Transdermal permeation Franz cell

Overview
The Franz Cell measures cumulative permeation and absorption rates of active compounds across membranes to predict transdermal drug kinetics. It is designed for laboratory transdermal and topical penetration testing in pharmaceutical and biomedical research.

Introduction
Designed for vertical transdermal experiments, the Franz Cell is suitable for testing penetration of solids and semi-solids (e.g., ointments, patches) through human or animal skin, skin models, cornea and other membranes. It supports routine in vitro release and permeation studies with controlled stirring and temperature.

Key features

• Precise temperature control: accuracy 0.2℃, adjustable from room temperature up to 70℃.
