Product Description
Seal flasks, tubes and beakers with a film that holds up where wax-based films soften and fail. DuraSeal™ stretches into a tight, waterproof closure in seconds and stays put through boiling water baths and solvent exposure.
This listing is for Diversified Biotech catalog number DS4-250, the DuraSeal™ Laboratory Sealing Film Roll. DuraSeal™ is a 1.5 mil LDPE stretch film made without adhesives, so it resists nearly all caustic agents and organic solvents and is microwave compatible. With no interleaf paper to peel, the film is simply stretched over an opening, where it contracts and clings to itself; it can elongate 500-800% before breaking. Rolls come in several widths and lengths, and matching Dura Shears give clean, sharp cuts. Add it to your LIGHT LABS order and keep your bench organized and samples identified.
Key Features
- Heat Resistant – Withstands incubation in boiling water baths without the melting typical of paraffin-based films
- Chemically Resistant – Adhesive-free polyethylene resists essentially all caustic agents and organic solvents
- Drum-Tight Seal – 1.5 mil film contracts around the container opening or neck to form a waterproof seal
- Tear Resistant – Elongates 500-800% before breaking, reducing tears while stretch sealing
