Parafilm M Sealing Film-W50mm L75m

Parafilm M provides a flexible sealing solution trusted in laboratories worldwide. This 75 m × 5 cm format delivers extended length in a narrower width ideal for high-volume labs requiring efficient sealing across multiple items.

Manufactured from polyolefins and paraffin waxes Parafilm M combines elasticity with chemical resistance. It adheres to glass plastic and metal labware providing a protective barrier against evaporation and contamination. With a service temperature range from –45 ºC to +50 ºC (melting point +60 ºC) it performs reliably in routine laboratory environments. The film is resistant to saline solutions most common inorganic acids and bases and solvents such as methanol ethanol and 2-propanol. It is not resistant to diethyl ether chloroform carbon tetrachloride benzene or toluene.
