Viscometers & Rheometers

Showing all 11 results

    • Uses smaller material quantities for faster, cost-effective development
    • Converts easily from hot melt extrusion (HME) to twin screw granulation (TSG) applications
    • Operates at throughput ranges from 20g/h up to 2.5kg/h
    • Processing length: L/D ratio 40:1
    • Screw elements and barrel design scale geometrically across the all Thermo Scientific Pharma Extruders and allow easy process scale-up
    • Easy-to-operate with user-friendly, intuitive touch screen with integrated feeder control
    • Maximize lab space with small footprint machine
    • Perfect for glove box or isolator applications with removable touch screen
    • All material contact parts are easily removable
    • Documentation of extrusion parameters and suitable for process analytical technology (PAT)
    • GMP-compliant, full validation available: FAT, SAT, IQ/OQ


    • 2-in-1 process design – quickly disassemble parts for easy cleaning and process switching from HME to TSG.
    • Simple continuous process integration – plug-and-play functionality with upstream and downstream process equipment (e.g., feeders, chill rolls, pelletizers, dryers, etc) simplifies production line design.
    • Less optimization time, cost and effort – extruder process parameters are scaleable to larger Thermo Scientific extruders due to geometric similarity with minimal use of expensive ingredients.


    • Horizontally split barrel (up to 40:1 L/D) is hinged for easy access to the screws; simple screw removal device promotes quick and easy cleaning and configuration changes
    • Barrel is constructed in segmented modules that can be reconfigured to suit a variety of polymer processes
    • Replaceable barrel liners can be made from special materials for abrasive or aggressive applications
    • Barrel segments are available for feeding solids and liquids or for venting
    • Secondary feeders and vacuum pumps can also be incorporated into the system
    • Powerful control software is programmed to recognize plug-in ancillaries
    • Large color touch screen interface incorporates on-screen, real-time trend display


  • Overcome drug formulation challenges

    Pharmaceutical manufacturers are using conical and twin-screw extruders to mix drug molecules with bioactive polymers in situations where drug ingredients are poorly soluble or unstable during processing. Extruders are also useful in preparing enteric dosages, sustained release dosages, in taste-masking, and to create forms such as films.

  • Gain the advantages of a continuous process

    Continuous granulation offers a more efficient and cost-effective route for producing tablets and capsules, particularly when developing new formulations where scale-up is difficult due to the narrow optimal working points found in batch devices such as mixers, agitators and choppers.


    • Requires only 3g (4mL) of material for compounding
    • Small footprint, fanless design with separate, touch-screen control for operation in fume cabinet or glovebox applications
    • Removable and exchangeable product contact parts for quick and easy cleaning
    • IP 54 for protection against dust and water allows the Pharma mini HME to be spray-washed
    • Useable as small-scale production unit for throughputs of 100g/h
    • Touch screen control with user levels and password protection
    • Data logging software as option to record temperatures, torque, and screw speed
    • Optional batch conversion kit to use the Pharma mini HME as small batch mixer
    • Complementary workflow solution when coupled with the Thermo Scientific™ HAAKE™ MiniJet injection molder


  • Confidently meet all your quality control demands with the Thermo Scientific™ HAAKE™ PolyLab™ QC Modular Torque Rheometer. The HAAKE PolyLab QC Modular Torque Rheometer can be connected to an interchangeable mixer, single-screw extruder or conical twin-screw extruder — combining proven technology and state-of-the-art hardware and software with an easy-to-use interface.


  • These small, battery-operated rotational viscometers are suitable for quick and reliable tests and comparative measurements for quality control applications. The hand-held instruments can also be operated on a stand.

    Main features

    • Quick, exact and reliable
    • One button operation
    • LCD display
    • No mains supply required
