Available in two versions, to work at above ambient temperature and below ambient temperature. General Descripation & Specifications Double walled, outer chamber made of G.I. - powder coated, with removable toughened Glass window panel, inner chamber made of S. S, FHP motorised stirrer for uniform temperature, Dual Display Microprocessor Based Digital Temp. Controller with PT-100 sensor. Temperature range from 5° C above ambient to 100° C., Control accuracy ± 0.1°C. Below ambient Viscosity Baths are fitted with Refrigeration system (Temperature Range : 10°C to 100°C). The Baths can accommodate 2 / 4 / 8 Viscometers with varying tank volumes. Stainless steel bath Temperature controller (Thermostatic/Digital) Immersion electric heater Constant speed Pump cum stirrer Carriage holding up to three standard briquette moulds Electric motor with gear mechanism Stainless steel scale and pointer Control Panel Reverse Flow Viscometer The viscometer is made of clear borosilicate glass free from visible defects. All glass tubing used in the construction of a single viscometer is of the same composition and the finished instrument is thoroughly annealed. The design and details of the viscometer are given at side. The size, approximate constant and Kinematic Viscosity is as per table. Cannon Fenske Viscometer For opaque and transparent liquids : detailed drawings of the reverse flow ‘Cannon-Fenske’ viscometer is given in the figure. The size, approximate constant and kinematic viscosity range, is given in the table.

Features and Benefits All digital calibration Increased speed and force range Advanced electronics and software enable up to 45 shear stress or shear rate data points per test Unique algorithms for polymer melt stability Bi-directional communications enable test parameters to be downloaded from the PC Multiple barrel heating zones and adaptive PID temperature control algorithm provide precise and uniform heat up to 430°C (500°C optional for Model 7000 and 7001 only) Precision servo-drive motor and transducers enable tight control of stress and rate mode tests Tungsten carbide dies and a hardened and honed tool steel barrel ensure long years of service LAB KARS, advanced rheology software Description Versatile The new LCR7000 Series Capillary Rheometers offer many new features and will meet the demands of a 24-hour-a-day shop floor operation while maintaining the highest possible level of accuracy, repeatability and sensitivity. The LCR series rheometers are versatile and easy to use yet they offer the most sophisticated materials characterization, data analysis, and reporting capabilities. The LCR series can be used with a standard load cell and a barrel mounted pressure transducer. Sophisticated Software LAB KARS (“Kayeness Advanced Rheology Software”) is the most powerful and easy to use rheological Windows™-based software package available. Just a few of its easily useable features include: Bagley and Rabinowitsch Corrections plus 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 variations in different lots of material. A program for the correlation of melt viscosity to intrinsic viscosity, for PET and Nylon, is also included. Real-Time Display In addition to all of its other powerful features LAB KARS for Windows™ provides a real time display of force or pressure versus time as a test progresses. This feature allows the operator to identify the steady state flow condition for the material. In addition, the presence of contamination, unmelted resin, or bubbles in the material may be identified from spikes in the force versus time curve.

Rheological evaluation through controlled stress measurement offers superior viscosity profiling, thixotropic response, yield stress determination and creep analysis. The Brookfield RST Rheometer offers both controlled rate and controlled stress measurement. Available with coneplate, plateplate, or coaxial cylinder measurement geometry, the RST Rheometer offers powerful flow characterization tools including ramp, loop, and single point testing. A wide range of shear rate, shear stress, and torque provide flexible flow analysis including creep and yield measurement. The RST Rheometer is designed to accommodate the high throughput required of quality control laboratories. It also offers the sophisticated flexibility required of research environments. The RST Rheometer provides cost effective, worry free operation for a variety of laboratory applications.
