Endecotts EFL300 Electromagnetic Sieve Shaker

Overview

The Endecotts EFL300 Electromagnetic Sieve Shaker is a precision-engineered laboratory and industrial particle size analysis instrument designed for reproducible, standardized dry and wet sieving in accordance with ISO 3310-1, ASTM E11, and USP . Unlike traditional mechanical shakers relying on eccentric cam drives, the EFL300 employs a fully electromagnetic actuation system that delivers consistent 3D horizontal circular motion—ensuring uniform energy distribution across the entire sieve surface. This principle eliminates mechanical wear, reduces maintenance intervals, and enhances long-term measurement stability. Its modular architecture supports both full-height (6-sieve) and half-height (12-sieve) configurations, accommodating standard sieve diameters from 100 mm to 315 mm (8″ to 12″), making it compatible with globally accepted test sieve series including ISO, ASTM, and DIN specifications. The unit’s compact footprint (427 × 240 mm base), low center of gravity, and IP54-rated enclosure enable flexible deployment—whether mounted directly onto a reinforced lab bench or secured to a dedicated floor stand—without requiring structural anchoring or vibration isolation platforms.

Key Features

• Electromagnetic drive system delivering precise, repeatable 3D circular motion without mechanical backlash or gear wear
• Digital amplitude control (0–2 mm, 10 discrete steps) synchronized with real-time frequency stabilization at 3000 rpm (50 Hz)
• Benchtop- and floor-mountable design (45 kg net weight, optimized mass distribution) suitable for ISO 17025-accredited labs and GMP-compliant production environments
• Quick-release clamp mechanism enabling tool-free sieve stack assembly/disassembly within seconds
• Integrated digital timer with 10-second to 99-minute 55-second resolution, supporting multi-stage sequential sieving protocols
• IP54-rated housing protecting internal electronics against dust ingress and water splashes during wet sieving operations
• Universal single-phase power input with region-specific voltage adaptation (e.g., 230 V ±10% / 50 Hz or 120 V ±10% / 60 Hz)

Sample Compatibility & Compliance

The EFL300 accommodates sample masses up to 6 kg per run, supporting coarse aggregates (up to 40 mm), fine powders (down to 20 µm), and intermediate granular materials such as pharmaceutical excipients, metal powders, catalysts, ceramics, and mineral ores. Its ability to perform both dry and wet sieving—including suspension-based particle separation using standardized liquid media—aligns with ISO 2591-1 and ASTM C136/C702 requirements. All mechanical interfaces comply with EN 61000-6-2 (immunity) and EN 61000-6-3 (emission) standards. CE marking confirms conformity with EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. For regulated industries, the absence of analog dials or manual calibration points simplifies IQ/OQ documentation, while the deterministic amplitude-frequency relationship supports audit-ready traceability under FDA 21 CFR Part 11 when integrated with compliant LIMS or ELN systems.

Software & Data Management

While the EFL300 operates as a standalone instrument with local digital controls, its RS-232 and optional Ethernet interface enable integration into centralized laboratory automation frameworks. Third-party software—including Endecotts’ proprietary SieveSoft™ (v3.2+)—supports method storage, parameter logging (amplitude, time, frequency), and automated report generation compliant with GLP documentation templates. All timestamped operational data (start/stop times, amplitude settings, total run cycles) are retained internally for ≥10,000 sessions and exportable via CSV or XML for statistical process control (SPC) analysis. No cloud dependency or subscription licensing is required; firmware updates are delivered via secure USB flash drive with cryptographic signature verification.

Applications

• Quality control of bulk pharmaceutical powders per USP and EP 2.9.32
• Particle size distribution analysis of cement, fly ash, and slag in construction materials testing labs
• Classification validation of additive manufacturing metal powders (e.g., Ti-6Al-4V, Inconel 718) per ASTM F3049
• Routine QC of food-grade starches, flour, sugar, and dairy powders under BRCGS and IFS standards
• Geotechnical soil gradation testing per ASTM D6913 and AASHTO T 27
• Recycled aggregate sizing for circular economy compliance reporting

FAQ

Is the EFL300 suitable for regulatory submissions in pharmaceutical manufacturing?
Yes—the deterministic electromagnetic drive, digital parameter locking, and audit-trail-capable data export meet core expectations for equipment used in GMP environments, particularly when paired with validated software and documented SOPs.
Can the EFL300 be calibrated in-house?
Amplitude and frequency verification can be performed using traceable laser vibrometry or certified accelerometer-based metrology kits; Endecotts provides calibration certificates (ISO/IEC 17025-accredited) upon request.
What sieve frame heights does the EFL300 support?
Standard configuration accepts either six 50-mm full-height sieves or twelve 25-mm half-height sieves—both configured for 300-mm diameter frames with integrated lid and receiver pan.
Does the unit require compressed air or external cooling?
No—electromagnetic actuation generates negligible heat; no auxiliary utilities beyond standard AC power are needed.
How is wet sieving implemented safely?
The IP54 enclosure, corrosion-resistant stainless-steel clamps, and sealed motor housing permit direct use with aqueous or ethanol-based suspensions; drain ports and optional splash guards are available as accessories.
