laboratory parafilm
Laboratory parafilm is an essential laboratory supply that serves as a versatile sealing material, combining flexibility, durability, and chemical resistance. This self-sealing, moldable material is composed of a blend of paraffin wax and polyolefins, creating a waterproof and semi-transparent barrier that has become indispensable in laboratory settings worldwide. The film stretches up to 200% of its original length while maintaining its integrity and creating an airtight seal. It effectively protects containers from contamination, prevents evaporation of volatile substances, and helps maintain sample integrity. Its unique composition allows it to adhere to most laboratory surfaces, including glass, plastic, and metal, without leaving residue upon removal. The material remains stable across a wide temperature range, typically from -45°C to 50°C, making it suitable for both refrigeration and moderate heat exposure. Modern laboratory parafilm features enhanced chemical resistance, protecting against most acids, alkalis, and solutions commonly used in laboratory procedures. Its moldable nature enables it to conform to irregular shapes and surfaces, ensuring reliable sealing for various container types, from test tubes to beakers and flasks.
