Pre column filter

The pre column filter is installed in front of the column to prevent bacteria and small particles in the sample, as well as impurities from the mobile phase and seal, which can affect the lifespan and analysis results of the column. The pre column filter has0.50mm(0.2")The through-hole and10°The distribution cone of angles ensures the minimum spectral band expansion and local vortices, and the sieve plate aperture2mThe built-in sieve plate of the filter should be replaced regularly depending on the usage time and the condition of the mobile phase.
