Installation of Seal Wash Function
The 1290 Infinity Quaternary Pump has a built-in seal wash function. The Seal
Wash Function 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.
