Checking and Cleaning the Solvent Inlet Filters
A blocked filter does not affect the pressure readings of the preparative pump. The pressure
readings cannot be used to check whether the filter is blocked or not.
If the filter is in good condition the solvent will freely run out of the solvent tube (due to
hydrostatic pressure). If the solvent filter is partly blocked only little solvent will drip out of
the solvent tube.
When opening capillary or tube fittings solvents may leak out.
The handling of toxic and hazardous solvents and reagents can hold health risks.
➔ Please observe appropriate safety procedures (for example, goggles, safety gloves
and protective clothing) as described in the material handling and safety data sheet
supplied by the solvent vendor, especially when toxic or hazardous solvents are
used.
Small particles can permanently block the capillaries and valves of the module.
Damage of the module.
➔ Always filter solvents.
