WKM 2 inch Width x 250 feet Length Thermoplastic Parafilm M Self Sealing Film KTN87 is a widely used self-sealing film in laboratories, offering a versatile and effective solution for sealing various vessels and containers. It is made from a semi-transparent, flexible, and stretchable material called polyethylene and is commonly found in molecular biology, microbiology, and other research and experimental settings.
The main purpose of Parafilm M is to provide an airtight and moisture-resistant seal for a wide range of laboratory equipment, including test tubes, petri dishes, microplates, flasks, and other containers. Its unique properties allow it to conform tightly to irregular surfaces, ensuring a secure closure without the need for additional adhesive or specialized equipment.
Using Parafilm M is straightforward: the user tears off a section of the film, stretches it slightly, and then wraps it around the top of the container. As the film cools, it forms a snug and tight seal. Similarly, it can be easily removed and resealed without leaving any residue, making it a convenient choice for repetitive sealing tasks.
The self-sealing capabilities of Parafilm M are particularly beneficial in various laboratory applications. It acts as a barrier to prevent contamination from dust, microorganisms, and other external pollutants, protecting sensitive samples and cultures. Additionally, it helps maintain a controlled environment by retaining moisture and preventing evaporation, making it ideal for cell culture work and long-term storage.
Parafilm M is also commonly used in molecular biology techniques, such as PCR (Polymerase Chain Reaction), to minimize the risk of cross-contamination between samples. In this context, it acts as a protective barrier to prevent aerosols and droplets from escaping, reducing the potential for experimental errors.
Apart from its sealing properties, Parafilm M can be employed for other applications. For instance, it can be used to temporarily cover microscope slides or cover slips to prevent evaporation during imaging or staining procedures.
Overall, Parafilm M is a versatile and reliable self-sealing film that has become an essential tool in laboratories worldwide. Its cost-effectiveness, ease of use, and adaptability to various vessels and surfaces make it a valuable addition to any laboratory setting, contributing to the maintenance of sample integrity, experimental reproducibility, and overall efficiency in scientific research and experimentation.
