Using the Pump
Prevent Blocking of Solvent Filters
Cleaning the Solvent Filters
• Remove the blocked solvent filter from the bottle-head assembly and place
it in a beaker with concentrated nitric acid (35%) for one hour.
•
Thoroughly flush the filter with HPLC-grade water (remove all nitric acid,
some capillary columns can be damaged by nitric acid).
•
Replace the filter.
WA R N I N G
When opening capillary or tube fittings, solvents may leak out.
The handling of toxic and hazardous solvents and reagents can carry health risks.
➔
Observe appropriate safety procedures (for example, wear 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.
N O T E
Never use the system without solvent filter installed.
