HAAKE™ Rheomix OS Lab Mixers for the HAAKE™ PolyLab™ OS system

Choose a Thermo Scientific HAAKE Rheomix laboratory mixer when your primary goal is to evaluate mixing behavior, formulation development, and material characteristics using small laboratory sample volumes. HAAKE Rheomix laboratory mixers measure torque and melt temperature during controlled mixing, making them well suited for investigating plastification, curing, melt viscosity, additive dispersion, formulation consistency, and processability.

Choose a Thermo Scientific HAAKE Rheomex laboratory extruder when you need to evaluate continuous extrusion processes, material flow, pressure development, extrusion stability, or process conditions that more closely represent production extrusion. HAAKE Rheomex laboratory extruders are well suited for extrusion process development, material evaluation, and optimization of continuous polymer processing.

Because both processing units are compatible with the HAAKE PolyLab OS torque rheometer platform, laboratories can use the same modular drive system

Choose a Thermo Scientific HAAKE Rheomix laboratory mixer to evaluate how formulation changes affect material processing behavior before moving to larger-scale processing.

By measuring torque and melt temperature during controlled mixing, the system can be used to compare the effects of fillers, pigments, stabilizers, lubricants, nanoparticles, and other additives on melting behavior, plastification, viscosity, curing, and material stability. These laboratory-scale measurements help optimize formulations, compare candidate materials, and support process development while using relatively small sample quantities. When additional process evaluation is needed, the HAAKE Rheomix laboratory mixer can be used as part of the HAAKE PolyLab OS platform together with laboratory extruders for further material characterization.

A Thermo Scientific HAAKE Rheomix laboratory mixer helps evaluate material behavior under process-relevant conditions by recording torque and melt temperature during controlled mixing.

The resulting rheogram can be used to investigate melting behavior, plastification, curing, degradation, melt viscosity, additive effects, energy consumption, and formulation consistency. These measurements support material development, process optimization, and quality control by helping compare materials and formulations under consistent laboratory conditions.

Thermo Scientific HAAKE Rheomix laboratory mixers can be used to characterize a wide range of highly viscous materials, including thermoplastics, thermosets, elastomers, rubber compounds, polymer blends, and formulations containing fillers, pigments, nanoparticles, lubricants, stabilizers, or other additives.

Typical investigations include melting behavior, plastification, curing, degradation, melt viscosity, additive dispersion, and processability using laboratory-scale sample volumes.

Choose the Thermo Scientific HAAKE Rheomix laboratory mixer based on your material type, temperature requirements, and laboratory batch size.

• Rheomix 600 – General-purpose laboratory mixer for testing thermoplastics.
• Rheomix 610 – Similar to the Rheomix 600, with liquid temperature control for applications requiring temperatures below 100° C.
• Rheomix 540 – Designed for thermosetting materials and applications where easy removal of cured samples is important.
• Rheomix 3000 – Large-volume mixer for producing larger laboratory batches and testing rubber compounds.
• Rheomix 3010 – Similar to the Rheomix 3000, with liquid temperature control for lower-temperature applications.

All models are compatible with the HAAKE PolyLab OS torque rheometer platform and support material characterization, formulation development, and quality control.
