PVC “Sensitivity” Upgrade

We live in a very “chemical world” and completely understand that some people are more sensitive to chemicals than others.  All of our machines are built to extremely high standards and specifications, using medical-grade tubing based upon flexible PVC chemistry.  We have had wonderful results through the years with this level of purity.  However, if you are someone who is sensitive to this chemistry, ordering this upgrade will remove all medical-grade flexible PVC tubing from the system, and upgrade it to flexible Tygon 2475 High Purity Tubing or Silicone tubing.
