14.2 Process wetted materials
Materials used
The materials used in the manufacturing of ÄKTA ready have been chosen for their bio-
logical and chemical compatibility with the solvents used during operation. The system
has also been designed to comply with the varying hygienic requirements at the different
stages of development and production. The flow kit tubing has been treated with gamma
radiation, except for the pump tubing, which has been autoclaved (the pH electrode has
not been treated).
