Teflon PTFE & Teflon-Like Tubing
|
|
PTFE Tubing
PTFE tubing (PolyTetraFluorEthylene) is chemically inert and
suitable for lower pressure applications. Typically 1/16"
OD tubing holds up to 62 bar (900 psi) and 1/8" up to 35
bar (500 psi).

We do not recommend using FEP tubing above 80°C.
We can also supply our PTFE tubing color coded to make it easier to
identify the ID and to differentiate between the streams. Our unique
process when adding color is your guarantee that there is no leaching
- color permanence is ensured.
Black PTFE Tubing
Teflon is translucent and for certain light sensitive applications we
recommend to use black PTFE tubing. So far we recommend it for: -
Light sensitive enzymatic reactions - Luminescent reactions -
Connections for the flow-cell - Radioactive HPLC
PFA Tubing
PFA tubing (PerFluorAlkoxy) has excellent chemical stability and
mechanical strength. Always use PFA instead of PTFE if gas
permeability is the issue. 1/16" OD high purity tubing has a
maximum pressure rating of up to 100 bar (1450 psi), while 1/8"
OD maximum 72 bar (1050 psi).
FEP Tubing
FEP (FluorinatedEthylenePropylene) is chemically inert to most HPLC
solvents and is recommended for low pressure applications. Typically
1/16" OD holds up to 117 bar (1700 psi) and 1/8" holds up to
70 bar (1000 psi). We recommend FEP for ion chromatography
applications. We do not recommend using FEP tubing above 80°C.
