Diversified Biotech HEADS4-250 DuraSeal Durable, Heat-Resistant, Solvent-Proof Laboratory Sealing Film, Clear, 4 x 3000" (4" x 250')

Features:

• Durable, heat-resistant, solvent-proof laboratory sealing film
• Chemically resistant Heat resistant & Microwave compatible
• Tight sealing
• Tear resistant DuraSeal the durable, heat and solvent-resistant LDPE stretch film, has substantial advantages over common laboratory stretch films.
• Its' superior heat-resistant feature allows for containers to be incubated in boiling water baths without suffering the characteristic melting of paraffin-based alternatives.
• Since DuraSeal is polyethylene based and free of any adhesives, it resists essentially all caustic agents and organic solvents.
• DuraSeal is easy to use.
• There is no inter-leaf paper to strip away, just stretch the film symmetrically over a container opening and the 1.5 mil thick film contracts inwardly around the opening or neck of the container to provide a drum-tight, water-proof seal.
• The film can be elongated 500-800% before breakage, minimizing the incidence of tearing during stretch sealing.
• The film clings to itself, especially after stretching so the free edges of the film may be stretched around the container to secure the container edges.
