Bonded Septa Pull-off Force Testing: Scientific Validation System for Lab Consumables Reliability

Core Components of the Validation System

Aligned with ISO 965 metric thread tolerances and GOST-R certification, our protocol covers:

• Static mechanics: 50.7 N average pull-off force (20 % above industry).
• Environmental stress: > 98 % seal retention after –80 °C/60 °C aging.
• Failure mode library: 7 categories with microscopic deformation imagery.

 Pull-off Force Test Methodology

1. Sample Prep: Ultrasonic cleaning, then 24 h at 23 °C/50 % RH.
2. Precision Assembly: ≥ 95 % contact area via surface scanning.
3. Mechanical Loading: 30 mm/min per GB/T 2828-2018, recording force-displacement.
4. Failure Analysis: High-speed imaging to classify interfacial vs. material failures.
