Wall shear stress is the force generated by flowing medium and acting on the surface of a cell culture channel. Use this calculator to define shear stress in your experiment when flow conditioning of an adherent cell layer on the channel wall is needed.

Wall shear rate describes the flow profile at the channel wall. It influences all interactions between the channel wall and cells or particles moving with the fluid flow.

Define the shear rate if you are performing adhesion assays with cells or particles in the medium.
