Why Particle Counter Selection Is the First Engineering Decision in a New Cleanroom If you walk into a newly built cleanroom and ask “is this room actually clean?”, the only honest answer comes from a particle counter. Not a smoke…
For sterile manufacturers, environmental monitoring (EM) is the evidence that a facility can repeatedly produce product in a controlled state. The revised EU GMP Annex 1, published in August 2022 and applicable since 25 August 2023, tightened expectations across the…
When a new cleanroom is handed over, construction may be finished — but the facility is not yet qualified. Qualification is not a single test or a one-time inspection. It is a structured, documented process that proves a cleanroom performs…
ISO 14644-1 Cleanroom Classification: Particle Count Limits & How to Verify Them A cleanroom’s ISO class is not a design claim; it is a measured result, verified with a calibrated particle counter following ISO 14644-1. A failed classification can delay…
GMP Environmental Monitoring: What, Where, and How Often to Sample Environmental monitoring is the backbone of aseptic manufacturing. Under GMP, it is the systematic sampling and testing of air, surfaces, and personnel that proves a cleanroom remains within defined limits…
Cleanroom environmental monitoring is a critical component of pharmaceutical manufacturing compliance. Selecting the right airborne particle counter ensures your facility meets EU GMP Annex 1, FDA 21 CFR Part 11, and ISO 14644-1 standards. This guide outlines the key considerations…
