Choosing the right screw diameter is crucial for a laboratory extruder. If you don't want to limit yourself and want to carry out test series with different diameters, the laboratory extruder hybrid is the ideal solution.<\/strong><\/p>\n\n\n\n

In the early phase of formulation development, researchers often only have access to very small and often cost-intensive quantities of active ingredients. At the same time, the development of an optimal formulation requires numerous series of tests. This combination of limited resources and high experimental requirements places particular demands on the process technology used. With the laboratory extruder hybrid, Three-Tec offers a solution that has been specially developed for extrusion processes on a resource-saving miniature scale.<\/p>\n\n\n\n

As a combination device, the parallel twin-screw laboratory extruder hybrid offers a choice of two different extruder sizes. Three variations are available, each with a choice of two screw diameters (5, 9 or 12 mm). The variant with a 5 mm screw diameter and an L\/D ratio of 15:1 in particular drastically reduces the consumption of active ingredients or target materials thanks to an extremely small empty volume of just 1.2 cm\u00b3. Very small batches can be produced from as little as 1 gram. As only very small residual quantities remain in our laboratory extruders, a high yield of the materials used is achieved. With an initial quantity of one gram, for example, an extrusion quantity of 0.7 to 0.8 g is realistic. The results provide a reliable basis for reproducible scaling up to larger production scales.<\/p>\n\n\n\n

A key feature of the laboratory extruder hybrid is its high degree of flexibility. Thanks to the universal use of heating cartridges, cooling systems, die plates and pressure and temperature sensors, the extruder can be converted from a 5 mm to a 9 mm or 12 mm screw diameter in just a few minutes. This significantly extends the range of applications compared to conventional laboratory extruders. The modular design of the screws with conveying, return, mixing and kneading segments - even in our smallest extruder - allows precise adaptation to a wide range of extrusion processes.<\/p>\n\n\n\n

With the laboratory extruder hybrid, Three-Tec combines resource-saving work, high flexibility and precise process control. For research teams working with small and valuable quantities of material, this technology opens up new possibilities for developing formulations faster and more economically.<\/p>\n\n\n\n
