Tygon® SI (Tygon 3350 Platinum) tubing is a special silicone-based tubing that undergoes a special treatment with platinum to ensure a very smooth internal surface. This surface feature helps improve the material’s use with biological applications where solid material may be present. Additionally, the material exhibits a low-level of protein-binding as well as being non-toxic, helping to make this material the top choice for many life science applications.   Tygon SI 3350 is available in continous length on reels of 15m as well as stopper tubing for peristalitc pumps.
