Cederroth Eye Wash Pocket Model (235mL) is a single-use, sterile, ready to use buffered solution for eye irrigation that can be kept conveniently in your pocket or the holster hat goes with it. It cleanses the eye to help relieve irritation, discomfort, burning, stinging, or itching by removing loose foreign material, air pollutants (smog or pollen) or chlorinated water. It helps restore normal pH levels from corrosive substances (alkalis or acids). The twist-off, tamper proof cap ensures the solution remains sterile until time of use. The integrated eye cup conforms around the eye for comfortable use. Cederroth has a shelf life: 4,5 years.
