Extractables and Leachables

EuTech professional team has proudly been serving the pharmaceutical and medical device industries in analyzing their container closure systems. The issues related to extractables and leachables has always been a great challenge in the food and pharmaceutical industries wherein safety becomes a primary concern with the use of glass, plastic and rubber in a number of packaging materials. We perform these extractables and leachables studies on both organic and inorganic materials, and volatile and non-volatile materials. Our services also include providing qualitative and quantitative data to determine the effects of these components. Our experienced team at EuTech Scientific Services, Inc. will assist in every aspect of your project’s extractable, simulation and leachable study from the initial stages of planning to its execution. We follow PQRI guidelines and make use of the ELSIE database.

EuTech Scientific Services is a recognized support laboratory for many pharmaceutical companies. Work is conducted in our state-of-the-art facilities. We adhere to GLP guidelines of FDA. Our team of highly experienced scientists will work hand-in-hand with you to meet your analytical needs. EuTech staff prides itself on providing accurate, dependable data in a timely, cost and effective manner

All work is performed under strict confidentiality.
