nal frit aswell as a replaceable cap frit,which easily canbe changedwithout disturbing
thepackedbed.Changing the external frit can reverse the effects of accumulatedparti-
cles, such as high backpressure or peak distortion. To obtain this basic configuration,
simplyorder anyRestekHPLC column, and add the suffix -700 to the catalognumber
for the column. (Nominal additional charge.)
