TECH TIPS

  • When packing columns, use Valco's through-type unions to couple the column to the packing reservoir.
  • Standard column end fittings are Type 316 stainless, but since the column wall and frit form over 99% of the column surface area, standard fittings with titanium frits can generally be used on inert columns.
