NEXOPART EML 200 Premium Remote Sieve Analyzer (formerly Haver & Boecker)

Overview

The NEXOPART EML 200 Premium Remote Sieve Analyzer is a high-precision, electromagnetically driven laboratory sieve shaker engineered for reproducible dry and wet particle size distribution analysis in accordance with international standards including ISO 2591-1, ISO 9276-2, ASTM E11, and USP . Developed by NEXOPART — the dedicated successor entity consolidating the former particle characterization divisions of Haver & Boecker oHG and Hosokawa Alpine AG — this instrument delivers German-engineered robustness and metrological traceability. Its core operating principle relies on a controlled three-dimensional sieving motion generated by electromagnetic excitation, enabling uniform energy transfer across the entire sieve stack without mechanical wear or inertia-related bias. Unlike rotary or gyratory shakers, the EML 200’s motion profile ensures optimal particle stratification and penetration through mesh apertures, particularly critical for cohesive, fine, or irregularly shaped powders. The “Remote” configuration integrates a fully independent control unit and IP65-rated wet-sieving components, allowing safe operation in humid environments or during aqueous dispersion protocols — a requirement for pharmaceutical granules, mineral slurries, or ceramic precursors.

Key Features

• Electromagnetic drive system with auto-adjusting amplitude (up to 3 mm), eliminating gearboxes, belts, or eccentric mechanisms that degrade over time
• Dual-mode operation: programmable dry sieving and standardized wet sieving with integrated full-cone spray nozzle and adjustable water flow rate
• Enhanced vibration damping architecture reduces operational noise to ≤65 dB(A), suitable for shared lab environments
• Large backlit LCD display with intuitive menu navigation; real-time visualization of amplitude, elapsed time, and active program ID
• 49 programmable sieve analysis methods stored locally; parameters include duration, interval timing (0–99 s), amplitude setpoint, and wet/dry mode selection
• Dedicated remote control unit with physical keypad and status LEDs — decoupled from main unit for splash protection and ergonomic placement during wet procedures
• “Twinnut” quick-clamp option (order code 205322938 / 205322945) enables tool-free sieve stack assembly/disassembly in <15 seconds
• Transparent front panel allows visual monitoring of particle motion and sieve loading status without interrupting analysis
• Calibration-ready design compliant with ISO 9001 quality management requirements; includes documentation templates for internal audit and traceable verification

Sample Compatibility & Compliance

The EML 200 Premium Remote accommodates a broad range of particulate materials: from free-flowing metal powders (e.g., Ti-6Al-4V, Inconel 718) and pharmaceutical excipients (microcrystalline cellulose, lactose monohydrate) to abrasive mineral ores (quartz, bauxite) and temperature-sensitive polymers. Its 20 µm – 125 mm measurement range covers applications from nanoscale pigment dispersions (via wet sieving with surfactant-stabilized suspensions) to coarse aggregate grading per EN 933-1. All wet sieving operations adhere to ISO 11277 for soil particle size analysis and ASTM C136 for construction aggregates. The instrument’s structural rigidity (37–40 kg net weight, RAL 9003 white powder-coated steel housing) minimizes resonance artifacts during extended runs. Electrical safety complies with IEC 61000-6-3 (EMC) and IEC 61010-1 (lab equipment). CE marking confirms conformity with EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU.

Software & Data Management

Each unit ships with CSA 5.0 Basic software license pre-activated — a validated Windows-based platform supporting automated data acquisition, cumulative undersize/oversize calculation, and graphical presentation of Rosin-Rammler or log-normal distribution curves. Raw time-series amplitude and motor current data are logged at 10 Hz for post-run diagnostics. Export formats include CSV, PDF reports (with customizable headers, lab logos, and analyst signatures), and XML for LIMS integration. Ethernet connectivity enables remote monitoring via TCP/IP, while optional CSA Professional add-ons support 21 CFR Part 11 compliance (electronic signatures, audit trails, role-based access control) and GLP/GMP-aligned reporting workflows. Calibration records, method validation logs, and maintenance history are archived within the software database with immutable timestamps.

Applications

• Quality control of active pharmaceutical ingredients (APIs) and final dosage forms per USP and Ph. Eur. 2.9.32
• Particle size specification verification for battery cathode materials (NMC, LFP) prior to slurry mixing
• Aggregates gradation testing in civil engineering labs per AASHTO T 27 and EN 933-1
• Routine QC of food-grade starches, flour, and powdered dairy products under HACCP frameworks
• Research-scale optimization of milling and classification processes in mineral processing
• Validation of spray-dried ceramic suspensions for tape casting and additive manufacturing feedstocks
• Environmental analysis of sediment fractions in contaminated site remediation studies

FAQ

What distinguishes the “Remote” variant from the standard EML 200 Premium?
The Remote model includes a physically isolated control unit rated IP65, a sealed conical spray nozzle assembly, reinforced waterproof cabling, and firmware-locked wet-mode safeguards — all designed to meet IEC 60529 ingress protection requirements during aqueous sieving.
Can the EML 200 Premium Remote be integrated into an automated lab workflow?
Yes — via its native Ethernet interface and Modbus TCP protocol support, it interfaces directly with PLCs, SCADA systems, or central lab automation platforms without third-party gateways.
Is CSA 5.0 software compatible with Windows 11 and 64-bit architectures?
Yes — CSA 5.0 v5.2.1 and later versions are certified for Windows 10/11 (64-bit), .NET Framework 4.8+, and SQL Server Express 2019+.
How is traceability ensured during ISO 9001 audits?
The instrument provides a factory-issued calibration certificate with uncertainty budget; users may perform in-house verification using certified reference test sieves (e.g., ISO 3310-1 Class F) and document results in the built-in QA log module.
What maintenance is required for long-term performance stability?
No routine lubrication or belt replacement is needed. Annual verification of electromagnetic coil impedance and amplitude linearity — using the included calibration jig and digital displacement sensor — is recommended and supported by NEXOPART service engineers worldwide.
