A prep pad looks simple, but its performance rests on a chain of controls that runs from raw material to final release. This series walks through that chain the way our own quality system does — one link at a time. Start with Chapter 1 for the big picture, then follow the chapters in order or jump to the topic you need.
-
1The 4 Critical Quality Attributes of an Alcohol Prep PadConcentration, fluid volume, seal integrity and kill efficacy — why they stand or fall together.
2Why 75% Alcohol — and How We Keep It ThereThe science of 75% ethanol and how compounding and in-line checks hold concentration in spec.
3Proven to Kill: Bactericidal Efficacy ValidationKill-log targets, test organisms and contact times that prove the pad works.
4From Nonwoven to Pharma-Grade Alcohol: Material ControlIncoming specs, supplier qualification and why we screen for optical brighteners.
5Inside Our Production ProcessWater, compounding, metered filling, sealing and leak testing, step by step.
63-Tier Inspection & Batch ReleaseIncoming, in-process and finished-lot testing, COA per lot and retention samples.
7Seal Integrity & Shelf LifeVacuum leak testing, barrier film and how a weak seal quietly fails the whole pad.
8Traceability, Calibration & ComplianceBatch records from raw-material lot to shipment, calibrated instruments and ISO 13485.
