Overview
The OCTAGON DIGITAL 2000 is a precision-engineered mechanical sieve shaker designed for standardized particle size distribution analysis in quality control, R&D, and regulatory-compliant laboratories. It operates on the principle of horizontal circular motion with controlled amplitude and frequency—optimized to ensure uniform energy transfer across stacked sieve assemblies. Unlike orbital or tapping mechanisms, this unit employs a robust eccentric drive system that replicates the reproducible motion required by international standards including ISO 2591-1, ASTM E11, and BS 410:2019. Its rigid cast-iron base and vibration-dampening feet minimize transmission of kinetic energy to adjacent equipment, supporting stable operation in shared analytical environments. The instrument is intended for dry-sieving applications involving granular solids, metal powders, pharmaceutical excipients, aggregates, and ceramic raw materials—where compliance with sieve calibration traceability and mechanical repeatability is essential.
Key Features
- Digital display interface with intuitive push-button controls for precise time setting (1 s–99 min 59 s), amplitude selection (3 amplitude levels), and real-time operational status feedback.
- Vibration-isolated clamping system featuring quick-release, anti-vibration locking levers—ensuring secure retention of stacked sieves without frame deformation or lateral slippage during extended shaking cycles.
- Structural integration with BS 410:2019-certified sieve manufacturers: all compatible 200 mm (8 in) diameter test sieves are supplied with NIST-traceable calibration certificates and laser-etched identification for audit readiness.
- EC Machinery Directive 2006/42/EC certified design, incorporating dual safety interlocks, thermal overload protection, and IP20-rated electrical enclosure—validated for continuous-duty operation in ISO 17025-accredited testing facilities.
- Modular sieve stack compatibility: accommodates either eight full-height (100 mm depth) or sixteen half-height (50 mm depth) 200 mm sieves—enabling flexible method development for multi-fraction analyses per USP & Ph. Eur. general chapters and 2.9.32.
Sample Compatibility & Compliance
The OCTAGON DIGITAL 2000 supports dry particulate samples ranging from coarse aggregates (>4 mm) down to fine powders (≥20 µm), provided material moisture content remains below 1% w/w to prevent agglomeration. It is routinely deployed in GMP-regulated environments for sieve validation studies under ICH Q5A and FDA Guidance for Industry: Powder Flow and Sieve Analysis. All test sieve sets used with this shaker must conform to BS 410:2019 dimensional tolerances and wire mesh specifications—including nominal aperture sizes from 20 µm to 125 mm. The instrument itself does not perform wet sieving or air jet dispersion; users requiring such capabilities should consider complementary instrumentation such as hydraulic or sonic sieving systems.
Software & Data Management
While the OCTAGON DIGITAL 2000 is a standalone electromechanical device without embedded software or network connectivity, its operational parameters are fully documentable within laboratory information management systems (LIMS) and electronic lab notebooks (ELN). Time, amplitude, and sieve stack configuration are manually recorded per SOPs aligned with 21 CFR Part 11 requirements—supporting audit trails when paired with controlled documentation workflows. Endecotts provides comprehensive calibration verification protocols, including amplitude verification using certified accelerometers and timing accuracy checks traceable to UKAS-accredited time standards.
Applications
- Pharmaceutical: Excipient particle sizing per USP , blend uniformity assessment, and granulation endpoint determination.
- Construction Materials: Gradation analysis of sand, gravel, and crushed stone per ASTM C136/C136M and EN 933-1.
- Food & Agriculture: Flour particle distribution, spice grinding consistency, and feed pellet fineness testing.
- Metallurgy & Additive Manufacturing: Metal powder classification prior to sintering or laser powder bed fusion (LPBF) processes.
- Environmental Testing: Soil texture analysis (sand/silt/clay separation) in accordance with USDA NRCS methods.
FAQ
Is the OCTAGON DIGITAL 2000 suitable for wet sieving?
No—it is strictly designed for dry-sieving applications. Wet sieving requires pressurized liquid delivery and corrosion-resistant construction not present in this model.
Can it be integrated into automated lab workflows?
Not natively; however, external programmable logic controllers (PLCs) or relay-based timers may be interfaced via its dry-contact start/stop terminals for semi-automated batch processing.
Does Endecotts supply certified reference sieves for this unit?
Yes—Endecotts manufactures BS 410:2019-compliant test sieves with UKAS-accredited calibration reports, available in stainless steel or brass with apertures from 20 µm to 125 mm.
What maintenance is required to sustain metrological performance?
Annual verification of amplitude consistency and timer accuracy is recommended; drive belt tension and bearing lubrication should be inspected every 500 operating hours per Endecotts Technical Bulletin TB-SD-02.
Is the unit compatible with ISO/IEC 17025 accreditation requirements?
Yes—when operated with documented procedures, calibrated sieves, and traceable verification records, it satisfies clause 6.4.10 (Equipment Verification) and 7.7 (Sampling) of ISO/IEC 17025:2017.
