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
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™
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.

VWR®, Black Film Seals for Fluorescence and Photoprotection
Supplier: VWR Collection
These films are 240 µm thick black vinyl with adhesive for use with 96-well, 384-well and 1536-well black microplates. They fit within the edges of raised rim plates and may be applied to either the plate top or bottom. The light blocking and absorbing properties of these films make them ideal for reducing stray light and crosstalk in fluorescence applications and for protecting light-sensitive samples in storage.
