Tubing from IDEX are available in a variety of different materials and dimensions. The product range extends from biocompatible PEEK to stainless steel and flouropolymers (such as FEP and PFA) tubing. Besides the tubing, IDEX also offers the appropriate cutting tools.
| Capillary | Capillary description | Inner diameter / " |
| PEEK | biocompatible; chemically inert to most solvents; flexible | 0.001-0.080 |
| Capillary PEEK | same properties as PEEK with smaller outer diameters | 0.001-.0.020 |
| Fused Silica | narrow tolerances; suitable for micro- and nano-HPLC and electrophoresis | 0.0008-0.006 |
| Stainless steel | Large selection of outer and inner diameters | 0.004-0.080 |
| PEEKsil | mechanically very stable; suitable for polymer and stainless steel fittings | 0.001-0.012 |
| PFA | excellent chemical compatibility; suitable for critical, low pressure applications | 0.020-0.062 |
| High Purity PFA | high purity PFA; low contamination; suitable for medical, diagnostic, pharmaceutical and biotechnology applications | 0.020-0.188 |
| 360 μm high purity PFA | Same properties as High Purity PFA with a smaller outer and inner diameter | 0.002-0.006 |
| FEP | Alternative to PEEK capillaries; chemically inert to most solvents; easy to cut; suitable for low-pressure applications | 0.003-0.250 |
| ETFE | suitable for aqueous applications; more robust than PTFE, FEP and PFA | 0.010-0.188 |
All capillaries are available in various inner diameters, lengths and, in some cases, colours. We will be happy to help you select the right capillaries for your application.
