NEXOPART EML 200 Premium Electromagnetic Sieve Shaker

Overview

The NEXOPART EML 200 Premium Electromagnetic Sieve Shaker is a high-precision, laboratory-grade dry and wet sieving instrument engineered for reproducible particle size distribution (PSD) analysis in quality control, R&D, and regulatory-compliant environments. Developed by NEXOPART — the dedicated particle analysis entity formed from the strategic integration of Haver & Boecker oHG’s sieve technology and Hosokawa Alpine AG’s air jet sieving expertise — the EML 200 series represents the evolution of German mechanical engineering applied to standardized sieve analysis. Unlike mechanical or rotary shakers, the EML 200 Premium employs electromagnetic drive technology to generate a precisely controlled three-dimensional sieving motion. This motion combines vertical lift, horizontal oscillation, and rotational components, ensuring uniform particle stratification and optimal particle passage through mesh apertures across the entire sieve surface. The system’s automatic amplitude modulation adapts dynamically to sample mass and density, minimizing over-grinding, blinding, or segregation artifacts — critical for compliant PSD reporting under ASTM E11, ISO 3310-1, and USP .

Key Features

• Electromagnetic drive with auto-adjusting amplitude (up to 3 mm), eliminating mechanical wear and enabling consistent energy input regardless of load variation.
• Large backlit LCD touchscreen interface with intuitive navigation, real-time parameter feedback, and multilingual UI support (English, German, French, Spanish).
• 49 programmable sieving methods stored onboard — including time, amplitude, interval timing (0–99 s), and run mode (interval or continuous) — enabling rapid method recall and operator-independent execution.
• Optional TwinNut quick-lock sieve clamping system reduces setup time by >60% versus standard clamps and ensures repeatable axial force distribution across all sieve diameters (50–203 mm).
• Integrated Ethernet port supports direct connection to LIMS or lab networks; enables remote monitoring, firmware updates, and secure data export via TCP/IP.
• Enhanced acoustic damping architecture reduces operational noise to <62 dB(A) at 1 m — suitable for open-plan laboratories and GLP-compliant facilities requiring low ambient disturbance.
• Compliant with ISO 9001 traceability requirements: includes documented calibration verification procedure and certified reference test sieves (available separately).

Sample Compatibility & Compliance

The EML 200 Premium accommodates a broad spectrum of particulate materials — including pharmaceutical granules, metal powders, catalysts, food ingredients, ceramics, and construction aggregates — across a validated range of 20 µm to 125 mm. Its dual-mode capability supports both dry sieving (standard for free-flowing powders) and wet sieving (for cohesive, hygroscopic, or ultrafine fractions prone to agglomeration). The instrument accepts standard ISO/ASTM-compliant test sieves with wire diameters from 20 µm upward and frame heights up to 32 mm (15-sieve stack) or 50 mm (9-sieve stack). All mechanical interfaces are designed to meet DIN EN ISO 2591-1 dimensional tolerances, ensuring interchangeability with legacy Haver & Boecker and Alpine sieve sets. Full compliance documentation — including Declaration of Conformity (CE), EMC Directive 2014/30/EU, and Low Voltage Directive 2014/35/EU — is supplied with each unit.

Software & Data Management

Each EML 200 Premium ships with a pre-activated CSA 5.0 Basic software license — a Windows-based evaluation platform developed by NEXOPART for post-sieving data visualization, cumulative/differential curve generation, D10/D50/D90 calculation, and statistical comparison against reference standards. The software supports automated report generation in PDF or Excel format, with embedded metadata (operator ID, timestamp, method ID, sieve lot numbers). When connected via Ethernet, the shaker logs full audit trails — including start/stop times, amplitude profiles, and error flags — satisfying FDA 21 CFR Part 11 requirements for electronic records when paired with validated user access controls and digital signatures. Optional CSA Pro modules enable advanced features such as multi-sample batch processing, SPC charting, and integration with MES/QMS platforms via OPC UA.

Applications

• Pharmaceutical solid dosage development: granule and excipient PSD verification per USP and ICH Q5A.
• Advanced battery material QC: cathode/anode powder classification prior to slurry mixing.
• Food safety & texture control: flour, sugar, and spice particle consistency testing aligned with Codex Alimentarius standards.
• Metallurgical powder certification: ISO 4497-compliant analysis for additive manufacturing feedstocks.
• Environmental sediment characterization: ASTM D422 soil gradation using wet-sieving protocol.
• Regulatory submission support: generation of GMP-aligned raw data packages for EMA/FDA dossier submissions.

FAQ

Does the EML 200 Premium support wet sieving?
Yes — unlike the Pure variant, the Premium model includes a sealed base plate, corrosion-resistant stainless-steel housing, and optional water drainage kit for validated wet sieving per ISO 2591-2.
Can I use existing Haver & Boecker sieves with this instrument?
Yes — all standard Haver & Boecker test sieves (50–203 mm diameter, ISO 3310-1 or ASTM E11 specifications) are fully compatible without adapters.
Is calibration traceable to national standards?
Yes — NEXOPART provides a documented calibration verification procedure and offers NIST-traceable certified reference sieves (CRS) for periodic performance checks per ISO 9001 clause 7.1.5.
What is the maximum number of sieves supported in a single run?
Up to 15 sieves (32 mm effective height) or 9 sieves (50 mm effective height), depending on sample volume and desired resolution.
How is data integrity ensured for regulated environments?
Through built-in audit trail logging, electronic signature support in CSA Pro, and alignment with ALCOA+ principles — including attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available data handling.
