ACCESSORIES

   
1. Extended Temperature Cell (ETC)
The ETC accessory, based on the Joule-Thomson effect, allows measurements in cone and plate and parallel plate over the temperature range -180° to 550°C. Heating and cooling rates of 20°C/min. are possible in a static environment. Thermal expansion of the cell, measuring system and sample is compensated for automatically. For environmentally sensitive samples, the ETC is equipped with an inert gas inlet.
2. High Pressure Cell
The High Pressure Cell is used for studying rheological properties of samples at pressures greater than 1,500 psig with full viscometry and low frequency oscillatory capabilities. Possible applications include studying processes like drilling mud performance, polymer solution addition, gel formation, crude oil transport at low temperatures, and wax precipitation under varying solids content, temperature, and pressure. The cell can also be used as a miniature polymerization reactor. Temperature range is -20° to 400°C. Maximum pressure is 15,000 psig.
   


3. Extended Pressure Cell
The Extended Pressure Cell allows measurements on samples containing volatile components and pressure induced materials changes to 1,500 psig. The Pressure Cell is hermetically sealed, and driven by a magnetic coupling. Temperature range is -20° to 200°C, the upper limit depends on the sample internal pressure. Back to Top

   

4. Heated Couette Cell (CCE)
The CCE accessory extends the temperature range for concentric cylinders to -100° to 350°C with heating and cooling rates to 20° C/min.. A wide range of couette sizes are available, as well as custom made tooling for special applications, and disposal cups for quick sample exchange. To extend the measuring range of the CCE further, cone and plate, parallel plate, and vane geometries are available.

5. Sealed Cell
The Sealed Cell (patented) allows full dynamic oscillatory and viscometric measurements on volatile samples in a controlled environment. The cell is pressurized by a non contacting air bearing, with cell pressures to 100 psig. Temperature range for the Sealed Cell is -10° to 350°C, the upper limit depends on the vapor pressure of the sample of interest. The Sealed Cell can also be equipped with parallel plate measuring geometries for more viscous samples.

6. UV Cell
The UV cell is used to monitor changes in material properties as a result of exposure to ultraviolet or other frequency light. The cell has a temperature range from -10° to 350°C. The innovative design allows the plates to be easily removed to facilitate working with vitrified samples.

7. Electro-rheological Cell (ER)
The ER Cell allows measurements where an electric field is applied across the sample. The ER Cell is available for both parallel plate, cone and plate, and couette measuring systems. The filed strength can be varied up to 3KV/mm. Temperature range is -20° to 90°C.

8. Fiber/Film Tension Cell
The Tension Cell allows for measurements on thin films and fibers in the temperature range -180° to 550°C.Measurement of Young's modulus, glass transition (Tg), secondary transitions, creep/recovery, and shortening can be performed over the temperature range specified.

9. RheoPolymer Cell
The RheoPolymer Temperature Cell shown above is a convectively heated temperature cell for testing samples at elevated temperatures in cone/plate, parallel plate, rectangular torsion, or fiber/film tension configurations. The cell operates across the temperature range from ambient to 550 °C, and is extendable to - 60°C using an optional air chiller or to -180°C with optional Liquid Nitrogen (LN2) Accessory.

Controlled heating and cooling rates of 20°C/min. are possible. Thermal expansion of the cell, measuring system and sample is compensated for automatically. For environmentally sensitive samples, the RheoPolymer cell can operate with any inert gas supply.
