PolyVISC SPS Solution Preparation System
- Prepares polymer solutions for relative viscosity measurements using weight-to-weight methodology
- Eliminates errors due to variations in solvent density and cumbersome manual weight and volume measurements
- Provides concentration accuracy often better than ±0.02%
The PolyVISC SPS Solution Preparation System from CANNON Instrument Company is a semi-automated solution preparation system that uses gravimetric rather than volumetric methodology. The SPS can be used with the CANNON PolyVISC (see new PolyVISC options, next page) Automatic Viscometer to provide a complete polymer analysis system.
New PolyVISC Options
The CANNON PolyVISC Automatic Glass Capillary Viscometer combines automatic sampling, viscosity measurement, viscometer washing, and polymer solvent compatibility to provide a convenient benchtop unit ideal for dilute solution polymer viscosity analysis. Both transparent and opaque samples can be measured with the accuracy required by ASTM D 2857.
A Kynar® coating upgrade is available for the PolyVISC instrument. The AIRBATH interior is coated with this durable polyvinylidene fluoride (PVDF) compound. The upgrade permits testing with highly aggressive solvents, including concentrated sulfuric acid. The Kynar coating upgrade also includes a Kynar wash platform and solid Teflon sample carrier and wash station.
PolyVISC viscometer tubes Two tube types are available for the PolyVISC instrument. The modified Atlantic compound viscometer tube is suitable for most samples. The modified Ubbelohde tube is particularly suited for more volatile samples, and may significantly enhance determinability and repeatability.
Zematra ASA Automated Stability Analyzer
- For process monitoring of residual refinery streams and fuel oils
- Determines the P-value and the Po/Frmax of residual fuel oils
- Complies with Shell Methods SMS 1600 and SMS 2715
- Uses modern fiber optics techniques for improved detection
The Automated Stability Analyzer manufactured by Zematra® uses the latest fiber optic techniques to greatly improve detection of the flocculation point and repeatability of the results. Because the unit is automatic, manpower requirements are minimal and repeatability is improved. Windows-based software performs all calculations. Data from previous runs may be easily accessed and processed using the supplied Dataview software.
Drive Line Rotor Kit for testing per ASTM D 6821
Drive Line rotors specifically designed for the ASTM D 6821 test method are available from CANNON® (see Order Information below). The Drive Line Rotor Kit includes nine DL-type rotors with specially designed geometries appropriate for drive line fluid testing. The Kit also includes a copy of ASTM D 6821 (Standard Test Method for Low Temperature Viscosity of Drive Line Lubricants in a Constant Shear Stress Viscometer) and a weight set with mass increments of 2.5 grams.
The temperature profile for this method consists of a 1.5-hour soak at 50°C ± 1°C, a 2-hour nonlinear cool-down to the test temperature (+10 to -40°C), and a 14-hour soak ± 0.02°C at the test temperature. The entire temperature profile, up to the point of measuring yield stress and viscosity, requires 17.5 hours.
