Laboratory Applications
These snap caps close blood collection tubes, sample vials, and general test tubes in the 12/13mm range. Phlebotomy stations, clinical chemistry labs, and microbiology departments rely on color-coded closures to keep specimens segregated through transport and centrifugation.
Research and teaching labs use disposable PE caps to seal reagent and sample tubes during prep and short-term storage. Hand-applied snap fit suits fast-paced settings where many tubes are capped per run, reducing handling time without sacrificing closure security.
