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.

Adhesive seal, AMPLIseal™

Adhesive seal, AMPLIseal™

Supplier: Greiner Bio-One

AMPLIseal™ is a self-adhesive sealing film notable for its low autofluorescence, in particular in the wavelength range critical for Real Time PCR. It consists of a thick PP film coated with a transparent acrylate adhesive. The adhesive layer is protected by a peelable polyester film. The strongly adhering acrylate adhesive provides reliable sealing, thereby minimising evaporation but without influencing the PCR reaction or the fluorescence measurement.

Dual Vespel® ring inlet seals

Dual Vespel® ring inlet seals

Supplier: Restek

A ring inlet seal greatly improves injection port performance as it stays sealed even after repeated temperature cycles, without retightening the reducing nut. This seal features two soft Vespel® rings, one embedded in its top surface and the other embedded in its bottom surface. These rings eliminate the need for a washer and ensure very little torque is needed to make a leak-tight seal.
