Partnernship Study: Material Optimization

Designing sample probes for biological analysis presents a unique challenge: achieving high mechanical precision and rigidity while maintaining full compatibility with sensitive biological fluids. Traditional materials often force trade-offs between tight tolerances, structural stability, and clean, inert flow paths—compromising performance and reliability.

IDEX Health & Science addresses this challenge with engineered composite probe assemblies that integrate the best properties of metal and thermoplastics into a single, high-performance solution. By combining the structural strength and dimensional precision of metal components with the biocompatibility and chemical inertness of advanced thermoplastics, these probes deliver exceptional rigidity without sacrificing fluid compatibility.

This carefully engineered material pairing enables tight tolerances and stable probe geometry, ensuring accurate positioning and repeatable performance across instruments. At the same time, the thermoplastic flow path provides a clean, non-reactive interface for biological samples, minimizing contamination risks and preserving sample integrity in sensitive workflows.

The impact is a high-integrity sample probe designed for consistency and reliability. These composite assemblies maintain structural precision and flow path performance over time, even in demanding biological environments. As a result, instrument manufacturers can achieve greater reproducibility, improved data quality, and increased confidence in their analytical systems.
