3. Why to validate?Why to validate?
Equipment validation is Vital for-
• Safety.
• Fewer interruptions of work.
• Lower repair costs.
• Elimination of premature replacement.
• Less standby equipment.
• Identification of high maintenance cost.
• Reduction of variation in results.
• Greater confidence in the reliability of results.

6. IntroductionIntroduction
 Validation of Dry Powder
Mixers
It is defined as documented act
which provide the high degree of
the assurance that Powder Mixer
equipment actually leads to the
desired mixing or blending.
 Why it is essential ?
The mixing of the API and
excipients is the critical step in
the solid dosage form
preparations that affect the
content uniformity at great extent.
