Product Description
Oxygen Permeability Tester for Contact Lenses Materials Based on ISO 9913
Oxygen permeability of contact lenses has a direct influence on wearer comforts and will in turn affect the sales. That is why oxygen permeability testing attracts particular attention of lens manufacturers.
ISO issued special testing standards for the oxygen permeability testing of contact lenses: ISO 9913-1 Optics and Optical Instruments-Contact Lenses-Part 1: Determination of Oxygen Permeability and Transmissibility with the FATT Method and ISO 9913-2 Optics and Optical Instruments -Contact Lenses-Part2: Determination of Oxygen Permeability and Transmissibility by the Coulometric Method. Testing principal and testing instruments in ISO 9913-2 is very similar to that used in coulometric method in oxygen permeability testing of flexible material. Many manufacturers of contact lens have been authorizing Labthink to test the oxygen permeability of lens materials and have got ideal testing results.
OX2/231 Oxygen Permeability Tester can be used for contact lense testing.
