Parafilm’s primary purpose is to prevent evaporation and contamination when sealing up agar petri-dish plates and test tubes. Its unique permeability and water vapour transport properties has made it an essential one of a kind laboratory consumable for professional cultivators and lab technicians world wide.

Parafilm is self-sealing, transparent, flexible and moisture-resistant. A paraffin based thermoplastic which can stretch up to 200% its original size to provide a breathable yet reliable waterproof barrier to protect your cultures against contaminants.

Interlined with backing paper to prevent sticking, a small amount of Parafilm goes a long way.

To use cut your parafilm into 1cm strips, peel the backing off one edge of your film and stretch around the plate. Once completely wrapped simply pull and rip off the remaining film and save for later. Parafilm will adhere to itself so ensure the remaining part of film is secured to the dish.
