ILP Polyolefin Sealing Film 

• Optical Seal Adhesive Sealing Film
• Polyolefin 2.8 mil Ultra-clear for qPCR
• 50 Films/Pack, 10 Packs/Case 

Incredible optical clarity, non-absorbing, and non-fluorescing properties of these films make them ideally suited for Real Time PCR (qPCR) and optical assay work. Featuring an inert, ultra-clear, and strong encapsulated silicone adhesive that provides extraordinary performance in demanding applications.

Encapsulated silicone greatly reduces the risk of sample contamination due to exposure to adhesive. Once the film is pressed onto the plate, the raised portion of the well penetrates the encapsulation, and a tight seal is formed on just that surface (not over the sample). This silicone seal adheres aggressively, preventing evaporation and lessening the possibility of “Edge Effect”.

The plasticized backing of this film is scored on both ends to allow for two-handed (precise) placement on the plate. Both film and adhesive maintain incredible clarity and are the choice for highly demanding manual and automated processes.

ContainerSeal™ Sealing Tape

ContainerSeal™ is a sealing tape designed for the vast range of bottles and containers used in laboratory applications. Its unique elastomeric characteristics allow it to stretch and conform around the irregular perimeters of containers lids and covers to form a tight seal. ContainerSeal™ will block water vapor loss, reduce the rate of gas exchange and prevent the entry of contaminants and can be easily removed from most surfaces without leaving adhesive residue.
