How to adjust the O-ring in an I-Class or ACQUITY UPC2 SM-FL - WKB319503
Article number: 319503
OBJECTIVE or GOAL
Adjust the Sample Manager - Fixed Loop (SM-FL) O-ring.
ENVIRONMENT
- ACQUITY UPLC I-Class
- ACQUITY UPLC I-Class PLUS
- ACQUITY UPC2 System
PROCEDURE
- Open the sample compartment door and the fluidics compartment door.
- Using a T20 TORX driver, loosen the two captive screws that secure the access panel.

- Insert a piece of used PEEK needle or PEEK tubing into the needle wash seal port, and gently push the needle down through the O-ring. You should feel slight resistance as the needle slides through the O-ring.

- If you do not feel slight resistance while sliding the needle through the O-ring, the needle wash seal port is probably too tight or too loose. Manually adjust the needle wash seal port until you can verify that it is seated correctly. (CAUTION: TO AVOID DAMAGING THE O-RING SEAL AND NEEDLE, DO NOT OVER-TIGHTEN THE NEEDLE WASH SEAL PORT).
- Remove the PEEK needle or PEEK tubing from the needle wash seal port.
