Product Code: 52858
MPN: PM996
PARAFILM® M Laboratory Film, 4" × 125' Roll is the industry-standard flexible sealing film used in research, clinical, pharmaceutical, environmental, and quality control laboratories. Manufactured from a proprietary thermoplastic blend of polyolefins and paraffin waxes, PARAFILM M creates a moisture-resistant, self-sealing barrier that helps prevent sample evaporation, contamination, and spills. The film stretches easily around irregular surfaces, forming a secure seal on laboratory glassware and plasticware without adhesives.
- Forms an effective moisture and contamination barrier to help preserve sample integrity.
- Self-sealing without adhesives, tapes, or fasteners.
- Stretches 200–300% to conform tightly around irregular shapes and vessel openings.
- Helps reduce evaporation from culture tubes, flasks, beakers, Petri dishes, bottles, and microplates.
- Resistant to water, saline solutions, many acids, alkalis, and some organic solvents for typical laboratory exposure.
- Flexible, odorless, latex-free material that leaves minimal residue after removal.
- Easily cut to the desired length using the convenient dispenser box.
