Parafilm is ideal for the scientific laboratory because it is a thermoplastic, self-sealing film. It holds moisture loss to a minimum. It offers excellent protection for the contents of tubes, flasks, and petri dishes.
Biofilm Removal. Biofilm is a substance that forms readily in water distribution lines, water storage tanks, and any. other aqueous environment. A Biofilm forms when bacteria begin to excrete a slimy, sticky. substance that allows them to adhere to surfaces. The biofilm mass usually consists of many. species of bacteria, and can also include fungi, algae, and protozoa. Biofilm is resistant to chlorine. and is difficult to remove once initial adhesion occurs.
