ISO 13320 for laser diffraction correlation studies. When paired with traceable Tyler stainless-steel or brass sieves (certified per ASTM E11 Annex A1), the system satisfies audit readiness for FDA 21 CFR Part 11 data integrity mandates when used with compliant software logging solutions. Optional R-30500 acoustic enclosure reduces ambient noise to ≤65 dB(A), meeting OSHA workplace exposure guidelines.
Software & Data Management
While the RX-29-10 operates as a standalone electromechanical instrument, its timer output signal is compatible with external data acquisition systems via TTL-level pulse triggering. Laboratories implementing electronic lab notebooks (ELNs) or LIMS platforms may integrate run parameters—including start time, duration, and operator ID—using optional relay interface modules. For full audit trail capability, users are advised to pair the shaker with Tyler’s RO-TAP Data Logger (sold separately), which records timestamped cycle counts, motor current draw, and thermal sensor feedback—supporting 21 CFR Part 11 electronic signature workflows when deployed on validated Windows-based hosts.
Applications
- Pharmaceutical: Granule size distribution analysis per USP ; blend uniformity assessment prior to tablet compression.
- Food & Beverage: Flour fineness grading (AACC Method 26-10A); spice particle consistency verification; cereal milling QC.
- Materials Science: Metal powder characterization for additive manufacturing feedstock qualification (ASTM F3049).
- Geotechnical & Mining: Soil gradation per ASTM D422; crushed rock and slag aggregate classification.
- Tobacco Industry: Cut filler and reconstituted tobacco sheet (RTS) particle sizing for combustion uniformity modeling.
- Chemicals & Polymers: Pigment dispersion screening; catalyst support particle integrity testing.
FAQ
What sieve standards does the RX-29-10 support?
It accepts all 200 mm (8-inch) diameter sieves conforming to ASTM E11, ISO 3310-1, and BS 410 specifications—including full-height, half-height, brass, stainless steel, polyester, and nylon mesh variants.
Can the RX-29-10 be used for wet sieving?
No—this model is strictly for dry-sieving applications. For aqueous dispersion analysis, Tyler offers the LA11112 water-sieving attachment (requires separate mounting kit) compatible with the RX-29-10 chassis.
Is calibration documentation provided with the unit?
The RX-29-10 ships with a factory performance certificate verifying tap frequency, rotational speed, and timer accuracy against NIST-traceable references. Full calibration services—including motor torque verification and motion trajectory mapping—are available through authorized Tyler service centers.
What maintenance is required?
Routine inspection of drive belt tension, tap hammer wear, and bearing lubrication every 500 operating hours is recommended. Replacement parts—including R-40041 leveling stands, 8491 stainless steel receivers, and 8577 high-density cleaning brushes—are stocked globally.
How does the RX-29-10 compare to rotary-only or vibratory shakers?
Unlike single-axis vibratory shakers, the RO-TAP’s dual-motion architecture provides superior particle fluidization and stratification—particularly for dense, irregular, or electrostatically charged materials where conventional methods yield poor recovery or skewed D10/D50/D90 values.
