Endecotts Octagon 200 Digital Sieve Shaker

Overview

The Endecotts Octagon 200 Digital Sieve Shaker is a precision-engineered electromagnetic sieve shaker designed for reproducible, standards-compliant particle size distribution analysis in laboratory and quality control environments. Unlike mechanically driven rotary or tapping shakers, the Octagon 200 employs a patented electromagnetic actuation system that generates controlled three-dimensional oscillatory motion—comprising vertical acceleration, lateral displacement, and gentle rotational agitation—optimized to maximize particle stratification and sieve penetration while minimizing blinding and agglomeration. This motion profile ensures rapid, uniform sample dispersion across the full active area of each sieve, significantly improving separation efficiency and statistical reliability—particularly for challenging materials such as cohesive powders, moist granules, or irregularly shaped aggregates. Built and calibrated in accordance with BS 410:2019, ISO 3310-1:2016 (metal wire cloth), ISO 3310-2:2016 (perforated plate), and ASTM E11–22, the instrument delivers traceable, auditable performance suitable for GLP, GMP, and ISO/IEC 17025-accredited laboratories.

Key Features

• Electromagnetic drive mechanism with zero rotating parts—eliminates mechanical wear, lubrication requirements, and long-term calibration drift.
• Digital controller with intuitive interface for precise setting of duration (0:10–99:59 min), amplitude (10 discrete steps from 0 to 3 mm), and vibration mode (continuous or programmable interval).
• Interval vibration function enables automatic “on/off” cycling to dislodge near-mesh particles and restore open area—critical for wet screening or high-fines content samples.
• Patented quick-action clamping system secures 200 mm (8 in) sieves firmly without over-compression, preserving mesh integrity and enabling repeatable tensioning across multiple test runs.
• Non-metallic isolation springs and elastomeric damping mounts reduce transmitted vibration by >85%, ensuring stable operation on standard lab benches and compliance with workplace noise directives (<65 dB(A)).
• Robust cast-aluminum housing with IP54-rated enclosure protects internal electronics from dust ingress and incidental splashes during wet-sieving protocols.
• Modular stack configuration supports up to 8 full-height or 18 half-height 200 mm sieves; maximum stack height of 450 mm accommodates multi-stage analysis per ASTM D6913 or ISO 17892-4.

Sample Compatibility & Compliance

The Octagon 200 is validated for both dry and wet sieving applications across a broad spectrum of particulate materials—including mineral aggregates, pharmaceutical excipients, catalysts, metal powders, food ingredients, soil specimens, and ceramic precursors. Its 3D motion profile demonstrates superior performance with low-density, electrostatic, or hygroscopic samples that typically suffer from poor fluidization in conventional shakers. All units are supplied with full traceability documentation, including individual conformity certificates referencing BS 410, ISO 3310-1/-2, and ASTM E11. Each device bears a unique serial number registered in Endecotts’ UK-based calibration registry, supporting audit readiness for FDA 21 CFR Part 11 (when integrated with compliant LIMS), ISO 9001, and UKAS-accredited testing workflows.

Software & Data Management

While the Octagon 200 operates as a standalone hardware platform, its digital timer and programmable interval logic provide deterministic, repeatable run parameters essential for SOP-driven environments. For laboratories requiring electronic recordkeeping, the instrument’s fixed parameter sets (time, amplitude, mode) can be documented within ELN systems or linked to validated data acquisition software via external relay triggers (optional accessory). Full maintenance logs—including service intervals, amplitude verification records, and clamp torque validation—are recommended per ISO/IEC 17025 Clause 6.4.2 and must be retained for ≥5 years in regulated settings. Firmware updates (if issued) are distributed exclusively through Endecotts’ authorized service partners and accompanied by change-control documentation.

Applications

• Quality assurance of raw materials and finished products in pharmaceutical manufacturing (e.g., API particle sizing per USP ).
• Soil classification and gradation testing per ASTM D6913/D422 and BS 1377-2.
• Aggregate grading for asphalt and concrete mix design (EN 933-1, AASHTO T 27).
• Food powder flowability assessment and contaminant screening (e.g., foreign particle detection in flour or spices).
• Research-grade particle engineering studies involving milling, granulation, or spray drying process optimization.
• Environmental sediment analysis and waste characterization under ISO 11277 and EPA Method 1684.

FAQ

Is the Octagon 200 compatible with non-Endecotts sieves?
Yes—provided they conform to ISO 3310-1 or ASTM E11 dimensional tolerances for 200 mm diameter frames and possess flat, rigid rims. However, only Endecotts-certified sieves carry full traceability to BS 410 and Kitemark accreditation.
What maintenance is required for long-term accuracy?
No routine maintenance is needed due to the absence of moving parts. Annual amplitude verification using a certified accelerometer and visual inspection of clamp integrity are recommended per ISO/IEC 17025.
Can the unit be used for wet sieving without risk of electrical hazard?
Yes—the IP54-rated enclosure and isolated power supply meet IEC 61000-6-3 for industrial electromagnetic compatibility. Always use CE-marked water traps and ensure drainage channels remain unobstructed.
Does the controller support password-protected parameter locking?
No—the front-panel interface lacks user-level access control. Parameter security must be enforced at the procedural level (e.g., SOP-controlled access, supervised operation).
Is calibration certification included with shipment?
Each unit ships with a Factory Calibration Certificate stating conformance to amplitude linearity (±0.1 mm), timer accuracy (±0.5 s/min), and frequency stability (±10 rpm at 50 Hz), traceable to NPL (UK) standards.
