Removing Capillaries

Potential damage of capillaries
C AU T I O N
➔
To keep the flow path free of stainless steel, the front end of the capillary is
made of PEEK. Under high pressure, or when in contact with some solvents,
PEEK can expand to the shape of the connector where the capillary is
installed. If the capillary is removed, this may become visible as a small step.
In such cases, do not try to pull the fitting from the capillary, as this can
destroy the front part of the capillary. Instead, carefully pull it to the rear.
During installation of the capillary, the fitting will end up in the correct
position.
