Installation of Seal Wash Option
The 1290 Infinity Quaternary Pump is optionally available with a seal
wash function. This option is recommended when using buffers or other
non- volatile solvents or additives that could deposit on pistons and seals.
It is used for regularly cleaning these parts automatically.
1 Place a wash solvent reservoir into the solvent cabinet. A mixture of
distilled water and isopropanol (90/10) is a good choice for many
applications.
2 Put the solvent inlet tube into the solvent reservoir, close it and connect
the tube to the seal wash pump.
3 Route the outlet of the wash tube into a waste container.
