Parafilm tape for petri dish LABSELECT PM996

Parafilm M Laboratory Film Dish PM996 Petri Dish Tape Liquor Perfume Film Volatile Sealing Film Semi-Transparent,4IN. X 125FT.

Parafilm M Parafilm is widely used in medical, pharmaceutical and research laboratory applications. Parafilm M laboratory sealing film is easy to use, flexible in application, self-sealing, tightly locks in moisture, and provides optimal protection for the contents of test tubes, beakers, culture bottles and petri dishes.

features

It has excellent sealing performance, provides a good barrier, is breathable and impervious to water, and protects the integrity of the sample environment in research applications.

Odorless, colorless, translucent material, reducing the risk of polluting samples and affecting data.

Special material formula, good sealing, prevent sample moisture and volume loss.

The flexible self-sealing material can be attached to various irregular shapes and surfaces, and can be stretched over 200% of its original length.

Can withstand solutions of various polar substances such as inorganic salts, acids, and alkalis, up to 48 hours.
