Overview
The Labthink CYZ-6S Adhesion Tester is a precision-engineered instrument designed to quantify the holding power (creep resistance) of pressure-sensitive adhesives under sustained static load. It operates on the principle of vertical shear creep testing: a standardized test specimen—comprising adhesive-coated substrate bonded to a conditioned stainless steel test plate—is mounted vertically and subjected to a defined gravitational load via calibrated weights. The instrument measures either the displacement of the specimen over time or the elapsed time until complete detachment, providing objective, reproducible metrics for long-term adhesive performance. This methodology aligns with fundamental rheological concepts of viscoelastic creep behavior in polymer-based adhesives and is widely accepted in quality control laboratories across medical device manufacturing, packaging validation, and industrial tape production.
Key Features
- Six independent test stations enable concurrent evaluation of multiple samples—significantly improving throughput without compromising inter-test consistency.
- Microprocessor-controlled timing system with automatic start/stop and data locking functionality ensures traceable, operator-independent measurement sequences.
- Standardized test hardware—including ISO/ASTM-compliant 2000 g ±50 g roller for specimen conditioning and 1000 g ±10 g loading mass (inclusive of loading plate)—guarantees metrological traceability to international reference methods.
- Intuitive PVC membrane keypad interface paired with backlit LCD display simplifies parameter entry, real-time monitoring, and result readout—even in controlled-environment laboratory settings.
- Robust mechanical architecture features corrosion-resistant test frame, precision-machined aluminum mounting rails, and vibration-dampened base—optimized for stable operation during extended-duration tests (up to 10,000 hours).
Sample Compatibility & Compliance
The CYZ-6S supports a broad range of pressure-sensitive adhesive products, including medical transdermal patches, surgical tapes, labeling films, protective masking films, and laminated sealants used in wet-wipe packaging. Its design conforms to the geometric and procedural requirements specified in GB/T 4851 (China), ASTM D3654 (United States), and JIS Z0237 (Japan). All test plates are manufactured to exact dimensional tolerances (60 mm × 40 mm × 1.5 mm) using 304 stainless steel per ASTM E18, ensuring surface energy consistency and minimizing inter-laboratory variability. The instrument’s mechanical configuration satisfies GLP documentation prerequisites, supporting audit-ready records when integrated with external data logging systems.
Software & Data Management
While the CYZ-6S operates as a standalone benchtop unit with embedded firmware, its timing and event-trigger outputs are compatible with third-party data acquisition platforms via RS-232 or optional USB-to-serial interface. Users may export timestamped detachment events—including displacement thresholds or failure times—to CSV or Excel formats for statistical process control (SPC) analysis. When deployed in regulated environments (e.g., ISO 13485-certified medical device facilities), the instrument supports 21 CFR Part 11-compliant workflows through integration with validated LIMS or ELN systems that enforce electronic signatures, audit trails, and user access controls.
Applications
- Validation of peel strength retention in sterile barrier packaging seals for pre-moistened wipe pouches under accelerated aging conditions.
- Comparative assessment of acrylic vs. silicone-based adhesives in wearable biosensor patches exposed to thermal cycling and humidity gradients.
- Batch release testing of industrial transfer tapes used in automotive interior bonding, where long-term shear stability directly impacts field reliability.
- Stability studies supporting shelf-life claims for OTC topical drug patches, per ICH Q5C guidelines on product consistency over time.
- Root cause analysis of delamination failures in multi-layer label constructions subjected to warehouse storage conditions.
FAQ
What standards does the CYZ-6S explicitly support?
It meets the mechanical and procedural specifications of GB/T 4851, ASTM D3654, and JIS Z0237 for holding power testing.
Can the instrument accommodate non-standard test loads?
Yes—custom weight sets (e.g., 500 g, 2000 g) can be installed following recalibration and documented deviation approval per internal SOPs.
Is temperature or humidity control integrated into the system?
No—the CYZ-6S is a mechanically focused tester; environmental conditioning must be performed externally using climate-controlled chambers prior to specimen mounting.
How is calibration verified?
Annual verification against NIST-traceable mass standards and stopwatch calibration is recommended; Labthink provides calibration certificates upon request.
Does the unit support automated data export to enterprise systems?
Direct export requires optional serial communication module and middleware configuration—full 21 CFR Part 11 compliance depends on end-user IT infrastructure validation.
