PTFE SUSPENSION CUPS
Testing semisolids with paddle method (USP 2)
Testing so-called semisolids - such as ointments, creams, lotions and gels - is often a difficult and time-consuming task. Complex methods such as the so-called "vertical diffusion cell" - also known as the "Franz cell" - are often used here. Alternatively, the "immersion cell" (USP, Chapter <1724>) offers a comparatively simple application with the USP apparatus 2 (paddles) and the desired membranes.
If the use of membranes is not or initially not necessary (method development), results can be achieved quickly and easily with the "PTFE Suspension Cups" and the USP Apparatus 2 method (paddle method).
