Overview
The ZY/TF27 Stainless Steel Coal Sample Container is an engineered laboratory and field sampling solution designed for the secure, contamination-free handling, transport, and temporary storage of coal and coke samples in accordance with international coal testing standards—including ISO 18283:2015 (Solid mineral fuels — Manual sampling), ASTM D2234/D2234M (Standard Practice for Collection of a Gross Sample of Coal), and GB/T 475–2008 (Method for manual sampling of commercial coal in China). Constructed entirely from high-grade 304 stainless steel, the container eliminates rust, chemical leaching, and particulate shedding—critical requirements when preserving sample integrity during multi-stage size reduction, moisture determination, and proximate/ultimate analysis workflows. Its rigid, seamless body and precision-machined lid with silicone gasket ensure dust-tight and moisture-resistant sealing, minimizing ambient exposure during transit or interim storage between preparation steps.
Key Features
- Full-body 304 stainless steel construction—resistant to corrosion, abrasion, and thermal cycling across laboratory and mine-site environments
- Integrated heavy-duty latch-and-hinge lid system with compression seal gasket for repeatable, leak-resistant closure
- Optimized internal volume of 43 L, supporting bulk handling of primary coal lots (≥40 kg) as required by standard preparation protocols
- Dual-format compatibility: accommodates both upright storage of coarse material (≤60 mm) and flat placement of standardized sample trays (600 mm × 600 mm × 50 mm)
- Smooth, non-porous interior surface—facilitates complete sample recovery and simplifies cleaning between batches under GLP-compliant hygiene practices
- Stackable design with reinforced base corners—enables stable, space-efficient storage in sample preparation rooms or mobile lab vehicles
Sample Compatibility & Compliance
The ZY/TF27 container is validated for use throughout the full coal sample preparation chain—from gross sampling and stage-wise crushing (60 mm → 13 mm → 6 mm → 3 mm → 1 mm → ≤0.2 mm) to sub-sampling for moisture, ash, volatile matter, sulfur, and calorific value determination. Its dimensions align with the tray specifications referenced in ISO 13909-2 (Coal and coke — Mechanical sampling — Part 2: Sampling of coal — Methodology) for manual secondary division. The container meets material safety requirements outlined in ISO/IEC 17025:2017 (General requirements for the competence of testing and calibration laboratories) for sample containment systems, and supports traceability workflows compliant with GLP and ISO 9001 quality management frameworks.
Software & Data Management
While the ZY/TF27 is a passive physical containment device with no embedded electronics, it integrates seamlessly into digital sample lifecycle management systems. Each unit can be assigned a unique asset ID (e.g., barcode or RFID tag) for linkage to LIMS platforms such as Thermo Fisher SampleManager, LabVantage, or custom ERP modules. When used in conjunction with certified weighing stations and automated sample dividers, the container’s consistent geometry and mass stability support reproducible gravimetric tracking across preparation stages—enabling audit-ready records for FDA 21 CFR Part 11–aligned environments where electronic signatures and data integrity are mandated.
Applications
- Primary field collection and transport of run-of-mine (ROM) coal and coke feedstock
- Intermediate storage during standardized size-reduction sequences per ASTM D3173, D3174, D3175, and D3176
- Holding containers for moisture equilibrium conditioning (e.g., 40 °C drying ovens prior to total moisture determination)
- Secure transfer of analytical sub-samples (e.g., 40 g ≤0.2 mm fractions) to elemental analyzers or XRF spectrometers
- Reference sample archiving—long-term retention of certified reference materials (CRMs) or inter-laboratory comparison samples
- Use in accredited coal testing laboratories operating under CNAS, UKAS, or A2LA accreditation scopes
FAQ
Is the ZY/TF27 suitable for storing wet or high-moisture coal samples?
Yes—the stainless steel body and gasketed lid provide effective barrier protection against condensation and external humidity ingress; however, prolonged storage of uncured wet samples is not recommended without periodic venting to prevent anaerobic degradation.
Can this container be autoclaved or cleaned in industrial ultrasonic baths?
Yes—304 stainless steel is fully compatible with steam sterilization (up to 134 °C) and aqueous ultrasonic cleaning using neutral pH detergents; avoid chloride-based solvents to prevent pitting corrosion.
Does the container comply with explosion-proof requirements for underground mine use?
No—it is not intrinsically safe or ATEX-certified; it is intended for surface-level sampling, preparation labs, and above-ground transport only.
What documentation accompanies each unit for quality assurance purposes?
Each shipment includes a Certificate of Conformance stating material grade (ASTM A240/A240M Type 304), dimensional verification report, and surface finish specification (Ra ≤ 0.8 µm); optional mill test reports available upon request.
