Sealing film Seal-R-film^®

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. With the BRAND cutter for sealing film you can cut rolls with widths of 50 and 100 mm efficiently and economically and store them cleanly.
