The rotary shear module for measuring friction parameters includes a vessel containing the sample more info powder check here plus a shear head to lead to typical and shear stress50. The blades with the shear head sink into the mass powder as well as front facial area of The top begins to apply standard worry towards the floor from the powder bed. The shear head moves downwards until finally a enough and steady force is used among The pinnacle and powder mattress.
Liquid varieties including solutions, suspensions, emulsions and syrups may also be outlined. The doc provides details on modified release stable dosage types and Unique types of tablets. It concludes by covering topical, parental and inhalational dosage kinds.
