Hydrophilic adhesive films


Hydrophillic films
tesa® hydrophilic films are especially designed for use as a top tape to secure fluid flow in capillary cell biosensors.

They consist of transparent PET films functionalized on one side with a non-adhesive hydrophilic coating. Thicknesses between 50 and 250 µm are available to match your target design.
Low contact angle for optimal wettability
