Capillaries made from stainless steel and tubings made from PEEK are most often used in HPLC.KNAUER offers precut capillaries as well as standard capillaries that can be cut by the user.
This connection system is recommended for all connections in a standard AZURA Analytical system. It incorporates flexible 1/32” OD tubing to easily route through your system. The fitting is already installed on each capillary.
