No more spilling, evaporation, and contamination! Seal-R-film™ sealing film seals beakers, flasks, and other vessels. The sealing film can be stretched to three times its original length. This means that Seal-R-film™ always fits, even with irregular shapes. For traceability, each roll has a lot identification.
