Radel® R
Radel® R (polyphenylsulfone) tubing offers very high burst pressure and good chemical compatibility. This amorphous polymer can withstand repeated autoclave sterilization cycles because of its excellent thermal properties. Our Radel tubing is transparent, making visual monitoring of flow possible in high-pressure tubing. Chemicals that react with Radel are not pH dependent, please consult the chemical compatibility section of the website for more information on specific chemicals.
