Cleaning Validation and Verification

Three areas of control

Effective cleaning and disinfection, validation end to end.

Effective cleaning and disinfection are essential to preventing microbial contamination, product carryover, and cross-contamination. PlumGXP supports three related areas of control: cleanroom disinfectant efficacy validation, manufacturing equipment cleaning validation, and ongoing cleaning verification.

Our cleaning validation services

Disinfectant efficacy, equipment cleaning validation, and ongoing verification.

We can work from your approved protocol or help develop and execute the entire program.

Disinfectant Efficacy Validation

USP <1072> Hard-surface challenge studies based on applicable USP principles, evaluating representative cleanroom materials against USP challenge organisms and resident environmental isolates recovered from your facility.

Manufacturing CIP

Equipment Cleaning Validation

Demonstrates that an established cleaning procedure consistently removes drug-product residues, active ingredients, excipients, degradation products, and cleaning agents to scientifically justified acceptance limits.
