Seals

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.

VWR®, Adhesive PCR Film Seals

VWR®, Adhesive PCR Film Seals

Supplier: VWR Collection

These heat resistant 74,9 µm thick films are designed for thermal cycling applications. Polypropylene films are not pierceable. For PCR applications, where piercing with pipette tips or robotic probes is required for product recovery, use aluminium foil films. For real-time PCR applications, where maximum optical clarity is required, use optically-clear polyester films.

Adhesive film seals for microplates, SecureSeal™

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.
