Overview
The Mayzum MZ-Y300 Pore-Structured Foam & Sponge Density Analyzer is a precision benchtop instrument engineered for the accurate determination of bulk density, apparent density, water absorption, and open/closed cell porosity in highly compressible, low-density porous materials. It operates on Archimedean buoyancy principles—measuring weight in air and submerged weight in distilled water (or alternative wetting liquid)—and applies standardized correction algorithms per ISO 1183-1 and ASTM D3574 to compute true material density while accounting for surface tension, temperature-dependent fluid density, and sample geometry effects. Unlike general-purpose densimeters, the MZ-Y300 integrates a dedicated sample support cradle, hydrophobic coating on immersion fixtures, and programmable dwell-time stabilization to minimize deformation-induced error during submersion—a critical requirement for soft, compressible foams such as PU, EPDM, EVA, and polyethylene-based cellular structures.
Key Features
- Benchtop architecture with integrated high-resolution analytical balance (300 g capacity, 0.001 g readability) and calibrated stainless-steel immersion assembly
- Digital LCD interface with real-time dual-weight display (air weight / submerged weight), automatic density calculation, and unit toggle (g/cm³, kg/m³, lb/ft³)
- Optimized for compliant testing per ASTM D3574 (flexible cellular materials), ISO 845 (cellular plastics – density determination), and ISO 1183-1 (plastics – methods for determining density)
- Configurable measurement mode: single-point density, water absorption (% w/w), and derived open-cell porosity using standardized saturation protocols
- Thermal drift compensation via built-in ambient temperature sensor; supports manual input of water density at measured temperature (20 °C reference standard)
- Robust mechanical design with anti-vibration feet, corrosion-resistant components, and IP20-rated enclosure for controlled laboratory environments
Sample Compatibility & Compliance
The MZ-Y300 accommodates a broad spectrum of low-rigidity, high-porosity solids—including flexible polyurethane (PU) foam, ethylene propylene diene monomer (EPDM) elastomeric sponge, expanded polyethylene (EPE), ethylene-vinyl acetate (EVA) cushioning, rigid polyisocyanurate (PIR) insulation boards, and composite laminates with cellular cores. Samples must be geometrically stable under brief immersion and non-soluble in water. For closed-cell materials, vacuum saturation per ASTM D2842 or ISO 2781 may be performed externally prior to analysis. The instrument supports full traceability documentation required under GLP-compliant workflows, including operator ID logging, timestamped result export (via optional RS232/USB), and audit-ready measurement records aligned with ISO/IEC 17025 calibration frameworks.
Software & Data Management
While the MZ-Y300 operates as a standalone instrument with embedded firmware, it supports ASCII-formatted data output via serial interface for integration into LIMS or QA/QC databases. Exported records include: sample ID, air weight (g), submerged weight (g), water temperature (°C), calculated density (g/cm³), water absorption (%), and pass/fail status against user-defined specification limits. No proprietary software installation is required; raw data streams are compatible with Excel, LabVIEW, and Python-based analysis pipelines. Firmware updates maintain alignment with evolving national standards (e.g., GB/T 6343 revisions) and include enhanced outlier detection logic for repeated measurements.
Applications
This analyzer serves quality control laboratories in automotive seating component manufacturing, athletic footwear R&D, medical cushioning validation, building insulation certification, and packaging material qualification. Typical use cases include: verifying batch-to-batch consistency of molded PU seat foams per OEM specifications; quantifying density gradients across extruded EVA midsole layers; validating open-cell content in acoustic damping felts; assessing long-term compression set impact on thermal insulation density; and supporting failure analysis of delaminated composite sandwich panels. Its repeatability (±0.002 g/cm³ at 95% confidence, n=10) meets internal QC thresholds for Tier-1 suppliers operating under IATF 16949 and ISO 9001 frameworks.
FAQ
What standards does the MZ-Y300 directly support?
ASTM D3574, ISO 845, ISO 1183-1, GB/T 6343, and ISO 2781 (when used with external vacuum saturation equipment).
Can it measure closed-cell content?
Not directly—but when combined with ASTM D2842 vacuum saturation and post-saturation weighing, users can derive closed-cell content using the two-step density method.
Is calibration traceable to national metrology institutes?
Yes—factory calibration uses NIST-traceable weights and certified water density references; users may perform intermediate verification with certified density standards (e.g., Pyrex glass, stainless steel).
