High optical clarity and low auto-fluorescence make this polyolefin film ideal for real-time qPCR and protein crystallography. The pressure-activated, silicone adhesive provides an extremely strong seal to polypropylene plates which minimizes evaporation, and also makes this film an excellent choice for long-term compound storage and HPLC. Chemically resistant to DMSO, acetonitrile and methanol. The pressure-sensitive, non-tacky adhesive simplifies handling prior to sealing and makes this film ideal for dry samples (e.g. soil, seeds, insects). Universal fit for use with both flat-top and raised-rim polypropylene plates; as well as, polystyrene protein crystallography plates. Features two end-tabs with perforations for ease of handling, application and removal. Certified DNase- & RNase- free
