- PTFE Teflon Tubing 1/16″ OD x 500µm ID 23G Fitted (10m): PTFE Teflon tubing can handle extremely high temperatures in harsh chemical environments. It is also chemically inert, has low permeability, and the lowest friction coefficient of any tubing. Just like Tygon tubing, Teflon tubing is commonly used to connect microfluidic instruments and microfluidic reservoirs.
However, since PTFE Teflon tubing is non-elastic yet slightly flexible, using stainless steel adapters for connections is trickier than with Tygon tubing, but it is still possible. In any case, direct Tubing-PDMS connections are possible and reliable due to PDMS elasticity, and therefore recommended.
