The Nunc Sealing Tapes provide an effective seal on polypropylene, polystyrene and polycarbonate MicroWell™ Plates, minimising evaporation and well-to-well cross contamination. Compatible with aqueous solutions and organic solvents, the tapes are also tested for use between -80° and +110° C. A DNAse and RNAse free version is available for thermal cycling applications. Optical clarity allows reading through the tape. All of the tapes are suitable for long-term storage.
