Mechanical Seals
A variety of seals for the protection of lab samples from contamination are available at Avantor. 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.

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.
