What is parafilm used for in lab?

Parafilm M® is a moisture-resistant thermoplastic used in research, clinical and industrial laboratories. This laboratory film can be utilized to prevent contamination, evaporation or spills.

Is parafilm used to prevent gas leaks?

Parafilm will prevent moisture and volume loss but it is also permeable to oxygen, carbon dioxide and water vapour. Therefore it allows for off-gassing without compromising the sample integrity.

Is parafilm a paraffin?

Parafilm M Laboratory Film is a paraffin plastic film which typically comes in rolls with square demarcations printed on a paper backing. It is a ductile, malleable, waterproof, odorless, translucent, and cohesive thermoplastic, making it extremely versatile under a number of conditions.

Is parafilm waterproof?

Parafilm M is a semi-transparent, flexible, thermoplastic, and highly waterproof sheet material. The permeability of either oxygen or carbon dioxide should not be affected at different relative humidities because of the low water permeability and insensitivity of Parafilm to moisture vapor.

Why is parafilm used?

Parafilm M® is a moisture-resistant thermoplastic commonly used to seal Nematode Growth Media (NGM) agar plates on which the nematode Caenorhabditis elegans is cultured. This practice reduces media dehydration and microbial contamination.

Does parafilm prevent oxygen?

Parafilm M is a semi-transparent, flexible, thermoplastic film that provides a waterproof barrier for covering laboratory vessels. It is gas permeable with low water permeability. Ideal for use in Microbiology and Cell Culture applications as it does not affect oxygen or carbon dioxide permeability.

Does Parafilm prevent oxygen?

When was Parafilm first used in the lab?

Originally commercialized in the 1930s and intended for map mounting, Parafilm was quickly adopted by lab scientists for a myriad of uses. How is Parafilm used? Parafilm is most commonly used for sealing and protecting vessels such as test tubes, cuvettes, and petri dishes.

How is Parafilm M used in health care?

Parafilm M is commonly used in health care, pharmaceutical and research laboratories for covering or sealing vessels such as flasks, cuvettes, test tubes, beakers, petri dishes and more. Because it melts quickly when heated, Parafilm M is not safe for use in an autoclave. It is also soluble in many organic solvents..
