Table of Vanes for the RST-SST Soft Solids Tester
All standard vanes supplied for the Soft Solids Tester have a height (H) to diameter (D) ratio of 2:1.
The constants for the standard vanes are as follows:

The vanes pre-loaded into the Rheo3000 software assume a ratio of 3:1 (container-to-vane diameter). If
you use vane/container combinations that don’t match this select an appropriate value from the following
table:

It may be possible to use a vane spindle with the MB measuring chamber. This combination can be used
to measure flurries (fluids with suspended particles). Contact Brookfield or your authorized deaer for more
information.
