What Is Extractables Leachables Guide?
Extract analysis evaluates the soluble components that migrate or leach from materials when exposed to specific solvents under controlled conditions. It is widely used to identify extractable substances that may affect product performance, safety, or regulatory compliance.
This testing is critical for materials used in packaging, medical devices, and chemical systems, where interaction with liquids can lead to contamination or degradation. It supports material characterization and ensures suitability for intended applications.

Our Testing Procedure
Sample Preparation
The material sample is cleaned, cut, and prepared to a defined surface area or weight for controlled extraction conditions.
1Solvent Exposure
The sample is exposed to a selected solvent under controlled temperature and time to extract soluble components.
2Extract Collection & Analysis
The extracted solution is collected and analyzed using analytical techniques to identify and quantify components.
3Data Interpretation & Reporting
Results are evaluated to determine extractable levels, composition, and compliance with applicable standards.

Extractables Leachables Guide FAQs
Extract analysis identifies potential compounds that can be released under aggressive conditions, while leachables studies evaluate actual migration under real-use conditions, making extractables a worst-case screening for chemical risk assessment.
Different solvents simulate various chemical environments and polarity ranges, ensuring comprehensive extraction of both polar and non-polar compounds that may be present within the material matrix.
Elevated temperatures increase diffusion rates and solubility, enhancing extraction, but may also induce degradation or formation of secondary compounds, requiring careful interpretation of results.
Extract analysis identifies all potential extractable compounds under extreme conditions, while leachables testing evaluates actual migration under real-use conditions, providing a more realistic exposure assessment.
Longer extraction times allow compounds to reach equilibrium between material and solvent, increasing completeness of extraction but potentially introducing degradation or secondary reactions.
