Which instrument to choose for pharmaceutical applications?
For viscosity measurements we are recommending:
RST-CPS Rheometer – which measures high viscosity at zero shear rate to determine yield stress values. This is important because like you know most ointments need to be sufficiently thick when standing to prevent them from oozing away from the intended area of use. They also need to flow easily when applied (know as shear thinning behavior).
CT3 Texture Analyzer – the hardness of a tablet, the dissolution of a tablet or the strength of a gel capsule will have an effect on drug release rate in the body.That why we recommend CT3, which accommodates variable geometries while maximizing the value of data obtained.
