Overview
The FRITSCH Analysette 3 Digital Precision Vibratory Sieve Shaker is an electromagnetically driven, microprocessor-controlled particle size analysis instrument engineered for high-accuracy dry, wet, and micro-fine sieving in accordance with internationally recognized standards. Based on the principle of vertical oscillatory motion generated by a precisely regulated electromagnetic drive unit, the Analysette 3 imparts controlled kinetic energy to stacked analytical sieves—lifting particles vertically and allowing gravitational re-settlement through mesh apertures. This cyclical lift-and-drop mechanism ensures efficient stratification and separation across defined aperture sizes, enabling reproducible quantification of particle size distribution (PSD) in powders, granules, and agglomerates. Designed for integration into quality control laboratories operating under ISO 9001, GLP, and GMP frameworks, the instrument delivers traceable, auditable results compliant with DIN 66165 (repeatability requirements), ISO 3310-1/-2 (sieve specifications), and ASTM E11 (standard specification for wire cloth and sieves). Its rigid cast-aluminum housing, vibration-damped base, and sealed electromagnetic actuator ensure long-term mechanical stability and minimal thermal drift during extended operation.
Key Features
- Digital real-time display of amplitude (in mm) and vibration frequency (in Hz), enabling precise process parameter monitoring and documentation.
- IP65-rated ergonomic stainless-steel membrane keypad with tactile feedback—resistant to dust ingress and water splashes, suitable for industrial laboratory environments.
- Electronic torque-controlled sieve clamping system ensuring uniform, repeatable tension across all sieve diameters (8″, 200 mm, 100 mm, 50 mm, 25 mm), directly fulfilling ISO 9001 calibration traceability requirements for test equipment.
- RS232 serial interface supporting full remote control, automated start/stop, parameter logging, and integration with LIMS or MES platforms.
- Onboard memory for up to nine user-defined sieving programs—including time, amplitude, frequency, and sieve stack configuration—enabling rapid method recall without software dependency.
- Modular sieve tray compatibility: supports up to 10 × 50-mm or 16 × 25-mm sieves per run, accommodating multi-stage PSD analysis in a single cycle.
Sample Compatibility & Compliance
The Analysette 3 accommodates diverse sample types across three operational modes: dry sieving (32 µm – 63 mm), wet sieving (20 µm – 10 mm), and micro-fine sieving (5 µm – 100 µm). Dry sieving is optimized for free-flowing, non-cohesive materials such as cement, sand, ores, and pharmaceutical excipients. Wet sieving employs integrated spray nozzles and drainage ports to suspend electrostatic or cohesive fines (e.g., nanosilica, pigments, metal oxides) in aqueous or solvent-based media, preventing blinding and improving resolution. Micro-fine sieving utilizes specialized ultra-thin stainless-steel meshes with precision-etched apertures and low-mass frames to minimize inertia-related errors at sub-10-µm cut points. All supplied sieves are certified to ISO 3310-1 (metal wire cloth) and ASTM E11, and include EN 10204 3.1B mill test certificates verifying material composition and dimensional conformity.
Software & Data Management
AUTOSIEVE™ software serves as the dedicated data acquisition and analysis module for the Analysette 3. It automates mass recording per sieve tray via connected analytical balances (via RS232 or USB), calculates cumulative and differential PSD curves, and generates standardized reports compliant with ISO 13320 and USP <786>. The software supports audit trail functionality—including operator ID, timestamped parameter changes, and result modifications—with optional 21 CFR Part 11 compliance packages available for regulated pharmaceutical and biotech users. All raw data files are stored in open CSV format for third-party statistical analysis or integration into enterprise data lakes. Calibration logs, maintenance records, and sieve certification documents can be attached to individual test protocols for full traceability.
Applications
The Analysette 3 is routinely deployed in R&D, production QA/QC, and regulatory submission workflows across cement manufacturing (ASTM C109/C184), mineral processing (ISO 8501), food & feed (Codex Alimentarius), ceramics (ISO 13753), and advanced materials (battery cathode powders, catalysts, additive manufacturing feedstocks). Its ability to validate sieve integrity against ISO 9000-certified reference standards makes it indispensable for internal calibration verification and external proficiency testing. In pharmaceutical settings, it supports particle size characterization for blend uniformity assessment, dissolution rate prediction, and final product release testing per ICH Q5A and Q6A guidelines.
FAQ
What standards does the Analysette 3 comply with for sieve calibration and result validation?
It conforms to ISO 3310-1/-2 (sieve specifications), ASTM E11 (sieve classification), DIN 66165 (repeatability requirements), and EN 10204 3.1B (material certification). Optional ISO 9000 traceable calibration kits are available.
Can the instrument perform both dry and wet sieving in the same configuration?
Yes—wet sieving requires installation of the optional wet-sieving kit (spray nozzle, drain hose, splash guard), while dry sieving uses standard sieve stacks. No hardware modification is needed between modes.
Is AUTOSIEVE™ software validated for use in FDA-regulated environments?
AUTOSIEVE™ supports 21 CFR Part 11-compliant configurations when deployed with electronic signatures, audit trails, and role-based access control—subject to site-specific IQ/OQ/PQ validation protocols.
How is sieve tension calibrated and verified?
Tension is applied and monitored electronically via a torque-controlled clamping system; calibration is performed using a certified torque wrench and documented per ISO/IEC 17025 requirements.
What is the maximum allowable sample mass for micro-fine sieving?
For optimal resolution in the 5–100 µm range, recommended sample mass is 0.2–0.5 g—exceeding this may cause mesh clogging or inaccurate mass recovery due to static adhesion effects.
