Perform Dissolution Stage Testing Accurately and Instantly

The validated Excel add-in for pharmaceutical scientists. Automate your dissolution analytics without learning new software or compromising data security.

Evaluating USP <711> stage testing manually in an Excel sheet looks straightforward. In practice, there are at least four ways to get the wrong answer:

  • Wrong Criteria: Applying Q instead of Q+5% at S1, or skipping the individual-unit limits (Q−15% and Q−25%) at S2 and S3.

  • Averaging Errors: Averaging only the newly tested units instead of all 12 units at S2 or all 24 units at S3.

  • Missed Units: With up to 24 units across three stages, one failing replicate is easy to overlook when you’re checking every value by eye, and a single unit below the limit can change the outcome of the entire test.

  • Blind Spots: No built-in logic for when to stop or advance to the next stage

Stop checking every unit by hand.

Perform dissolution stage testing in a fraction of the time. Watch how it works:
