Solvent Resistant Peelable Heat Seal Arvensis

• Very high solvent resistance to DMSO and other organic solvents
• Suitable for long term sample storage, especially compounds stored in DMSO
• Strong yet peelable seal to PP and COC plates
• Forms permanent bond to PE plates
• Seal integrity: -80°C to 40°C
• Certified free from DNase, RNase, nucleases and human gDNA

Solvent Resistant Peelable Heat Seal is an aluminum foil that forms an excellent peelable seal to plates made from polypropylene and cyclic olefin copolymer. This material forms a permanent bond to polyethylene plates and cannot be peeled off. For polyethylene plates, sample retrieval can be done by piercing the foil with a blade, needle, or other seal piercing tool. The outstanding solvent resistance of this seal supports its use for low temperature and ambient temperature compound storage in DMSO and other organic solvents. Our own testing has shown that 100% DMSO can be stored at ambient temperature for 12 months without sample loss or deterioration of the seal.
