What do our customers 
think? 
We recently engaged Diteba to undertake an IVRT study for a topical spray 
formulation using the finite dose technique and static Franz Diffusion Cells. Not 
only did they resolve some very difficult technical obstacles, but they completed 
the project to our complete satisfaction. I am pleased we chose them to be our 
IVRT partner.
