Phoenix Flex Automated Diffusion
Fully automated IVPT workflow meeting USP & FDA requirements, with membrane and media temperature monitoring plus blank collection before dosing.
The Phoenix Flex is a truly innovative new diffusion tester for permeation research of skin flux, introduced by Teledyne LABS in early 2026. Packed with benefits for In Vitro Permeation Testing (IVPT) of transdermal drug delivery and other topical and transdermal substances, it provides fully automated filling, collection, rinse, refill, wash, and bubble removal to streamline regulated workflows. It’s operated by 21 CFR Part 11–compliant control software, making the Phoenix Flex a powerful IVPT solution designed specifically to meet USP <1724> and FDA requirements for full media replacement or large aliquot replacement in IVPT studies.
