Endecotts Octagon 200CL Digital Sieve Shaker

Overview

The Endecotts Octagon 200CL is a precision-engineered digital sieve shaker designed for standardized particle size distribution analysis in compliance with ISO 3310-1, ASTM E11, and BS 410. Utilizing electromagnetic drive technology, it delivers consistent, low-maintenance vibratory motion to ensure high reproducibility across repeated sieving cycles. Unlike mechanical cam or rotary shakers, the electromagnetic actuator eliminates gear wear, backlash, and lubrication requirements—enhancing long-term calibration stability and reducing operational downtime. The instrument is optimized for laboratory and quality control environments where traceable, auditable, and repeatable dry and wet sieving of granular materials is essential. Its rigid cast-aluminum housing and balanced dynamic architecture minimize structural resonance, supporting accurate mass-based fractionation of particles from 20 µm to 125 µm—within the nominal range of standard test sieves (ISO/ASTM-compliant 100 mm and 200 mm diameter meshes).

Key Features

• Electromagnetic drive system with zero mechanical wear—no belts, cams, or bearings requiring periodic replacement
• Digital timer with 0.1 s resolution and programmable duration up to 99 minutes 59 seconds
• 10-step adjustable amplitude control (0–3 mm peak-to-peak displacement), enabling method-specific optimization for fragile or cohesive samples
• Stack capacity for up to eight full-height 200 mm-diameter sieves—or sixteen 100 mm sieves—facilitating multi-stage分级 without manual reconfiguration
• Integrated sample retention tray and splash guard compatible with wet sieving protocols per ISO 2591-1
• Compact footprint (418 × 232 × 435 mm) and 43 kg net weight—designed for benchtop deployment in regulated laboratories and mobile QC units
• Individual serial-numbered sieve frames and certified traceability documentation aligned with GLP and GMP documentation requirements

Sample Compatibility & Compliance

The Octagon 200CL accommodates a broad spectrum of solid particulates including soils, pharmaceutical granules, food powders (e.g., flour, spices, dairy powders), construction aggregates (sand, cement), catalysts, ceramics, and tobacco cut filler. It supports both dry sieving (for free-flowing, non-hygroscopic materials) and wet sieving (for fine, agglomerated, or moisture-sensitive fractions), with optional stainless-steel liquid collection trays and sealed gasket interfaces. All manufactured sieves comply with ISO 3310-1 tolerances for mesh opening accuracy (±2.5% for apertures ≥63 µm) and wire diameter consistency. Each sieve carries a unique serial number linked to its calibration certificate—enabling full audit trail support for FDA 21 CFR Part 11–compliant workflows when integrated with validated LIMS or ELN systems.

Software & Data Management

While the Octagon 200CL operates as a standalone hardware platform, its digital timer and amplitude settings are fully configurable via front-panel membrane keypad and LCD display—ensuring method reproducibility without external software dependency. For laboratories implementing electronic record-keeping, Endecotts provides optional CSV export templates (via USB-connected data loggers) to capture run parameters (start time, duration, amplitude setting, sieve stack configuration) alongside operator ID and batch reference. These logs align with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) and support 21 CFR Part 11 audit readiness when paired with appropriate access controls and electronic signatures.

Applications

• Pharmaceutical: Excipient particle sizing per USP and regulatory submissions requiring ISO 13320-aligned granulometric data
• Food & Agriculture: Flour fineness testing (AACC Method 26–10A), spice particle uniformity, and grain milling QA
• Construction Materials: Sand gradation analysis per ASTM C136/C136M and EN 933-1
• Environmental Testing: Soil texture classification (USDA textural triangle) and sediment particle distribution
• Academic Research: Teaching particle mechanics, sieve analysis fundamentals, and method validation studies
• Chemical Manufacturing: Catalyst support material grading and pigment dispersion characterization

FAQ

Is the Octagon 200CL compliant with ISO 3310-1 and ASTM E11?
Yes—both the shaker’s motion profile and all supplied test sieves are manufactured and certified to meet ISO 3310-1 (2019) and ASTM E11-22 dimensional and tolerance specifications.
Can it perform wet sieving with recirculating water systems?
It supports static wet sieving with gravity-fed rinse; integration with external pump-based recirculation requires custom mounting brackets and is not covered under standard warranty.
What sieve diameters does it accept?
Standard configurations support 200 mm full-height stacked sieves; optional adapters allow use of 100 mm sieves in dual-stack arrangements.
Does Endecotts provide calibration certificates with each unit?
Each Octagon 200CL ships with a factory-issued performance verification report; individual sieve calibration certificates are provided separately per ISO/IEC 17025-accredited metrology lab.
Is routine maintenance required beyond cleaning?
No scheduled maintenance is specified—the electromagnetic actuator has no consumable parts, and the unit requires only periodic inspection of clamp integrity and sieve frame alignment.
