Description

Description

  • 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.
