6. Do one of the following:
• For a solvent-side check valve, reconnect the solvent inlet line.
• For a waste-side check valve, reconnect the waste line.

IMPORTANT The EASY-nLC 1200 requires nanoViper fitting systems with a specified
pressure range up to 1200 bar. Older versions are only specified up to 1000 bar. The new
1200 bar nanoViper fitting system consists of blue PEEK tubing, which distinguishes it
from the beige 1000 bar version, see

For the EASY-nLC instrument, most of the plumbing connections are made with nanoViper
fittings (Figure 65).
