HPLC Column End Fittings - Replacement Frits

replacement frits

Replacement frits are available in stainless and Hastelloy C (although most Hastelloy C frits are special order items).

1/16", 1/8" and 1/4" frits are sold in packages of 10. 3/8", 1/2", and 1" frits are sold individually.

If a temporary frit is used during column packing, the frit OD should match the column OD. Permanent frits should have an OD matched to the column ID, and should be pressed in to give the lowest dead volume.

Other sizes may be available or special-ordered in OEM quantities.

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.
