High-pressure capillaries are produced from the high-performance plastics PEEK, ETFE, PTFE, FEP, PFA, and MFA
High-pressure capillaries are indispensable in analytical chemistry, process control, and laboratory technology. Their primary function is the precise transport of small quantities of liquids under high pressure — as required, for example, in high-performance liquid chromatography (HPLC), sample preparation, or continuous process monitoring. Particularly in biotechnology, pharmaceutical research, and the chemical industry, these capillaries are valued for their precision, chemical resistance, and purity. The correct selection of material and specifications is essential to ensure reliability and efficiency in operation.
Detailed product descriptions of high-pressure capillaries
High-pressure capillaries made from high-performance plastics such as PEEK, ETFE, FEP, PFA, PTFE, and MFA provide tailored solutions for extreme pressure conditions. Each material offers specific advantages in terms of pressure and temperature resistance. PEEK stands out with a pressure resistance of up to 420 bar at +20 °C and a temperature range from –40 °C to +220 °C. ETFE follows with 185 bar and a range from –20 °C to +150 °C, while FEP withstands 34 bar between –170 °C and +200 °C. PFA operates at 20 bar and covers an exceptional range from –260 °C to +260 °C, and MFA reaches 26 bar between –70 °C and +240 °C.
PEEK high-pressure capillaries
These striped high-pressure tubes offer maximum stability and biocompatibility. With pressure resistance up to 420 bar and temperatures from –40 °C to +250 °C (short-term up to +300 °C), they are suited for the most demanding applications. They resist all chemicals except concentrated sulfuric acid, nitric acid, and aqua regia.
PEEK spiral capillaries
Available in various colors, these capillaries tolerate pressures up to 450 bar at +20 °C. With an outer diameter of 1.6 mm and inner diameters from 0.13 mm to 0.76 mm, working lengths between 400 mm and 1300 mm are available.
ETFE capillaries
Particularly suited for metal-free HPLC systems, these capillaries withstand pressures up to 185 bar. Their operating range from –200 °C to +150 °C (short-term up to +200 °C) and their biocompatibility make them ideal for bioactive applications.
PFA capillaries
These high-pressure capillaries are used in chemical process engineering, offering an impressive temperature range from –260 °C to +260 °C (short-term up to +285 °C) at pressures up to 20 bar.
FEP capillaries
With compliance to FDA and BfR (German Federal Institute for Risk Assessment) standards, these capillaries are particularly suited for small-scale production systems and biochemical processes. They offer pressure resistance up to 20 bar and withstand temperatures from –170 °C to +200 °C.
MFA capillaries
The transparent fluoropolymer offers exceptional thermal and mechanical strength. With a Shore hardness of D 59° and a temperature range from –70 °C to +240 °C, MFA capillaries are ideal for applications in biotechnology and semiconductor engineering.
