SELECTED EQUIPMENT
Rheology, mixing and extrusion.
Explore drive units, mixers and extruders alongside equipment for sample preparation and testing. Confirm attachment compatibility and available configurations with GRS.
Torque rheometer drive unit
The drive and measurement base for compatible mixer and extruder attachments. Controlled rotation and torque measurement help laboratories study processing behaviour and compare formulations.
Ask about this equipment ↗
Laboratory internal mixer
Mix small batches under controlled conditions to study material behaviour during mixing. Torque response helps compare formulations and assess changes as the material is worked.
Ask about this equipment ↗
Single-screw extruder
A rotating screw conveys and plasticises material, then pushes it through a die. Use laboratory extrusion to explore processing conditions and prepare samples with suitable downstream equipment.
Ask about this equipment ↗
Conical twin-screw extruder
Two tapered screws convey and mix material through the barrel. Explore formulation and processing trials with screw geometry and operating conditions selected for your material.
Ask about this equipment ↗
Counter-rotating twin-screw extruder
Two parallel screws rotate in opposite directions to convey and process material. Discuss this configuration for laboratory extrusion trials and material-specific processing requirements.
Ask about this equipment ↗
Co-rotating twin-screw extruder
Two parallel screws rotate in the same direction to mix and compound materials. Explore incorporating additives, comparing formulations and developing processing conditions at laboratory scale.
Ask about this equipment ↗
Two-roll mill
Two rotating rolls work material through a narrow gap to mix polymers or rubber with fillers, pigments and other additives. The mill can also form sheets for further testing.

Dynamic testing oven
Controlled-temperature testing helps assess how heat affects materials over time. The catalogue lists ageing temperature and time settings; contact GRS to confirm the specific test functions of this model.
Ask about this equipment ↗
Planetary mixer
The mixing tool rotates while travelling around the bowl to blend viscous materials such as polymer compounds, pastes, adhesives and sealants. Heating and vacuum capabilities depend on the configuration.
