Storage, Cleaning & Sterilization Procedures

Storage, Cleaning & Sterilization Procedures


Storing Tygon tubing is simple and presents no unusual problems. Whenever possible, it is desirable to store the tubing in a carton or box to eliminate or minimize its collecting dust. It is a good idea to dry store the tubing after cleaning, with ends open to permit thorough drying. If it is impossible to store Tygon tubing in cartons, place it loosely coiled or laid out straight on a clean dry shelf, free from contact with painted surfaces, rubber, oils and greases. In any case, avoid kinking by not hanging the tubing over a nail or sharp edge.


Generally, cleaning Tygon tubing is as simple as the flushing of the bore with soap and water, followed by a clear water rinse. Its low surface tension facilitates complete drainage. In addition, Tygon tubing will withstand virtually all commercial cleaning agents and bactericides without danger of corrosion (as with metals) or oxidation (as with rubber). When using these preparations, do not increase the temperature or the concentration of the solution beyond that recommended by the manufacturer. If the tubing shows excessive swelling during cleaning, reduce pressure and temperature. Contact with paint, rubber, oils, greases, hand creams and perspiration, or prolonged exposure to strong sunlight will also affect clarity. Certain strong sanitizing agents, such as those containing iodine or bromine, also have a tendency to cause some staining. However, these are surface discolorations and in no way affect the performance or life of the tubing. After exposure to moisture, a slight cloudiness will be noted. This is simply a surface film of moisture, and clarity will return shortly if the tubing is allowed to dry and air thoroughly.


Listed to the right are commonly used methods of sterilization and tubing compatibility. It is required that the user conduct tests using the conditions of the application prior to specifying a particular tubing formulation.
