PTFE Tubing
ARE-Applied Research™ brand PTFE tubing and capillaries are extruded from virgin PTFE. We do not add any additives to the original PTFE material,
except for color particles in the solid colored tubing. PTFE tubing and capillaries are widely used in all low-pressure laboratory applications
including in the low pressure zones of HPLC mobile phase handling. Please be aware that all PTFE tubing does contain micro-pores in the tubing
wall and will allow a quick air exchange. This is of special consideration for degassed and oxygen-sensitive solvents.
Tolerances for PTFE Tubing and Capillaries:
| up to 2.0 mm ID: | +/- 0.10 mm |
| 2.0 mm ID and above: | +/- 0.20 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.
