what is parafilm for
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.
We use the parafilm to adhere thin strip of solder which has been cut from a solder bar. The solder consists of either Tin/Copper or Tin/Lead/Silver. Does the parafilm in any way interact with the above composition of the solder? We plan to store the parafilm with the adhered solder strip until it is time to cut solder preforms from it, then we will discard the parafilm. As per the specification datasheet provided by Cole-Parmer, PARAFILMÂ® M can be stored for at least 3 years without loss of quality under storage condition between 7 Â°C and 32 Â°C and a relative humidity of 50%.
