MEASURE VISCOSISTY: AUTOSAMPLER
The Viscotek Model 1223 Autosampler is specifically designed to meet the needs of dilute solution viscosity measurement. It mates seamlessly with the Viscotek Relative Viscometer to provide
automated sample delivery, which frees the operator from the tedious task of manual injection and allows processing of samples in a batch mode. Automation of the sample delivery process also increases sample throughput, efficiency and productivity while enhancing operator safety.
The Model 1223 is an X/Y/Z autosampler with a stationary rack design that provides superior accuracy and reproducibility. It is controlled by the Viscotek ARV software, which also controls data acquisition and processing from the Relative Viscometer. Communication is accomplished via RS-232 or GSIOC.
The autosampler is capable of handling 40 or 20 ml vials and meets all applicable safety and EMC certification standards, including UL and CE. When mated with the Viscotek Semi-Automated Sample Prep (SASP™) station and software, the autosampler provides significant automation of both the sample preparation and delivery tasks.

CAPILLARY RHEOMETER LCR7000
LCR7000, Laboratory Capillary Rheometer
Dynisco Polymer Test's capillary rheometer, LCR7000 Series, meets or exceeds ASTM D3835 specifications. They are microprocessor controlled for automatic
operation and can measure the flow of polymers over a wide range of process conditions.
The best way to determine the polymer rheology is to measure the viscosity over a wide range of shear rates. The instrument can operate from low to high shear rates and automatically monitor as many as 45 measurement points with one barrel loading. The capillary rheometer can be operated in two modes: manual or automatic. The thermal stability can be monitored and reported at constant shear rate.
Important process parameters such as temperature and barrel pressure can be optimized since the capillary rheometer simulates what is occurring in the head area of an extruder or the gate area of an injection molding machine. Regrind (scrap) material can be put to good use since blend variations can be researched to find which is best suited to produce a useable end product. In addition, die swell ratio can also be monitored using an optional laser micrometer system.
The LAB KARS Software for WINDOWS is used for data storage as well as printing, plotting, merging, and automatic curve fitting of the generated data and iseasy to operate. LAB KARS can be used to program the rheometer directly from the PC (bi-directional communication) to reduce setup time. Rabinowitsch and Bagley corrections are performed when possible. Other features include deleting points form the graphic screen, viewing the equations used in curve fitting along with the fitted coefficients and their error estimates, graphically interpolating data, annotation of plots, average Bagley corrected data, IMV calculation and apparent MFV (melt flow volume) calculation, setting up of SQC curves, and reporting die swell ratio using the optional laser micrometer system.
The LCR7000 Series capillary rheometer with LAB KARS software clearly offers the widest range of testing capabilities for both QC and research/development work. The price to performance ratio of the LCR7000 Series can not be matched.
Features:
All digital calibration
Increased force and speed range
Advanced electronics & 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
Precision servo-drive motor and transducers enable tight control of stress and rate mode tests

MEASURE VISCOSITY : DUAL DETECTOR
Viscotek's Dual Detector is specifically designed to be added to an existing GPC/SEC system equipped with a concentration or light scattering detector, instantly converting it into a triple detector
system.
In triple detection, the patented 4-capillary differential viscometer provides a direct measurement of intrinsic viscosity and allows for the determination of molecular size, conformation and structure. The light scattering detector provides a direct measurement of absolute molecular weight and eliminates the need for column calibration.
The Dual Detector is configured with the differential viscometer and a light scattering detector (LALS or RALS). It is also available as a stand-alone viscometer or light scattering detector. This flexibility allows you to choose the configuration that meets your specific application requirements, insuring superior performance while maximizing the information from your GPC/SEC experiment.
