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.

Adhesive film seals for microplates, SecureSeal™
Supplier: Simport Scientific
Adhesive sealing films reduce sample-to-sample or well-to-well contamination and/or spill over. SecureSeal™ has the differential advantage of perforated end tabs and a multiple split backing which allow for easier and more accurate positioning and more secure sealing. The polyester based film with acrylic adhesive is inert and thus compatible with almost all microplate procedures. SecureSeal™ is less than 0,001% moisture permeable under high humidity conditions and less than 0,01% oxygen permeable.
