  • Overview
  • Technical data

Innovation for the pharmaceutical industry

The PTSE® 20/40 is a pilot scale twin screw extruder (screw diameter 20 mm, processing length 40 D). The solid design as well as the convincing technical features makes the PTSE® 20/40 an ideal solution for laboratory applications.

The processing unit is a clamshell design with removable liner for easy cleaning and sterilization. The screws are a segmented modular screw design enabling the operator to optimize the compounding application by utilizing various kneading, mixing, and shear elements of the screws. The segmented screw elements are interchangeable and can be realigned to adapt to a specific application.
