Cleaning validation: limits, sampling plans and verification records.
Keep your cleaning limits, sampling plans and results together.
PDE / HBEL-based MACO calculation
Per EMA 2014 guideline: MACO from PDE, batch size, shared surface area, sampling recovery — recalculated automatically whenever any input changes.
Living Worst-Case Matrix
Products ranked by hazard × solubility × dosage × cleaning difficulty; the matrix refreshes on every new SKU introduction and flags if the worst case…
Sampling Plan Generator
Swab locations mapped to equipment CAD; rinse volumes, recovery studies, blank controls calculated per protocol.
What goes wrong today3 common problems
MACO Calculated Once, Never Updated
A new product enters the shared train and nobody recalculates the limit. The old MACO is now non-conservative and the auditor spots it.
Worst-Case Matrix on Paper
Solubility, toxicity, dosage strength ranked in a locked spreadsheet from 2019. Three product launches later, the ranking is wrong.
Swab Results Live in QC, MACO in Engineering
The result never gets compared to the current limit at the moment of release — it happens once a year at revalidation.

PDE / HBEL-based MACO calculation
Per EMA 2014 guideline: MACO from PDE, batch size, shared surface area, sampling recovery — recalculated automatically whenever any input changes.
Living Worst-Case Matrix
Products ranked by hazard × solubility × dosage × cleaning difficulty; the matrix refreshes on every new SKU introduction and flags if the worst case has shifted.
Sampling Plan Generator
Swab locations mapped to equipment CAD; rinse volumes, recovery studies, blank controls calculated per protocol.
Real-time result → MACO comparison
Every swab and rinse result compared to the live MACO; a failure holds the equipment before the next campaign starts.
Continuous cleaning verification (Annex 15)
Post-validation verification cycle scheduled, executed, and trended — evidence that the validated state is maintained.
How it works, step by step5 steps
Cleaning validation in V5.
- PDE/HBEL captured. Sourced values captured with expert signoff.
- Matrix Built. Product-equipment worst-case identified.
- Sampling & Method. Locations, recoveries, methods under control.
- Validation runs. Results captured with signed effectiveness.
- Ongoing CCV. Live trend; excursion opens investigation.
What to look for when choosing
Cleaning validation moved to HBEL/PDE with EMA guidance and ICH Q3D toxicology. Spreadsheets that still use 1/1000-dose don't survive the audit.
HBEL/PDE Calculation
Are limits driven by PDE/HBEL toxicology with sourced data? PDE/HBEL native; sourced toxicology captured with the calculation.
MACO with Worst-Case Matrix
Are MACO calcs product-by-product with a worst-case matrix? MACO computed per product-equipment pair; worst-case matrix visible.
Sampling Plan
Are swab and rinse locations, recoveries and analytical methods captured? Sampling plan under change control; recoveries versioned.
Dedicated vs Shared Equipment
Does the model distinguish dedicated and shared paths? Equipment tagged; dedicated paths excluded from shared MACO.
Continuous Cleaning Verification
Is CCV data captured and trended? CCV native with trend per equipment.

Common questions3 answers
- Does V5 support HBEL / PDE per the EMA 2014 guideline?
- Yes. PDE is entered per active with the toxicological rationale attached; MACO is derived from PDE, shared surface area, batch size and recovery factor per the current EMA methodology.
- How does V5 handle dedicated vs. shared equipment?
- Equipment is tagged as dedicated, shared or campaign; the worst-case matrix and MACO calculation apply only to shared trains and campaign changeovers.
- Can V5 integrate with our TOC analyser and HPLC?
- Yes — direct instrument integration or via LIMS. Swab and rinse results flow in with instrument ID, analyst, method version and calibration status.
