Description

Parafilm M, 4 IN. x 125 FT  

YEAR END PROMOTION TILL 31 DECEMBER 2021

 

Efficient and cost-effective covering for test tubes, beakers, vials, petri dishes, flasks, and various other instruments and objects with irregular surfaces.

 

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
