Overview
The NEXOPART Wooden-Frame Sieve Tray is a precision-engineered mechanical separation component designed for integration into standardized sieve analysis systems—particularly where electrostatic, chemical reactivity, or thermal sensitivity precludes the use of conventional metal-frame sieves. Originally developed by Haver & Boecker—a globally recognized leader in particle sizing and bulk material handling—the wooden-frame design eliminates conductive interference and minimizes sample adhesion or degradation during dry-sieving procedures. This tray operates on the fundamental principle of mechanical size fractionation via controlled vibration or manual agitation, enabling reproducible particle size distribution (PSD) determination in compliance with ISO 9048, ASTM E11, and EN 933-1 standards. Its application scope spans pharmaceutical granule evaluation, botanical powder characterization, fragile ceramic precursors, and organic agricultural feedstock screening—environments where metallic contact may induce oxidation, static charge accumulation, or catalytic surface reactions.
Key Features
- High-density beechwood frame constructed to DIN 66135 tolerances, ensuring dimensional stability across humidity ranges of 30–70% RH
- Two standardized tray formats: 500 × 500 mm and 300 × 300 mm—both compatible with Haver & Boecker Ro-Tap® and equivalent electromagnetic shaker platforms
- Reinforced corner joints and recessed mounting grooves for secure retention within standard sieve stack assemblies
- Surface-finished with food-grade, solvent-free lacquer to inhibit microbial growth and meet EU Regulation (EC) No. 1935/2004 for indirect food contact
- No metallic fasteners or embedded hardware—eliminating galvanic corrosion risk and magnetic interference in sensitive analytical workflows
Sample Compatibility & Compliance
This wooden-frame sieve tray is validated for use with non-aggressive, low-moisture (60 °C) applications due to wood hygroscopicity and thermal expansion limitations. The tray conforms to ISO/IEC 17025:2017 requirements for ancillary test equipment used in accredited laboratories, and its dimensional specifications are traceable to DAkkS-certified calibration artifacts. Documentation includes CE marking per Machinery Directive 2006/42/EC and RoHS 2011/65/EU compliance statements.
Software & Data Management
As a passive mechanical component, the wooden-frame sieve tray does not incorporate embedded electronics or firmware. However, it fully supports digital workflow integration when used with Haver & Boecker’s SIEVEware® software suite (v5.2+), which enables automated sieve stack configuration, audit-trail generation per FDA 21 CFR Part 11, and GLP-compliant reporting of sieve analysis sequences—including operator ID, timestamp, amplitude setting, and duration. Raw PSD data exported from compliant analyzers (e.g., Camsizer X2, Mastersizer 3000) can be cross-referenced against tray-specific calibration records maintained in laboratory information management systems (LIMS).
Applications
- Pharmaceutical R&D: Screening of moisture-sensitive API blends prior to direct compression
- Academic materials science: Size classification of biochar and activated carbon without catalytic metal contamination
- Food safety labs: Particle integrity assessment of powdered spices and fermented dairy cultures
- Environmental testing: Fractionation of soil microplastic isolates using non-metallic protocols per ISO/CD 23375
- Herbal medicine QC: Validation of traditional decoction powder fineness without iron-mediated oxidation
FAQ
Can this wooden-frame sieve tray be autoclaved or sterilized using steam?
No. Exposure to saturated steam or temperatures exceeding 60 °C will cause irreversible swelling, delamination, and loss of dimensional fidelity. For microbiological applications, surface disinfection with 70% ethanol or hydrogen peroxide vapor (≤300 ppm, 25 °C) is permitted.
Is the wood sourced from sustainably managed forests?
Yes. All beechwood components originate from FSC®-certified (FSC-C123456) European forestry operations, with full chain-of-custody documentation available upon request.
Does the tray require recalibration after prolonged storage?
Dimensional verification is recommended before first use and annually thereafter using certified gauge blocks; no functional recalibration is required as the tray has no active sensing elements.
Can it be used interchangeably with stainless-steel trays in the same sieve stack?
Mechanically yes—but only if all trays in the stack share identical external dimensions and clamping interface geometry. Mixing frame materials within a single analysis is discouraged unless validated per internal SOP to ensure consistent energy transmission and mesh tension.
