Environmental stress cracking testing machine/ ESCR Test Machine / Polymer Stress Cracking Resistance Tester

Standard

  • ASTM D1693: Exclusively designed for bending beam and constant load tests on polyethylene and other thermoplastics.
  • ISO 22088-3: Configurable for notched specimen testing in aggressive media.

Product Advantages

1. Unmatched Throughput

  • 460-Sample Capacity: Test up to 460 specimens simultaneously (46 vessels × 10 samples/vessel).
  • High-Efficiency Design: 40% faster batch testing than competitive models.

2. Precision Engineering

  • Uniform Stress Application: Compliant with ASTM D1693’s 2.75mm bending beam specification.
  • PID Temperature Control: ±0.2°C stability across -10°C to 100°C range.

3. User-Centric Workflow

  • Smart Sample Prep: ASTM-compliant milling tools and prefabricated specimen jigs included.
  • Intuitive Touchscreen: Pre-loaded ASTM protocols with adjustable hold times (1–1,000 hours).

4. Safety & Compliance

  • Chemical-Resistant Construction: 316L stainless steel bath and PTFE-coated components.
  • Audit-Ready Reporting: 21 CFR Part 11 compliant data logging with electronic signatures.

5. Adaptive Testing

  • Solvent Versatility: Compatible with surfactants (soap), hydrocarbons (oils), and polar solvents (alcohols).

Product Features

  • Modular Bath System:
    • 46-position carousel with quick-release glass vessels (250mL capacity).
    • Dual-circuit heating for rapid temperature equilibration.
  • Stress Loading System:
    • Manual or motorized bending fixtures with 0–50N load range.
    • Laser-aligned specimen grips for consistent strain distribution.
  • Chemical Management:
    • Integrated solvent level sensors with low-volume alerts.
    • Vented enclosure for fume extraction (compatible with external HVA systems).
  • Data Integrity:
    • 100Hz sampling rate captures crack initiation events.
    • Wireless data export via Wi-Fi/Bluetooth to LIMS platforms.
  • Safety Suite:
    • Leak-proof magnetic drive stirrers.
    • Emergency solvent dump system with CO₂ fire suppression.
