PFA Tubing (PerFlourAlkoxy)
All of Applied Research PFA capillaries are extruded from virgin PFA manufactured exclusively by Dupont. We do not add any additives to the original PTFE material, except for color particles in the solid-colored tubing. PFA tubing and capillaries do not contain micro-pores in the tubing wall to the same extend as PTFE tubing and capillaries.

| 2.0 mm and above: | +/- 0.10 mm |
FEP Tubing (Fluorinated Ethylene Propylene)
All of Applied Research FEP capillaries are extruded from virgin FEP.
FEP is especially useful in ion chromatography applications. Do not use FEP above 80C.

ETFE Tubing (TEFZEL)
All of Applied Research ETFE tubing and capillaries are extruded from virgin ETFE. We do not add any additives to the original ETFE material.
ETFE tubing and capillaries are widely used in all low- and medium pressure laboratory applications due to the relatively high burst-pressure.
Please be aware that ETFE tubing is not resistant to all chemicals. Some organic solvents may cause swelling and reduce the pressure stability.

Note: The data collected in column ’Pressure’ show the recommended permanent maximum working pressure at room temperature for non-destructive solvents.
Change of solvents and temperature may result in lowered mechanical stability.
Keep in mind that tight bends of the tubing, use of wrong tools for cutting and bad connections may result in mechanical damage to the tube and by this reduce the pressure stability.
