Samplers for viscous media e.g. pulp, porridge
Viscosity
Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. In everyday terms (and for fluids only), viscosity is "thickness" or "internal friction". Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. Put simply, the less viscous the fluid is, the greater its ease of movement (fluidity).

Sampling viscous products
Sampling viscous products like e.g. creams, pastes is a highly difficult task. The flow behaviour requires a reasonable amount of energy to make the product move in the desired manner.
