This thick-walled platinum-cure silicone tubing is used in the tube sets for Instech peristaltic pumps, including those in our Automated Blood Sampler. 015 is the standard used for mouse ABS tube sets, 020 for rats and 031 for large animals. The wall thickness for all sizes is 1/32in (0.031in or 0.8mm).
As of January 2019, Instech no longer sells intravascular silicone tubing in 2-7Fr sizes. Polyurethane is preferred for most applications.
