When we take a tablet as medicine it looks quite good in shape and shining colors but whether it will affect good or not depends on its disintegration properties. Disintegration means releasing drug content in the body on oral consumption. A disintegration test is usually done for checking the tablet or capsule’s disintegration properties. To carry out this test disintegration test apparatus is used. This is a simple mechanical apparatus where two baskets move vertically in a water-filled vessel. The tablet in testing is kept in the cavities of the basket. The motive of this test is to know the dissolving ability of the tablet or capsule intended to use. If a tablet failed to this test that will not able to release its whole drug content in the stomach which will lead it to substandard medicine. The test is carried out as per individual monograph or according to the SOP of Disintegration test apparatus.
