Siebtechnik LAVIB300 Horizontal Vibration Sieve Analyzer

Overview

The Siebtechnik LAVIB300 Horizontal Vibration Sieve Analyzer is a precision-engineered laboratory instrument designed for standardized dry and wet sieving of free-flowing, dispersible materials. Based on the principle of horizontal circular vibration—where sample material is subjected to controlled orbital motion in a horizontal plane—the LAVIB300 ensures uniform particle distribution across the sieve surface and minimizes particle stratification or blinding. This mechanical separation method complies with internationally recognized test standards including DIN ISO 2591-1 (determination of particle size distribution by sieving), ISO 9276-1 (representation of particle size distributions), and ASTM E11 (specification for wire cloth and sieves for testing purposes). The system is widely deployed in QC laboratories, R&D departments, and production facilities across pharmaceuticals, chemicals, food, minerals, and advanced ceramics industries where reproducible, traceable granulometric data are required for batch release, formulation development, or raw material qualification.

Key Features

• Horizontal circular vibration drive delivering consistent 270 min⁻¹ (4.5 Hz) oscillation at fixed amplitude—ensuring high repeatability independent of mains supply frequency (50 Hz certified)
• Digital control interface enabling precise setting and real-time monitoring of sieving duration (1–99 min), amplitude level, rotational direction (clockwise/counter-clockwise), and motor speed
• Modular sieve stack configuration supporting up to 8 sieve levels with interchangeable diameters: 100 mm, 150 mm, 200 mm, 203 mm, and 305 mm—optimized for both small-batch screening and high-mass analysis (up to 6 kg per run)
• Patented anti-clogging sieve edge sealing and laser-etched calibration markings on all sieve frames—guaranteeing metrological integrity and compliance with ISO/IEC 17025 documentation requirements
• Low-noise operation (<65 dB(A)) achieved through balanced mass inertia and vibration-damped housing—suitable for shared laboratory environments without acoustic isolation
• Tool-free, quick-lock sieve clamping mechanism (rotary knob or bayonet-style) enabling rapid setup changes and minimizing operator-induced variability

Sample Compatibility & Compliance

The LAVIB300 accommodates a broad spectrum of particulate systems: dry powders (e.g., lactose, catalysts, metal alloys), granules, friable agglomerates, and aqueous or organic suspensions (when equipped with wet-sieving accessories). Its 20 µm–40 mm dynamic range covers fine pharmaceutical actives, coarse mineral aggregates, and engineered composites. All sieve meshes meet ASTM E11 tolerance classes for woven wire cloth, while frame construction adheres to DIN EN ISO 3310-1 dimensional specifications. The instrument supports GLP-compliant workflows via optional audit-trail-enabled software integration and satisfies prerequisites for FDA 21 CFR Part 11 when paired with validated PC-based control modules.

Software & Data Management

While the base LAVIB300 operates via standalone digital panel control, it is fully compatible with Siebtechnik’s optional SieveSoft™ PC software suite. This Windows-based application enables automated method storage, real-time weight tracking (when interfaced with analytical balances), statistical reporting (D10/D50/D90, % retained, cumulative undersize), and export to CSV, PDF, or LIMS-compatible XML formats. All data logs include timestamped metadata—operator ID, sieve set ID, environmental conditions (optional sensor input), and calibration status—supporting full traceability under ISO/IEC 17025 and GMP Annex 11 requirements.

Applications

• Pharmaceutical: Excipient particle size verification per USP , blend uniformity assessment, and inhaler formulation aerodynamic cut-off validation
• Chemicals: Catalyst support grading, pigment dispersion quality control, and polymer pellet sizing prior to extrusion
• Food & Feed: Flour granulation profiling, spice particle consistency checks, and premix homogeneity verification
• Minerals & Construction: Sand gradation analysis (ASTM C136), crushed aggregate classification (EN 933-1), and slag particle distribution mapping
• Advanced Materials: Battery cathode/anode powder classification, additive manufacturing feedstock screening (per ASTM F3049), and ceramic green-body particle packing optimization

FAQ

What sieve diameters are supported by the LAVIB300?
The instrument accepts standard sieve diameters of 100 mm, 150 mm, 200 mm, 203 mm, and 305 mm—each compatible with ISO 3310-1 and ASTM E11 mesh specifications.
Can the LAVIB300 perform wet sieving?
Yes—when fitted with optional liquid-tight sieve frames, splash guards, and drain trays, the LAVIB300 supports standardized wet sieving per ISO 2591-2 and ASTM C136/C702 protocols.
Is calibration documentation provided with each sieve set?
Each laser-marked sieve includes a manufacturer’s certificate of conformity referencing DIN ISO/IEC 17025-accredited calibration, traceable to national standards (e.g., PTB, NIST).
How is measurement reproducibility ensured across different laboratories?
By maintaining strict adherence to horizontal vibration kinematics (amplitude ±0.1 mm, frequency ±0.05 Hz), standardized sieve mounting torque, and ambient temperature/humidity monitoring—procedures codified in ISO 2591-1 Annex A.
Does the LAVIB300 meet regulatory requirements for pharmaceutical QC?
When operated with validated methods, calibrated sieves, and documented maintenance records, the system fulfills ICH Q5A and EU GMP Annex 18 expectations for physical characterization of solid dosage forms.
