Tablet tooling: Don’t let it corroded Corrosion can severely affect tablet compression tooling if it is not addressed effectively. It can delay production, reduce efficiency and cause contamination problems. Corrosion can be detected by the appearance of discoloration, etching or common red rust. The main cause of corrosion is acidic substances, which can include ingredients found within the formulation being compressed and even in the surrounding atmosphere. The iron particles in the metal tooling are exposed to oxygen and moisture in the form of humidity or vapor. When the steel is exposed to water, the iron particles are lost to the water’s acidic electrolytes. This means they oxidize the iron particles, which form corrosion on the punches and dies. There are several reasons why corrosion can occur, and although challenging, it can be resolved with a combination of the correct steel, coating or treatment selection and proper maintenance procedures. Atmospheric moisture One of the pr...

 Following parameters checked during granulation process  1. Angle of repose-  Angle of repose of any solid in pulverized form represent an angle measured in theta,  Angle of repose = tan-¹(2h/d), unit is degree (°) Acceptance =  < 25° = Excellent  25°-30°= Good 30°-40°= Average  >40°= Bad  2. LOD ( Loss on Drying )  Test is designed to measure the amount of water and volatile matters in a sample when the sample is dried under specified conditions eg. 100° C for 5 minutes  Formula  LOD = Initial weight before drying - final weight after drying / initial weight before drying ×100 3. Compressibility index  Measure of the propensity of a powder to be Compressed also known as Carr's index  Formula  Carr's index = true density - bulk density / bulk density ×100 Acceptance  <15% = Good flow  >25% = Poor flow  15%- 25% = Smooth for compression  4. Bulk density and tap density  Bulk densit...

  MONTHLY CALIBRATION OF BALANCES  For monthly Calibration of Balances check following parameters- 1. Accuracy - verify the balance with minimum weight (least count × 100), 5%, 20%, 50%, 90% capacity of respective balance capacity. Tolerance - the variation if any should be ± least count of the balance or ± 0.2% of certified standard weight used whichever is higher    2. Reproducibility -  Check the reproducibility by using minimum standard weight of balance capacity. Place the weight in the middle of the weighing pan observe the displayed value  Then calculate the %RSD by following formula  RSD= SD×100 / X  Where,  X= mean of the individual value Acceptance = %RSD should not be more than 2.0% 3. Eccentricity  Eccentricity is the difference between the weight placed in centre and at peripheral points of the weighing pan
