Technical Data
| 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.
