A variety of seals for the protection of lab samples from contamination are available at VWR. Secure microplate samples with films, foils, and sealing tapes; select products appropriate for ELISA, PCR, cold storage, and general incubation. Sealing mats minimize evaporation and eliminate cross-contamination. For beakers, flasks, petri dishes and other labware, choose sealing films that are heat or chemical resistant. Insure sample integrity with security seals that provide evidence of tampering. Mechanical seals are also offered.
