Enhanced resolution for extensional viscosity

Cambridge Polymer Group, Inc. - Extensional Rheometer upgrades

Over five years ago Cambridge Polymer Group invented the Capillary Breakup Extensional Rheometer (CaBER®). CPG is pleased to announce a range of enhancements that greatly improve the flexibility of the instrument and the quality of the data generated.

These enhancements are designed to interface with the existing commercial CaBER® currently marketed by Thermo Haake.

Enhancements:

• Enhanced Resolution
• New data acquisition system improves theoretical resolution to <0.4 μm
• Conductivity Determination of Break-up
• By adding a conductivity sensor between the plates a measure of the breakup-time can be obtained in situations where the laser micrometer is not sufficient, such as for very-low viscosity fluids and for unusual deformation modes.
• Synchronized Video Acquisition
• A separate software modules runs in parallel with the CaBER® software to allow capture of images synchronized to the CaBER® data.
• Black and White
• Maximum frame rate 100fps (720x280 pixels)
• Minimum shutter time 0.5 ms
• Maximum recommended frames 200
