Swab / Rinse Acceptance Limit Calculator

Purpose: Calculate swab or rinse acceptance limits for cleaning validation based on MACO and equipment surface area.
Enter MACO (Maximum Allowable Carry Over) in mg/batch. Note: If only PDE is known, calculate MACO externally using batch size and maximum daily dose before entering.
Enter Equipment Surface Area (for swab) and Swab Area or Rinse Volume as applicable.
Select Method: Swab or Rinse.
Enter Safety Factor, LOQ, and Recovery (%) for pass/fail evaluation.
Click Calculate to display results in a separate container.
