Tubing and Capillaries
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 colour particles in the solid coloured tubing.
PFA tubing and capillaries do not contain micro-pores in the tubing wall to the same extend as PTFE tubing
and capillaries.

Tolerances for PFA tubing and capillaries is as follows:
| up to 2.0 mm: | +/- 0.05 mm |
| 2.0 mm and above: | +/- 0.10 mm |
FEP Tubing (FlourinatedEthylenePropylene)
All of Applied Research FEP capillaries are extruded from virgin FEP.
FEP is especially useful in ionchromatography applications. Do not use FEP above 80C.

| 44.635.435.00 | Tubing, FEP, 1/4" OD x 4.35 mm ID | 45 / 650 |
Tolerances for FEP tubing and capillaries is as follows:
| up to 2.0 mm: | +/- 0.05 mm |
| 2.0 mm and above: | +/- 0.10 mm |
ETFE Tubing (TEFZEL)
All of Applied Research ETFE tubings 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 resistent to all chemicals. Some organic solvaents may cause swelling and reduce the pressure stability.

| 45.318.159.00 | Tubing, ETFE, 1/8" OD x 1/16" ID | 110 / 1600 |
Tolerances for ETFE tubing and capillaries is as follows:
| up to 2.0 mm: | +/- 0.05 mm |
| 2.0 mm and above: | +/- 0.10 mm |
Note: The data collecected in column ’Pressure’ show the recommended permament
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.
