Shear Stability Tester

Adopts Germany Bosch dual piston jet pump and atomizing chamber with nozzle & nozzle holder. It is suitable for evaluation of the shear stability of polymer-containing fluids by measuring the percent viscosity loss at 100℃ of polymer-containing fluids. The viscosity loss reflects polymer degradation due to shear at the nozzle.

Product Model: R-SY-0103
Design Standard: ASTM D6278
