Product Information

A Gas permeable, moisture resistant clear film, available with 24, 96, or 384 optically clear windows; is peelable and sterile*

This unique seal has optically clear adhesive free windows. These windows can be imaged through, and also allow for gas exchange. The clear film is made of a porous material which allows for a uniform air and CO₂ exchange, whilst acting as a moisture barrier and preventing evaporation.

The seal is coated with a strong adhesive (except for the optical windows) which has a high sealing integrity. This ensures a reliable seal and prevention of well-to-well contamination. The gas permeable seal enables long term incubations without intervention, whilst allowing for imaging through the optically clear windows. This can reduce the risk of sample contamination, evaporation and can improve your experimental workflow.

Use of this seal within plate readers can prevent moisture release into the sensitive equipment. A number of plate reader manufacturers recommend the use of the 4titude® Gas Permeable Imaging Seal (Gas Permeable Moisture Barrier Seal).

For all adhesive seals, the best sealing results are achieved using the hand held Adhesive Seal Roller (4ti-0502).
