EC-Twist is a dynamic mechanical analyzer for DMTA analysis on solids as well as liquids. The modular system performs measurements in torsion and extension and is the first DMTA solution that can also be used for shear rheological experiments – at unprecedented precision.
Key Features
Highlights
EC-Twist can be used to analyze solutions, melts, solid bars, films, foils or reactive resins
Performed on highly diverse samples for full flexibility ensured by a wealth of different measuring systems and temperature devices
DMTA tests in torsion or extension, as well as shear viscosity determination and extensional rheological tests Fully digital instrument employing the latest DSP (Digital Signal Processing) technology
High-precision air bearing, including a patented normal force sensor
Ease of use
Toolmaster™: Patented system for automatic recognition of measuring systems and accessories
Quickfit coupling: Easy, one-hand measuring system connection in both drive units
T-Ready™: Reduced waiting times by detecting and signaling sample temperature equilibration
Wide range of measuring systems for all kinds of applications
USB connection to computer/software
Ethernet connection for remote control of the instrument through the company network
RheoCompass™: User-friendly application software
High precision
Decoupling of sample pretension (stepper motor) and excitation (EC motor) considerably increases the system's precision for solid bar measurements
EC-Twist's peak performance is based on technological highlights such as the air-bearing-supported, synchronous EC motor, TruRate™ sample-adaptive motor control, TruStrain™ real-time position control or the patented normal force sensor
Wide range of accessories
Devices for temperature control ranging from -150 °C to 1000 °C
Special accessories for DMA and DMTA measurements, rheo-optics, magneto- and electrorheology, interfacial rheology, UV curing and many other applications
