Low Pressure Tubing Specifications
PFA Tubing (PerFlourAlkoxy)
All of MicroSolv 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.

FEP Tubing (FlourinatedEthylenePropylene)
All of MicroSolv FEP low pressure tubing is extruded from virgin FEP. FEP is especially useful in ion-chromatography
applications. Do not use FEP above 80C.

ETFE Tubing (TEFZEL)
All of MicroSolv ETFE tubing is extruded from virgin ETFE. We do not add any additives to the original ETFE material. ETFE
tubing is 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.

PTFE Tubing (PolyTetraFlourEthylene)
PTFE tubing is widely used in all low-pressure laboratory applications. Please be aware that all PTFE tubing does contain
micro-pores in the tubing wall. These micro-pores allow a quick air exchange. This is of special consideration for degassed
and oxygen-sensitive solvents.
All MicroSolv PTFE tubing is extruded from virgin PTFE manufactured exclusively by Dupont, the original manufacturer of PTFE
material. We do not add any additives to the original PTFE material, except for color particles in the solid colored tubing.

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.
