General description
PARAFILM stretches up to 200% and clings even around irregular shapes and surfaces. The sealing film is free of plasticizers and consists primarily of polyolefins and paraffin waxes. PARAFILM M is resistant up to 48 hours against many polar substances, eg saline solutions, inorganic acids and alkaline solutions.
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

The peripheral circadian clock in mice is entrained not only by light-dark cycles but also by daily restricted feeding schedules. Behavioral and cell culture experiments suggest an increase in glucose level as a factor in such feeding-induced entrainment. For application

I'm designing an experiment which involves using Parafilm M as a coverslip for a bacterial culture. Therefore, I need it to sterilize it previously. Which methods are suitable for this process? Thank you!

Ich habe immer Parafilm M. (Bemis 12) genutzt. Nun habe ich die einzelnen Strips hier, und man kann das Trägerpapier nicht ablösen; zumindest weiß ich nicht wie. Gibt es da einen Trick oder klebt die Folie nach 3 Jahren einfach fest auf dem Träger?

Parafilm is generally very stable. the temperature range for continuous use is -45 to 50 deg. C. Storage at or excursion beyond this range may impact the physical properties making it difficult to use and possibly separate from the backing. Some tips to separate from the backing include rubbing between fingers, creasing or trying to tear an edge or corner, scraping or marking with a micro spatula or other firm edged item. Below see the general use video on Parafilm that uses the creasing method.
