Cleanroom Wipes for Pharmaceuticals: Pyrogen Testing Methods
Cleanroom wipes and gloves undergo LAL and Agar Overlay Analysis when testing for pyrogen and endotoxin levels. This post details the methodology, historical relevance, and explores cleanroom solutions for pyrogen-free and low-endotoxin gloves and garments.
Particulate and Molecular Contamination Tests for Cleanroom Wipes and Fibers
The majority of wiper contamination tests probe for particles, fibers, ions, nonvolatile residue, and bio-contaminants. Cleanroom wipe test methods detail and measure the extraction and enumeration particles, fibers, and other contamination released from wipers (or other materials), usually in a wetted state, under conditions of moderate mechanical stress.
Cleanroom Wipe Contamination Profiles for Medical Device Wipedown & Electronics
The ideal cleanroom wipe must meet industrial and regulatory standards concerning chemical, physical, and biological compatibility. Wipe fabrics undergo a strict examination to simulate manufacturing outcomes in the real world.
Stretch and strength, chemical compatibility, task efficiency, sorbency, shed, retention, and biological harmony have unique consequences in both high-tech cleanrooms and general manufacturing floors.
Cleanroom Wipe Testing Standards for ASTM, IEST & ISO Organizations
ISO cleanroom wipe classification is important, but is it enough? A clean room wipe selection criteria should meet baseline particulate shed thresholds for the end-user environment. Like any cleanroom rated product, cleanroom wipe manufacturers qualify ISO wipers between ISO Class 1 – ISO Class 9 as specified in step with cleanroom classifications of the International Standards Organization (ISO). The majority of cleanroom classifications fall between ISO 5 – ISO 8.
