Product Description
Seal tubes, flasks, beakers and plates quickly against moisture loss and contamination with a film that stretches to fit almost any shape. This flexible, self-sealing laboratory film clings tightly around rims and irregular openings, making it a staple for short-term covering and storage in research, clinical and industrial labs.
This listing is for catalog number HS234526C: Parafilm 100mm x 75m, Natural, Roll. The semi-transparent thermoplastic film is a blend of waxes and polyolefins that stretches to more than 200% of its length with two-way stretch. It is non-toxic and odorless, resists acids, alkalis and organic solvents, and resists saline, inorganic acids and alkaline solutions for up to 48 hours. Rolls are offered in 2, 4 and 20 in. widths, in natural and a purple option. Order it from LIGHT LABS and keep your bench running smoothly.
