Description
LCR 7000 Series
The new LCR7000 series capillary rheometers offer many new features and meet the requirements of 24-hour shop-floor operation while maintaining the highest possible levels of accuracy, repeatability and sensitivity. LCR series rheometers are versatile and easy to use, yet offer the most sophisticated material characterization, data analysis and reporting capabilities. LCR series rheometers can be used with a standard load cell and a pressure transducer mounted in the barrel.
SOPHISTICATED SOFTWARE
LAB KARS ("Kayeness Advanced Rheology Software") is the most powerful and easiest-to-use rheology software package for Windows™. Its easy-to-use features include Bagley and Rabinowitsch corrections and power law, Carreau, Modified Cross and polynomial viscosity models. With this software, users can merge multiple data files from shear stress, shear rate or thermal stability tests. The resident KARS SQC module can be used to quickly identify viscosity changes between different material batches. A program for correlating melt viscosity with intrinsic viscosity for PET and nylon is also included.
REAL-TIME DISPLAY
In addition to all its other powerful features, LAB KARS for Windows™ provides a real-time display of force or pressure versus time during the test. This feature allows the operator to identify steady-state material flow. In addition, spikes in the force-versus-time curve can reveal the presence of contamination, unmelted resin or bubbles in the material.
Features
■ All-digital calibration
■ Wider speed and force range
■ Advanced electronics and software allow up to 45 shear stress or shear rate data points per test
■ Unique algorithms for polymer melt stability
■ Bidirectional communication allows test parameters to be downloaded from a computer
■ Multiple barrel heating zones and an adaptive PID temperature control algorithm ensure accurate and uniform heating up to 430 °C (500 °C optional for models 7000 and 7001 only).
■ A precision servo motor and transducers allow tight control of tests in load and speed modes.
■ Tungsten carbide and a hardened and ground tool steel body ensure a long service life.
