DVVA II - Dynamic Void Volume Analyzer

DVVA II - Dynamic Void Volume Analyzer

Micromeritics | Material Characterization, Surface Area and Pore Size

The DVVA® II is a state-of-the-art dynamic void volume analyzer capable of measuring the compressed void volume and density of carbon black powders and with exceptional precision and ac­curacy. 

This instrument can be used to predict the optimal polymer/carbon black ratios in polymer-reinforcing materials, providing an automated alternative to the oil absorption test, while satisfying the requirements of ASTM D7854-16 test method.

The DVVA II can be used to accurately measure the fundamental property of carbon black aggregate structure by calculating the void volume of a sample under compression, providing an automated cleaner/greener alternative to the oil absorption test, while satisfying the requirements of ASTM D7854-16 test method. Having a high resolution set of data that describes the void volume vs. geometric mean pressure characteristics of the material is a fundamental step in understanding, controlling or predicting phenomena related to void volume.

Features:

  • Meets all requirements of ASTM D7854-14 test method, with the use of two independent load cells
  • Fully automated instrument control 
  • USB connection to PC
  • Windows 7 operating environment
  • Safety features prevent operation until safety barrier is in place
  • Variable sample size
  • User-replaceable piston tip
  • Compression scan results in less than 5 minutes
  • Automated corrections to data
  • Exceptional precision
  • Hydraulic fluid not needed 
  • Ejects compressed sample for further testing
  • Free of hazardous materials and waste
