Genuine Brand OCU-FILM + tip covers protect TONO-PEN brand tonometers from dust and fluids, and help protect patients from the risks of cross contamination. OCU-FILM+ tip covers are 100% hand inspected by trained technicians, individually packaged, and are provided sanitized in polyvinyl pouches. OCU-FILM+ tip covers were carefully developed as an integral part of the design specifications for TONO-PEN instruments to ensure maximum accuracy and reliability. Reichert tip covers are blue in color to help ensure you are using genuine brand OCU-FILM + tip covers. Reichert has an exclusive contract with a quality, validated latex supplier to bring you a tip cover that provides consistent performance and function with each measurement. OCU-FILM+ tip covers are the only manufacturer-approved covers for use with TONO-PEN tonometers. These tip covers are custom made for Reichert and the unique frusto-conical geometry makes OCU-FILM+ tip covers easier to apply to TONO-PEN tonometers. The tip covers also feature a textured surface skin to reduce sticking to itself and the metal transducer tip during application.
