MingShen Science CY/TF Long-Handle Sampling Shovel

Overview

The MingShen Science CY/TF Long-Handle Sampling Shovel is a purpose-engineered field and laboratory tool designed for representative solid bulk material sampling—particularly in coal preparation, mineral processing, environmental monitoring, and industrial quality control workflows. Constructed from corrosion-resistant stainless steel (standard 201; optional 304 grade for enhanced chemical and chloride resistance), the CY/TF series adheres to fundamental principles of statistical sampling integrity: consistent scoop geometry, controlled insertion depth, and ergonomic leverage to minimize operator fatigue during repetitive, high-volume sampling tasks. Its extended handle design enables safe, contamination-free sampling from deep bins, conveyor belts, stockpiles, or railcar compartments without requiring personnel to enter confined or elevated zones. The three model variants (CY/TF1, CY/TF2, CY/TF3) are dimensionally optimized to match standard coal particle size classifications defined in ISO 13909-1, ASTM D2234, and GB/T 475—ensuring compatibility with prescribed sampling protocols including the nine-point method for primary increment collection.

Key Features

• Three standardized configurations (CY/TF1–TF3) calibrated to maximum particle sizes of 25 mm, 50 mm, and 100 mm respectively—aligned with international coal sampling granularity tiers.
• Stainless steel construction (201 SS as standard; 304 SS available on request) provides mechanical durability, non-reactivity with organic and inorganic matrices, and compliance with food-grade and pharmaceutical-grade hygiene prerequisites where applicable.
• Ergonomically proportioned handle lengths (710–830 mm) reduce spinal loading during horizontal scooping and vertical lifting, supporting occupational safety standards per ISO 2631-1 (hand-arm vibration) and OSHA 3151 guidelines.
• Flat, rigid scoop profile with precisely formed edges ensures clean, non-compacting material transfer—critical for preserving sample homogeneity prior to downstream size reduction and division.
• Non-porous surface finish facilitates rapid decontamination between sampling events, meeting cross-contamination prevention requirements outlined in ISO/IEC 17025:2017 Clause 7.4.1.

Sample Compatibility & Compliance

The CY/TF shovel is validated for use across heterogeneous granular solids including bituminous and anthracite coal, lignite, coke, limestone, fly ash, biomass pellets, and industrial aggregates. Its dimensional specifications conform to the physical constraints required by statutory coal sampling methods: GB/T 475 (Chinese National Standard), ISO 13909-1 (Hard Coal and Coke—Sampling—Part 1: General Principles), and ASTM D2234/D7508 (Standard Practice for Collection of Gross Samples of Coal). When deployed within a documented sampling plan—including stratified random selection, nine-point grid placement, and incremental mass calculation—the tool contributes directly to achieving the minimum mass requirements specified in ISO 13909-2 (sub-sampling precision) and supports traceability under GLP and ISO/IEC 17025 quality management systems.

Software & Data Management

As a passive mechanical sampling instrument, the CY/TF shovel does not incorporate embedded electronics or firmware. However, it integrates seamlessly into digital sampling workflows via companion documentation tools: LIMS platforms (e.g., Thermo Fisher SampleManager, LabVantage), electronic lab notebooks (ELNs), and paperless SOP execution systems. Each shovel can be assigned a unique asset ID and logged within calibration and maintenance records. While no firmware updates or data export functions apply, its use is auditable through metadata capture—including operator ID, timestamp, location tag (via GPS-enabled mobile SOP apps), and associated batch/lot numbers—supporting full compliance with FDA 21 CFR Part 11 (electronic signatures) and EU Annex 11 (computerized system validation) when used in regulated environments.

Applications

• Primary coal sampling from conveyor belts, railcars, barges, and stockpiles per ISO 13909 and GB/T 475.
• Preparation of reference samples for calorific value, proximate analysis (moisture, ash, volatile matter, fixed carbon), and ultimate analysis (C, H, N, S, O).
• Environmental site assessment: soil and sediment core splitting, waste characterization, and landfill leachate solid-phase sampling.
• Quality assurance in cement raw meal homogenization, ore blending, and feedstock verification prior to thermal processing.
• Academic and research laboratories conducting particulate flow behavior studies, segregation analysis, or bulk density calibration.

FAQ

Is the CY/TF shovel suitable for hazardous or explosive atmospheres?
No electrical components are present; however, static dissipation must be verified independently if used in ATEX/IECEx Zone 21 or 22 environments. Conductive handle coatings or grounding straps may be added per site-specific risk assessment.

Can the shovel be sterilized for microbiological sampling?
Yes—autoclaving at 121°C for 20 minutes is compatible with both 201 and 304 stainless steel variants. Surface passivation post-sterilization is recommended to restore oxide layer integrity.

What is the recommended cleaning protocol between samples?
Rinse with deionized water, followed by ethanol wipe-down and air-drying. For organic residue removal, use mild alkaline detergent (pH 9–10); avoid chloride-based cleaners to prevent pitting corrosion.

Does MingShen Science provide calibration certificates or metrological traceability?
Dimensional verification reports (scoop width, depth, handle length) are available upon request. As a mechanical sampling tool, formal calibration per ISO/IEC 17025 is not applicable—but dimensional conformity testing supports GMP/GLP audit readiness.
