Seal-R-film Laboratory Film, 50 mm x 75 m je Roll, 24 Rolls/PAK

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. - Thickness: 0.14 +/- 0.02mm
