Use them for bag and container identification, disposable labware labeling, staging and WIP tags, and documentation support tasks where technicians need a fast-drying, alcohol-resistant mark that can hold up to normal handling and wipe-down discipline. \u003cbr\u003e\u003cbr\u003eSOSCleanroom (SOS) has been a proud distributor of Micronova for over 15 years supporting critical environments.
