Drick DRK-QS40 Multi-Function Laboratory Vibratory Sieve for Solids, Powders, Slurries and Pastes

Overview

The Drick DRK-QS40 is a precision-engineered laboratory vibratory sieve system designed for quantitative particle size distribution analysis of dry powders, granular solids, wet slurries, and semi-fluid pastes. It operates on the principle of mechanical vibration-driven sieving—utilizing controlled elliptical motion generated by an electromagnetic or eccentric motor drive to ensure uniform material dispersion across stacked sieve decks. Unlike static or hand-shaken sieves, the DRK-QS40 delivers reproducible, operator-independent results compliant with standardized sieve analysis methodologies including ISO 9276-1, ASTM E11, and USP <786>. Its modular design accommodates up to five nested sieve frames (standard 200 mm diameter), enabling multi-stage fractionation in a single run. The unit is calibrated to maintain consistent amplitude and frequency across load variations, minimizing segregation bias and ensuring high inter-laboratory repeatability.

Key Features

• Adjustable vibration intensity (amplitude range: 0.5–3.0 mm) and frequency (100–300 rpm), digitally controlled via integrated microprocessor
• Stainless steel construction (304 grade) for corrosion resistance and GMP-compliant cleanability
• Quick-lock sieve frame mechanism enabling tool-free assembly/disassembly within 15 seconds per deck
• Integrated timer (1 s–99 min) with automatic shut-off and audible end-of-cycle alert
• Optional vacuum-assisted dust containment hood (ISO 14644-1 Class 8 compatible) for hazardous or hygroscopic materials
• Load capacity up to 500 g per sieve deck, validated for representative sampling per ISO 13320 guidelines

Sample Compatibility & Compliance

The DRK-QS40 supports diverse sample matrices without modification: free-flowing pharmaceutical excipients (e.g., lactose, microcrystalline cellulose), mineral ores, ceramic precursors, food-grade starches, battery cathode slurries (aqueous/non-aqueous), and polymer masterbatches. All contact surfaces meet FDA 21 CFR §177.2600 requirements for indirect food contact. The system complies with CE Machinery Directive 2006/42/EC (with Declaration of Conformity available upon request) and conforms to IEC 61000-6-2/6-4 for electromagnetic compatibility. Routine operation satisfies GLP documentation requirements when paired with optional audit-trail-enabled software (see Software & Data Management).

Software & Data Management

When equipped with the optional Drick SieveLog Pro v3.2 software (Windows 10/11 compatible), the DRK-QS40 enables full digital workflow integration: automated test method recall, real-time sieve residue mass logging, cumulative undersize/oversize distribution plots, and export to CSV/PDF/Excel formats. The software includes 21 CFR Part 11-compliant user access controls (role-based permissions), electronic signatures, and immutable audit trails for all parameter changes and result exports—essential for regulated QC environments in pharmaceuticals, cosmetics, and advanced materials R&D. Raw data files are stored in encrypted SQLite format with SHA-256 checksum verification.

Applications

• Pharmaceutical: Granule size screening prior to tablet compression; API particle distribution verification per USP <786>
• Materials Science: Classification of metal powders for additive manufacturing feedstock qualification (ASTM F3049)
• Food & Beverage: Flour and spice particle homogeneity assessment per AACC Method 28-10A
• Battery Manufacturing: Cathode/anode slurry filtration validation before coating process transfer
• Geotechnical Labs: Soil grain-size analysis (ASTM D422, AASHTO T 88) using wet-sieving protocols
• Quality Control: In-process verification of milling efficiency and classifier performance in continuous production lines

FAQ

Is the DRK-QS40 suitable for wet sieving applications?
Yes—equipped with optional silicone-sealed sieve frames and corrosion-resistant stainless steel mesh (316L available), it supports both dry and wet sieving per ISO 2591-1 protocols.
Can sieve mesh sizes be customized beyond standard ASTM E11 ranges?
Yes—custom meshes from 20 µm to 3.35 mm (including ISO 565 and DIN 4188 specifications) are available upon request with NIST-traceable calibration certificates.
Does the system support IQ/OQ/PQ validation documentation?
Yes—Drick provides a complete validation package (IQ/OQ templates, calibration records, and performance qualification test protocols) aligned with ISO/IEC 17025 and Annex 11 requirements.
What maintenance intervals are recommended for long-term reliability?
Vibration motor lubrication every 1,000 operating hours; annual recalibration of amplitude/frequency sensors by authorized service center.
Is remote diagnostics supported?
Yes—the optional Ethernet/Wi-Fi module enables secure remote firmware updates and diagnostic log retrieval via TLS 1.2 encrypted connection.
