New Non-PFAS Low Retention Additive for Pipette Tips

Avient’s new non-PFAS low retention compound helps achieve high fluid release from pipette tips with its efficient non-fluorinated hydrophobic system, supporting accurate and consistent test results. This ready-to-use solution is manufactured under a holistic change control program to reduce the risk of performance and quality issues.

Avient Corporation, an innovator of materials solutions, launched its latest Mevopur™ Healthcare Functional Additive on November 14, 2025: a non-PFAS, low-retention compound for pipette tips.

Avient’s Mevopur portfolio includes performance and processing-enhancing additives that can reduce friction, improve clarity, enable laser marking and welding, and offer protection against ultraviolet (UV) light, oxidation, and gamma and/or e-beam sterilization. The new, low-retention materials solution, formulated without intentionally added per- and polyfluoroalkyl substances (PFAS), slip agents, plasticizers, or biocides, can be used to enable excellent fluid release from polypropylene pipette tips in scientific and medical laboratory settings. 

Available as a ready-to-use compound, this low-retention additive solution eliminates the need for secondary low-retention coatings and can be adapted to customer requirements. It can also withstand typical electron-beam and gamma radiation sterilization doses applied to pipettes (usually up to 15 kGy) with fast recovery of hydrophobicity post-radiation. Additionally, its raw materials are pre-tested to ISO, USP, and ICH Q3D protocols for manufacturers who wish to use medical-grade materials for their pipette tips.

“This non-PFAS low retention additive technology not only delivers effective hydrophobicity without fluorinated substances; it’s also developed and manufactured under a holistic change control program. This can help to reduce the risk of performance and quality issues that could occur from changes in raw materials and manufacturing process,” says Volker Dickfeld, Senior Marketing Manager Healthcare Global for Color & Additives at Avient.
