TWIRL'EM® sample bags, sterile - Polyethylene (PE-LD)

Transparent, 0.07 mm thick with double base seam and plastic covered wire closure. The bags are sterile (sterilised with gamma radiation) and sealed at the top. Opening is done easily by tearing the perforated edge, thus ensuring sterility until used. The wire closure can easily be pulled apart to produce a dimensionally stable opening for filling. Particularly suitable for the collection, storage and transportation of solids, powders, granulates, samples, liquids, etc. To achieve an airtight seal, the wires are pressed together, the top of the bag is rolled four to five times and the end bands are bent into the centre (not recommended for the transportation of liquids).
