Most Popular Polymeric Tubing | Low Pressure Zones | PTFE.
Use low pressure tubing on all HPLC systems; before the injector, after the detector, on mobile phase inlet tubing and “to waste” tubing. Low pressure tubing is also used for low pressure LC systems where chemical inertness is desired. All MicroSolv™ low pressure tubing is pure and chemically inert. We offer 4 different types for your specific needs.
PTFE (Polytetrafluoroethylene) commonly called Teflon™ is our lowest cost plastic or polymeric tubing and is widely used in all low-pressure laboratory applications. Our PTFE Tubing is extruded from a fine fluoroplastic resin (641XTX) that has non-aging characteristics, exceptional dielectric properties which is stable with frequency and temperature, a low coefficient of friction and negligible moisture absorption.
Temperature limits are 260°C (500°F) and -240°C (-400°F).
Specification tolerances for 1/16th OD is +/- 0.1 mm and for 1/8th (OD) is +/- 0.2 mm
Our PTFE tubing is a low density, coherent fibrous structure.
Please be aware that all PTFE tubing contains micro-pores in the tubing wall. These micro-pores allow for a quick air exchange. This is of special consideration for degassed and oxygen-sensitive solvents. Our PTFE tubing is extruded from virgin PTFE that has Food contact compliance per FDA 21 CFR 177.1550 or EU regulation no. 10/2011.
