Extractables and Leachables (E&L) Testing Services
Resolian’s dedicated E&L team delivers bespoke study design, unknown compound characterization, and toxicological risk assessment – all aligned to FDA, EMA, ISO 10993, USP <1663>/<1664>, and BPOG/ELSIE best practices. GMP and GLP compliant. FDA and MHRA inspection ready.
E&L expertise from study design to regulatory submission - across pharma, medical devices, and biopharma.
What sets Resolian apart is not just the breadth of our analytical capability – it is the depth of our scientific expertise. Our E&L scientists don’t just run samples; they design studies, identify unknowns, and guide clients through complex regulatory landscapes.
Resolian’s dedicated Extractables and Leachables (E&L) team provide the data to allow assessment of the safety and compatibility of your product with its selected storage and delivery devices, as required by regulators. This analytical data will enable you to profile extractables from the primary packaging or device materials, and target leachables in the final product.
We deliver tailored study design for E&L in line with the latest regulatory guidelines, including FDA/EMA, BPSA, PQRI, and ISO-10993, USP 1663/1664, 665/1665, and following BPOG & ELSIE best practices.
Tailored solutions to your extractables and leachables requirements supporting you from early stages of development through the full lifecyle of your product.
Extractables and leachables (E&L) testing provides vital information concerning the potential for impurities deriving from container closure systems, drug delivery devices and manufacturing processes.
This contamination can present a risk in terms of both patient safety and product efficacy.

Tailored E&L Testing for Pharmaceutical, Medical Device, and Biopharma Products
Resolian offers extensive expertise in assessing extractables and leachables testing, including:
Pharmaceuticals
Expert E&L testing for pharmaceutical products using state-of-the-art instrumentation.
Comprehensive analyses ensure safety and compliance for container closure systems of injectables, ophthalmics, topicals, and inhaled products, while maintaining product integrity.
Medical Devices
Resolian analyzes both whole products and components for biocompatibility to detect extractables.
Tailored studies compliant with ISO‑10993 enable chemical characterization of the material, exhaustive and exaggerated extraction of wound dressings, catheters, implants, and other devices.
Biopharmaceuticals
Comprehensive E&L testing for biopharmaceuticals, including pre-filled syringes and single-use systems, aligned with USP <665>, <1665>, and
ISO-10993.
State-of-the-art analytical platforms ensure compatibility and safety of transfer systems (IV bags, tubing, connectors) and process contact materials, following BPOG & ELSIE best practices.
Process-equipment related leachables (PERLs) Testing for Single-Use Systems
Product contact manufacturing components pose a risk of releasing process-equipment-related leachables (PERLs), impacting the efficacy and safety of biopharma products.
Resolian excels in E&L study design and execution for single-use systems (SUS), multi-use systems (MUS), and container closure systems, aligned with USP <665>, <1664>, <1665>, ICHQ3E, and BPOG & ELSIE best practices.
Consumer Healthcare
E&L testing for container closure systems, including plastic and glass bottles, laminated tubing, and stoppers, following USP, ISO, and ICH guidelines.
Extractable analysis for creams, ointments, toothpaste, and shampoo ensures compliance with global regulatory standards for safety and efficacy.
Electronic Nicotine Delivery Systems (ENDS)
Specialized E&L testing for ENDS device components and e-liquid container closure systems.
Identification and quantitation
of components with the potential to migrate into e-liquids or vapors under ISO- 10993. Comprehensive analysis ensures compliance with FDA, TPD,
and other regulatory standards.
