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®, 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.

VWR®, Adhesive PCR Foil Seals
Supplier: VWR Collection
These soft, non permeable 63,5 µm thick aluminium foils, with strong medical grade adhesive, eliminate the need for heat sealing devices or mats during thermal cycling. Compared to other aluminium foils, these foils have less tendency to roll back on themselves when removing the backing paper, and fit well to the plate during application.

VWR®, Polyester Films with Colour-Coded Marking Areas
Supplier: VWR Collection
Identical to polyester films above, but include a colour dot and white writing area on each end tab for plate identification. End tabs with backing removed adhere to the ends of the plate and are perforated so they can be left in place even if the centre portion of the film is removed. Alternatively, one inscribed colour-coded end tab can be removed and pasted in a laboratory notebook while the other remains on the plate.

VWR®, Breatheable Rayon Film Seals for Biological Cultures
Supplier: VWR Collection
A 139,7 µm thick hydrophobic porous film with medical grade adhesive for tissue culture plates, bio-blocks, and 96-well plates where gas exchange is necessary for cell or bacterial growth. These rayon films minimise cross-contamination, spillage and evaporation. They allow uniform air and CO₂ exchange for all wells, unlike plate lids which favour exchange for wells near plate edges. Sterile product is packed in tamper evident bags of 25.
