• M5600 Options: Proppant Slurry Testing Accessory Kit | Clear Sample Cup

Proppant Slurry Testing Accessory Kit
The Grace Instrument M5600 Proppant Slurry Testing Accessory Kit incorporates years of research into its innovative design. This kit includes a B2 proppant bob with fins.

Clear Cup
A Grace Instrument M5600 Clear Sample Cup option is also available for the M5600. Its innovative clear, see-through design allows users to see fluid interaction with the bob. (For use under ambient pressure and temperatures only).

Special U.S. patented hollow bob can test rheology and helps overcome the Weissenberg Effect
The M5600’s oscillatory option includes a special, U.S. patented hollow bob that allows researchers to test the rheology of non-Newtonian fluids and help overcome the Weissenberg effect. The bob design features off-centered axial direction holes, which creates a circulation path to refill the gap in the measurement zone should the liquid sample in the cup climb out, due to the Weissenberg effect. Because of the differential shearing at the bottom of the cup and the bob, along with the pressure difference if the measurement gap is vacant, tested fluid tends to refill the measurement zone and recirculate along the measurement zone if the Weissenberg effect occurs. Thus, the configuration of the hollow bob enables repeatable and reliable test operation using a broad selection of test fluids, methods, and environments.
