Silicone is the standard laboratory tubing most used for smaller bore sizes to 9.6mm (3/8") bore. This food and medical quality material meets USP and NFS Class VI standards and is autoclavable. Watson-Marlow Bredel also manufactures a
specially-developed platinum-cured silicone tubing called Pumpsil® for additional protection from contamination during the pumping process.
