The Hybrid Mini Extruder is built in the same housing as our proven standard extruders as a table-top execution. As a combination unit, however, it additionally offers the choice between two different extruder sizes. Three variations are available, each with two selectable screw diameters (5, 9 or 12 mm).

During formulation development, often only small and often expensive amounts of active ingredients are available. On the other hand, many formulation trials are necessary to find an optimal formulation. These prerequisites require extrusion capabilities on a resource-saving miniature scale. For this purpose, Three-Tec has developed a Hybrid Mini Extruder.

The parallel twin-screw Hybrid Mini Extruder has very low active ingredient consumption thanks to an empty volume of only 1.2 cm3 with a 5 mm screw diameter (L/D ratio 15:1) – the smallest of its kind in the world. This makes it possible to produce very small batches from as little as 0.5 grams. Since only very small residual amounts remain in the extruder, a high yield can be achieved with the substances available. The results can also be used optimally for reproducible scaling.

Thanks to the universal use of heating cartridges, cooling systems, die plates, pressure and temperature sensors, the unit offers the flexibility to convert from a 5 mm to a 9 or 12 mm screw diameter within a few minutes. The range of applications is thus considerably enlarged compared to conventional extruders. within a few minutes from a 5 mm to a 9 or 12 mm screw diameter.
