HPLC Column End Fittings - Preparative and Semi-prepative

HPLC column end fittings

Semi-preparative and prep column end fittings have .4 mm and .75 mm bores, respectively. All make up on the column with external fittings, and are available with or without a removable 2 micron frit installed.

Standard material is Type 316 stainless.

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.
