Shimadzu WondaDisc Needle Filter (100/pack, item number: 8810-11322)

Impurities in samples and solvents not only easily cause damage to liquid phase pumps, injection valves, chromatography columns, etc., but also often affect analysis results. Therefore, pre filtering the sample and solvent through r-n can not only effectively reduce pump wear, prevent blockage of the injection valve, pipeline, and chromatographic column, but also greatly reduce the interference of impurities on the chromatogram, thereby improving sensitivity and r-n accuracy.
