Seal Wear-in Procedure

Put a bottle with 100 ml of isopropanol in the solvent cabinet and place the solvent intake filter of the pump head you want to wear in into this bottle.

Screw the 0100-1847 (PEEK adapter 1/4-28 to 10-32) onto the active inlet valve and connect the inlet tube from the bottle head directly to it.

Connect the 5022-2159 (Restriction capillary, SST 0.12 mm ID, 2 m long) to the purge valve. Connect its other end to a waste container.

Open the purge valve and purge the system for 5 min with isopropanol at a flow rate of 2 mL/min.

Close the purge valve, set the flow to a value that gives a pressure of 580 bar. Pump 15 min at this pressure to wear the seals in. The pressure can be monitored with the Instant Pilot, chromatographic data system or any other controlling device connected to your pump.

Turn OFF the pump, slowly open the purge valve to release the pressure from the system, disconnect the restriction capillary and reconnect the outlet capillary to the purge valve. Reconnect the intake tubing to the solvent selection valve and the connecting tube from the solvent selection valve (if installed) to the AIV.

Purge your system with the solvent used for your next application.
