The Dynamic Stability Loop (DySL) by PSL Systemtechnik was designed to test long-term stability of umbilical chemicals in the lab at very stringent conditions. The DySL combines up to six loops for measurements of long-term changes of viscosity and tube blocking tendencies at pressurized conditions.
