1 Cut the ends of the tubing at a 90- degree angle to prevent leakage or

tubing should protrude between 0.5 and 1.0 mm beyond the front ferrule.

3 Insert the end of the Teflon tubing into the connector block as far as
possible. Next, slide the Teflon nut and tighten the Teflon nut into the
connector block.
To reduce the dead volume, keep the Teflon tubing pushed in as far as
possible until the connection is finished. This will align the tip of the
tube and the tip of the nut.
