Protect the integrity of research applications with a tight moisture-barrier that holds a strong seal and doesn’t release from glassware, despite off-gassing. Reduce the risk of tampered data with a covering that is odorless, colorless and semi-transparent. Prevents moisture and volume loss due to material composition and tight seal. Flexible and self-sealing material allows it to cling around irregular shapes and surfaces. Stretches more than 200% of original length. Resistant up to 48 hours against many polar substances such as saline solutions, inorganic acids and alkaline solutions.
