Film and Foil Wrapping
Chemglass Life Sciences Chemglass Parafilm M sealing film, 2 in x 250 ft roll, 1 roll
Parafilm M sealing film provides a flexible, moisture-proof, self-adhering barrier for sealing laboratory glassware and containers. Supplied as a 2 in x 250 ft roll, it conforms to irregular shapes to reduce evaporation and contamination in sample handling applications.
- Flexible, semi-transparent thermoplastic film that molds to surfaces.
- Roll dimensions: 2 in x 250 ft; one roll per pack.
- Stretches more than 200% for secure seals around irregular shapes.
- Resistant to many acids, alkalis, and some organic solvents.
- Not recommended for use with acetone, diethyl ether, or tetrachloride.
Research Products International Corp Flexible Lead Foil, .030 Inches Thick, 14 Inches Wide, 5 Feet Long
Flexible lead foil is ideal for wrapping around tubes, bottles or containers that require shielding from 125I. Clean and easy to use lead foil can be cut with a utility knife or scissors.
Chemglass Life Sciences DuraSeal Stretch Film, 2" x 500'
DuraSeal Stretch Film, 2" x 500'. DuraSeal the durable, heat and solvent-resistant 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. Permeability Information:Oxygen = 125cc/100in2/24hrs at 23C. Carbon Dioxide = 1300cc/100in2/24hrs at 23C. Water Vapor = 1.0g/100in2/24hrs at 38C and 90% R.H. (vs a desiccant on opposite surface)

Research Products International Corp Parafilm M Laboratory Sealing Film, 2 inch x 250 foot Roll
Parafilm M is a semi-transparent, flexible, thermoplastic film that provides a waterproof barrier for covering laboratory vessels. It is gas permeable with low water permeability. Ideal for use in Microbiology and Cell Culture applications as it does not affect oxygen or carbon dioxide permeability. Nontoxic material is resistant to acids, alkalis, alcohols and organic solvents.
