Coperion twin screw compounder for processing smallest batch sizes

The laboratory extruder STS 25 Mc¹¹ is based on the successful STS technology. It was developed especially for the processing of smallest batch sizes.

The STS 25 Mc¹¹ boasts all the advantages of the STS series, has a simple design, is operator-friendly and easy to clean. The base frame has a closed, simple to clean surface and is equipped with castors for easy movement of the extruder and fast installation.

By having the same screw diameter ratio Do/Di of 1.55 and a specific torque Md/a³ of 11.3 Nm/cm³, production parameters of the STS 25 Mc¹¹ can be reliably scaled up to larger STS sizes which makes it the ideal compounding system for recipe development and basic scientific research.
