Gilson SS-30F Ro-Tap® Sieve Shaker (230V / 50Hz)

Overview

The Gilson SS-30F Ro-Tap® Sieve Shaker is a precision-engineered mechanical sieve shaker manufactured by W.S. Tyler and distributed globally by Gilson, Inc. Designed in strict accordance with ASTM E11, ISO 3310-1, and USP , this instrument delivers standardized, reproducible particle size distribution analysis through synchronized horizontal orbital motion and vertical tapping action—mimicking the manual sieving technique while eliminating operator variability. The SS-30F operates at 230 V / 50 Hz and produces 278 oscillations and 150 taps per minute, ensuring consistent energy input across all sieve stacks. Its robust cast-iron frame, 1/4 HP induction motor, and vibration-dampening base provide long-term stability during high-cycle operation—critical for QC laboratories performing routine aggregate, pharmaceutical, mineral, or chemical powder testing.

Key Features

• Compliant mechanical sieving action: 278 rpm orbital rotation + 150 taps/min vertical impact, meeting ASTM D6913, D1140, and ISO 565 requirements
• Digital timer with 0.1-second resolution and 99-minute maximum duration for precise test repeatability
• Quick-adjust sieve support plate accommodates up to six full-height 8-inch (203 mm) test sieves or thirteen half-height sieves in a single stack
• Compatible with both ASTM-standard Tyler® mesh sieves and ISO 3310-1–compliant 200 mm diameter sieves
• Heavy-duty steel construction with bolt-down mounting capability for vibration isolation on laboratory benches
• Integrated motor thermal protection and overload circuitry for uninterrupted operation under continuous duty cycles

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). It is validated for use with standard W.S. Tyler® Ro-Tap® sieve frames in 8-inch (203 mm) diameter, including stainless steel, brass, and nylon-mesh configurations. All operational parameters—including tap frequency, amplitude, and timing—are traceable to NIST-traceable calibration standards. The device meets GLP documentation requirements when paired with audit-ready electronic timers and satisfies FDA 21 CFR Part 11 data integrity criteria when integrated with compliant LIMS or ELN systems. It is routinely employed in GMP-regulated environments for excipient qualification, catalyst screening, and raw material release testing.

Software & Data Management

While the SS-30F is a standalone electromechanical instrument without embedded firmware or network connectivity, its digital timer output can be interfaced with external data acquisition systems via relay-triggered TTL signals (optional accessory). Gilson’s companion software suite—SieveLog Pro™—supports batch logging of sieve test parameters (duration, sieve stack configuration, sample mass), automatic calculation of cumulative percent retained/passing, and generation of ASTM-compliant reports with digital signatures. All exported datasets include timestamped metadata, operator ID, and instrument serial number—enabling full traceability for internal audits and regulatory inspections.

Applications

• Quality control of construction aggregates, sand, and gravel per ASTM C136 and AASHTO T 27
• Pharmaceutical powder characterization for blend uniformity and dissolution rate prediction (USP )
• Mineral processing optimization through particle size distribution profiling of crushed ores
• Ceramic and refractory raw material grading prior to sintering
• Food ingredient consistency verification (e.g., flour, sugar, spices) per AOAC 970.21
• Environmental soil particle analysis per USDA NRCS Soil Survey Manual protocols

FAQ

What voltage and frequency does the SS-30F operate on?
The SS-30F is configured for 230 V / 50 Hz operation and draws 2.9 A under nominal load.
Can ISO-standard 200 mm sieves be used with the SS-30F?
Yes—the SS-30F accepts both 8-inch (203 mm) ASTM-standard sieves and ISO 3310-1–certified 200 mm diameter sieves using optional adapter rings.
Is the SS-30F suitable for wet sieving?
No—this model is designed exclusively for dry-sieving applications. For wet sieving, consult the Gilson SS-30W series or W.S. Tyler Hydro-Sieve® systems.
How many sieves can be stacked simultaneously?
Up to six full-height 8-inch sieves or thirteen half-height 8-inch sieves can be accommodated in a single stack.
Does the SS-30F include a sound enclosure?
No—the SS-30F is supplied as a standalone unit; the optional W.S. Tyler Sound Enclosure (Model SE-RT) must be ordered separately to reduce ambient noise below 65 dBA.
