The Spheronization Challenge

Free Trials in our development lab

We have a fully equipped formulation development laboratory waiting to receive you and your materials.  We will run extrusion and/or spheronization trials to make pellets with you in our lab and together we will process, measure, iterate and allow your innovation to show early success.  Why not give it a try?
