Low Pressure Tubing
Useful for HPLC & Low Pressure LC

• PTFE • FEP • ETFE • PFA • Most Popular

Used before the injector and after the detector on all HPLC Systems: 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 based on your specific needs.

PTFE Tubing (PolyTetraFlourEthylene) - Lowest Cost
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.

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) - Highest Pressure Rated for MP Tubing
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.

PFA Tubing (PerFlourAlkoxy) - Similar to PTFE, Less Permeable
All of MicroSolv PFA capillaries are extruded from virgin PFA manufactured exclusively by Dupont. We do not add any additives to the original PFA 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.
