HORIZONTAL EXTRUDERS​

The processing unit of our Twin-Screw Extruders is a clamshell “easy clean” barrel with interchangeable, segmented screws that can be reconfigured to a specific application by selecting various kneading, mixing, and shear screw elements.

Additionally, we offer a wide range of Pre/ Post extrusion options :

We offer 10mm, 21mm, twin screw extruders – all in various L/D ratios (10/25/30/40)

The screws are co-rotating, intermeshing, and self-cleaning. All material contact surfaces are GMP & FDA compliant upon request.

Minimum quantities of high value samples can be processed with the unique Microlab 10mm which enables time and cost savings in method development, procedure optimization and preparation for scale-up production from our 10mm to our 21mm twin screw extruders.
