    Jul 26, 2020· Hardness is sometimes termed the tablet crushing strength. To perform this test the tablets are located between two anvils and force is applied to the anvils, and the strength required to break the tablet is noted. Different types of apparatus are used to study the dissolution test of the tablet. As per IP apparatus I (paddle) and apparatus

  • Quality Control Tests for Tablets Pharmapproach

    Oct 01, 2018· Currently, electrically driven hardness testers such as those manufactured by SOTAX, Key, Van Kel, Erweka, Dr Schleuniger Pharmatron etc., are widely used to measure crushing strength of tablets. These equipment eliminate the operator variability encountered with manual hardness testers. Newer equipment with printers are also availe.

  • Crushing strength, disintegration time and weight

    Jun 01, 1997· Tablets compressed from 16 different mixtures of Avl® grades PH-101, PH-102 and PH-200 were studied using a mixture design. The crushing strength, disintegration time and weight variation of tablets were determined after compressing with an upper punch force up to 30 kN.

  • <1217> TABLET BREAKING FORCE

    The breaking force of tablets is commonly called hardness in the pharmaceutical literature; however, the use of this term is misleading. In material science, the term hardness refers to the resistance of a surface to penetration or indentation by a small probe. The term crushing strength is also frequently used to describe the resistance of tablets to the application of a compressive load.

  • Resistance to crushing of tablets WHO

    This test is intended to determine under defined conditions the resistance to crushing of tablets, measured by the force needed to disrupt them by crushing. Apparatus The apparatus consists of 2 jaws facing each other, one of which moves towards the other. The flat surfaces of the jaws are perpendicular to the direction of movement.

  • Effect of moisture and crushing strength on tablet

    The optimum friability corresponding to a granulation moisture content and a tablet crushing strength was a simple minimum. The in vitro dissolution contour plots showed a stationary ridge system. Along the ridge, a large number of combinations of tablet crushing strength and granulation moisture represented 100% drug dissolution.

    Aug 06, 2008· The results were averaged because actual crushing strength measurement is not possible. For example, alignment of the tablet affects the result when conventional crushing strength equipment is used. If it were possible to measure the same tablet many times with the diametral crushing strength apparatus, the result could be different each time.

  • Tablet hardness testing Wikipedia

    Tablet hardness testing, is a oratory technique used by the pharmaceutical industry to determine the breaking point and structural integrity of a tablet and find out how it changes "under conditions of storage, transportation, packaging and handling before usage" The breaking point of a tablet is based on its shape. It is similar to friability testing, but they are not the same thing.
