AlumaSeal CS™ Sealing Film for Cold Storage AlumaSeal CS™ sealing films are specially formulated aluminum foil sealing films with an adhesive that withstands cold storage at temperatures to -80°C. Unlike other sealing films in the AlumaSeal group, AlumaSeal CS™ sealing films are not recommended for PCR or thermocycling. A single non-perforated end tab simplifies application. Simply hold the tab and strip the backing from the body of the sealing film as it lays on the plate to avoid curling. • Recommended temperature range: -80°C to +130°C • Certified DNase-, RNase-, and nucleic-acid-free • Excellent barrier properties to retard evaporation • Easily pierceable with pipet tips or robotic probes for sample recovery
